Welcome everyone to the 2021 CCS Summer Symposium. We wish we could do this in person as we have done in the previous years, but we'll make the best of it. Considering that at least the labs for open anyone able to go and do the research. So this is a great opportunity in a way for everybody else to learn about what you have been doing and what have you enjoyed the most with this research? So what we're gonna do is we're going to have three sessions. And in each session there'll be 10 or 11 presenters and they'll have two minutes each. And it'll be like a elevator pitch where they will talk very quickly about the poster and attract you to come and look at their poster in the breakout rooms. So what we'll do is after these two minute talks to our YOU CAN will have breakout rooms and you can move from one room to another. And the presenters will be there to answer your questions. And then in the last five or 10 minutes, you get a Google link and then you can vote on each poster. Because remember the, the voting which used to be done in person, we, we pick the first, second, third, based on your voting. There is no other no other system use. So it's just going to be the voting of, obviously it will be averaged for the number of voters. So that's the plan. I'm Suresh Advani, I'm the Associate Director at the Center of composite materials and a Professor in Mechanical Engineering. And so with that, I think we can get started. What I would like each presenter to do for me introducing them is that when I call their name, they introduce themselves and tell us what department you are in and you know about they are basically how they about the center and decided to do the summer research and what their experience has been. And then they can talk about the poster. So what I will do is I will bring up your poster. I have it all here. And as I bring up your poster, that person should basically turn their video on so everybody can see them and, and then talk about themselves before they talk about their poster. So let's gets, Are there any questions before I start? Okay. So our first speaker is Henry food low. So a Henry. Hello. Yes, we can hear you. Hi. So my name is Henry fellow. I'm an undergraduate mechanical engineer here at the University of Delaware. I heard about the CCM through Professor Anthony. And in taking is heat transfer class, he reached out to some students about an open position under Dr. Tom centered doing some research on tough. And I was interested in the opportunity and here I am and I really enjoyed working here the summer and I've learned a bunch. So with that, I'll get into what I learned this summer. I was investigating the extensional viscosity of tough composites in stretch forming processes. And like I said, I was working under Dr. Tom center and with the help of Dr. paddles, so MiSeq and Professor Anthony. So an introduction into tailored universal feedstock performing tough is a highly aligned short fiber composite with very high fiber volume fraction. The fibers are oriented unidirectional at the Apply Scale. And this creates an isotropic behaviors in which it is very strongly the fiber direction and not nearly as strong in the transverse direction. And the discontinuous nature of the fibers within the polymer suspension last for stretching in the fiber direction, which is something that could not be said for its continuous fiber counterparts, and therefore makes tough a very highly formable material or composite. The goals of my investigation the summer, were to determine the fiber direction viscosity eta 11, which will be fit into our material model and ultimately used for finite element material forming simulations to tell us more about the vulnerability of the material. For the testing that we did. We applied uni-axial tension in the instrument at constant temperature and strain rate. And approximating a to one want to be the longitudinal stress over strain rate. We're able to determine viscous behavior up material in the fiber direction. We also use digital image correlation to find the surface strain during testing, which could tell us more about the local deformation of microstructure, as well as obtaining more accurate data in the cage section, as compared to simply calling the strain from the instrument. And going into the results that we obtained, first, we determine the tourist little strain dependence of the viscosity and the fiber direction. Which meant that we could model viscosity as simply a function of temperature and strain rate. And doing so, we were able to observe that viscosity behave as a power-law fluid. We're sorry, tough, behave as power-law fluid and fiber direction stretching and more specifically a shear thinning fluid. And this knowledge is supported through our our knowledge of shear magnification, which occurs due to the large fiber aspect ratios. So if you'd like, learn more about my research methodologies the summer, feel free to stop by my poster at the end of the session. Thank you so much. Thanks Henry. Our next speaker, because Neal. Neal, can you turn on your video and introduce yourself and then you can talk about your poster. All right, So my name is Neil care and I'm a chemical engineering student, not be a rising junior here at University of Delaware. And I found out about CCNE through a friend and I was able to reach out and I got put on the sort of project under Dr. Derek Heider. And my poster is on the closed-loop recycling of carbon fiber reinforced polymers into highly aligned high-performance short fiber composites using the tough process. And specifically looking at five-year recovery through pyrolysis. And as mentioned before, I worked under not only toxic, they're tighter but mystery. They Karen Blackett. So just the premise of my research is that producing carbon fibers is a very energy intensive process and can be very expensive. But recovery solutions to exist through a medium like a solvolysis and paralysis. But one, recovering these fibers, they must exhibit like high modulus and shrink that attention along with good interfacial shear strength. And the recovery solution that we chose to look at was a parallels this cycle where we plan to retain about 90 to 95 percent of virgin fiber properties. And then what we plan to do actor is to use these recycled fibers to manufacturer top panels. So in order to actually create a good parallels the cycle we developed an iterative process, as can be seen in the testing approach, where we first place like a grid inside of a thermo gravimetric analysis where we can find the ideal temperature. And basically I dwell temperature is when it is exposed to air. And the air environment does is it actually warns oxidation which helps burn up any residual remains of resin on the fiber surface. And after this initial run on the initial dwell time that we find and finding a good temperature we scale does a GLM furnace where we run it at the initial dwell time. And as we're heating up the fibers, they're under nitrogen environment to avoid any premature degradation. So after the GLM run, we check dispersion by submerging the fibers in 99.9% isopropyl solution. And dispersion, good relative to what is called a different run, will average the dwell times and then conducting do you run. And if the dispersion isn't good, effect will increase the dwell time by a factor of two. And once the ideal dwell time is found, we can optimize the process from the gas environments. So in terms of funding the ideal temperature, we found that 500 degrees was the, was the best as 450 degrees was too low and actually had really bad dispersion. But even at 550 degrees, you've done that the dispersion was significantly better. The fiber degradation was just much too high. So for our results, we were able to iterate through the old times of the initial TGA run, which is 69 minutes and be iterated all the way up to 100 minutes. And the general trend that we found was that higher dwell times like to higher percentage of fibers dispersing with the 100 minute to all-time run, shoving the best dispersion. And in the future we would like to look into additives. I would weren't for better dispersion of the fibers. And then to manufacturer tough panels and actually investigate their composite properties. Thank you for listening. Thank you Neil. So remember about Sokoto meals poster later on. The next as Nicholas. Nicholas, can you. Hi, my name is Nicholas so Rasinski. I I'm a biomedical engineer here, Delaware. And I heard about the internship program probably about five years ago. I was approached by Dr. Dirk tighter and I've been working for him ever since. So my project is automation and composite research. The goal of my project is to take the different programs I'm on and automate the processes within in order to increase efficiency and decrease human error. The first project I'm honestly I wrap program and within the eyebrow program, we are attempting to fix underground methane pipes that are leaking with a composite preform. And the fast mode manufacturing cell project is to create small parts efficiency efficiently and quickly with tough material. There's four key parts with the IRA program that we're trying to automate. That is the we're trying to automate the lay-up and to create how we create the preform using the Winder, which is the image in the top right. The expander is brought into the tube, which is the second image on the right. And it drags through the pipe, expanding the preform and sealing the pipe. The third image is the internals of the Winder, which had to be completely gutted, reprogrammed, and rebuilt. And the fourth image is the mandrel, which is used to collapsed to preform so that it can be easily transported to the job site. With the fastball manufacturing cell project, we're attempting to automate it using the robot in the bottom right and the press in the top-left. Doing so, we will have the robot pool the part out of the oven after it's blasted with IR bulbs and then place into the press F4 press molding. That image in the bottom left is one of our pieces under the IR camera. And you can see we have good homogeneous heating there. And the next steps for these programs are to figure out the exact material properties for the preform and the IRR program. How exactly we're going to do our layout for the program. How we're going to transport the pre-formed from the lab to the job site and then into the pipe. And the exact design of the expander. And for the fastball manufacturing so project, we need to continue to work on embedding closed-loop heating and cooling within the press as we're having on eating heated, uneven heating and cooling, as well as reduce the cycle time. In conclusion, automation is important because reduce the cycle time, cost, human error and risk. And I've gained extensive experienced the summer through electrical wiring experienced by rehabilitating the Winder, extensive cat experienced through 3D modeling parts for this, as well as programming the PLC using click. And I've got machining in general, hands-on experience through working with these machines, as well as I'd like to thank Dr. Dirk tighter for the opportunity to work with him and for all his help the summer. And if you have any other further questions, you can ask me my breakout room. Thank you. Thanks, Nick. Next speaker is Kayla. Kayla, can you oh, yeah, Sorry. My name's Caleb. I am a unicorn and video video on. Yeah. Hi. My name. I am a mechanical engineering major and my project optimization for that calf material. So we collect good data to optimize normal patch. Because currently the Huffman, the patch and chocolate with pretty file and costly. And in autarky you can make adequate can't get to the processing a clear and complete picture of the Earth and analyze them. Wedge, angle and velocity, my theta and alpha. So as you can see, we found that the light petitioning really affected what fiber orientations were able to see in the picture. The thigh biting revealed more vertically oriented fibers, while the top lighting will yield more horizontally oriented fibers. And we define the optimal lighting that we can use to find the data that we needed. And with that, the velocity ranged from about four millimeters per second to 1400 tiny 20 millimeters per second, and move forward. More data can be taken towards the bottom either. So I might add a quick changes to the process about academia more efficiently. Thank you. Thank you, Kayla. And please go to a poster after the presentations. Next speaker is Alexandra from high-school, New York charter high school. Alexandra, you that k doesn't look like she's there. So we'll move on to the next one. That's very tiny. Alex is here. Here are, our check is found. I will come back to you, check your sounds and, and we'll come back to you after the next speaker. Okay, so the next speaker is James Stallman. James, Hi, my name is James Tolman. I'm a material science undergrad advising junior. I'm studying at Cornell University, but until the summer, I found out about SCCM just on the web and ask them if they had any openings and they did. So I ended up walking the talk that assemble and I ended up really loving the research process. And I think this has changed kind of even microbial path going followed. So what we worked on this summer, my poster is about evaluation of sofas, sweat ability of thin silo encoded glass fibers. Clique also to this was that we have a chemical vapour deposition process which takes advantage of low cholesterol ambient temperature environments to apply silence on to classify vowels. And we have no facial shields strength data that shows an improvement in the fiber matrix interface of these firewalls. However, the question has been, an interfacial shear strength scales up to punch you as well as other mechanical properties. However, the question has been for a while, Can we, how do we characterize the surface of what will depositing? Because it is too small to see using optical microscopy, etc. So what we've come up with is using contact angle measurements to do this characterization, contact angle is a function of sulfur central G. So basically liquids have surface tension, solids have sulfur central chief and contact angle is the angle that a, a liquid will make with a solid. So a contact angle of 90 will be kind of like a droplet with 90 degree angles. A contact angle of 0 will be totally wedding and what the complete sulfurs. So weldability comes into play with all of this. And what we can do is detect the changes in contact angle as we have different dwell times with these measurements. So CCM has a tensiometer, dynamic contact angle measurement. So what it does is by measuring the change in weight of a single firewall as it is placed into a liquid, you can get a angle out of that from the changes in weight. And we can also measure diagonal using this approach. And so what I'm going to be talking about in my breakout room is, is there evidence of changes in surface chemistry with deposition times? How accurate are the diagonal measurements we can get using the dynamic contact angle testable at CCM. And what else can we do with contact angle measurements? So I hope to see what my session so that we can talk about this as well as I can cancel any other questions. Thank you. Thank you, James. Next speaker is Austin Barry. Austin, lie and literary theory. Go ahead. Yeah. Hi, I'm awesome. Dairy. I am a rising senior at Lafayette College and I actually found out about SCCM five years ago through jury Stratton. She knew I was interested in engineering when I was in high school and reached out and said, would you want to work at VCM? And I said yes, and kinda been here ever since. So here is my presentation manufacturing or they call custom carbon fiber ankle foot or Thursdays. Custom carpet fiber ankle foot parentheses are manufactured for people post-stroke. Also known as LFOs. The customer carbon fiber ankle, foot or Thursdays provide stability and maneuverability based on individual patients needed support. Each AFL has a tailored to their crime citation. When manufacturing in AFL apply to generated based on anatomical measurements and the step is requirements for each patient. The footplate of the AFL, it designed in a manner that provides a natural rocky motion that can be seen in the picture on the right. The devices have a low profile and maintain a comfortable fit or maintain a lightweight in order to have a comfortable plate rotation. If those are done in a two-step manufacturing process with the footplate and struck down in one process and the cough done in another process. They eventually joined together. After the manufacturer has done, it goes through quality assessment. Manufactured FIFO's are visually inspected for any defects such as the laminations or wrinkles. The stiffness of each FIFO is tested to ensure the comfort of the patient is met. And the strut height, width, and footplate geometry are made in order to ensure that it is a good fit for each patient. While I if those are being used currently, there's future work to be done. The future work that we continue to work is standardizing the quality assessment practices, optimizing apply generation, improving the manufacturing quality further, and developing a new footplate geometry based on patron requirements. Thank you for listening to my presentation. And if you have any questions, please come to my poster session. Thank you. Next speaker is Kenneth Olson. Hello, my name's KJ Olsen. I am a rising junior here at the University of Delaware with the civil engineering department. My project or research or summer was working at introducing thermoset plastic material into high-performance concrete for a roadway surfaces. Or main objective was to take these recycle non recyclable thermoset plastics that mostly end up in landfills or end up being burned. In. Finding a way to recycle them by introducing them into high-performance concrete mixes. For this, we took ABS plastic chips. We're provided us through a local recycling plant, ego politics of Delaware. And we used a common you HPC mix with the ingredients listed there. And we look at different percentages of the plastics in the mix and tested the overall compressive strength for a baseline effect of the plastic. As for our first week was old switch, I'm still working on it and continue my research. We saw that there was an overall good retention awaiting and a 1.52, 2% plastic introduction by weight. Which overall, on a larger scale, there would be a good way to a cycle these thermoset plastics into different concrete mixes and we're looking to further do further testing. And if you have any questions, come to my meeting. We're talking about doing different plastic powders, different shapes of plastics, and doing more testing da, further explore this topic. Thank you. Next speaker is Daniel. How to everybody? My name is Danny theme and I am a graduate student at the University of Alabama. And I worked here the summer as well as two summers ago. I heard about SCCM through three strand has been family friend for really long time. She knew that I enjoyed the sciences and so this was a pretty awesome opportunity. I've had a lot of fun. This summer. I worked on stabilizing tough by electrospinning ultra low Aereo late binder veils. We've already kind of gone over. What's tough is, so I don't need to really talk about that anymore. One of the biggest problems with tough is that before any caring process is done, the material can be kind of difficult to handle because the discontinuous nature of the fibers makes it so that there's very few inter fiber interactions. So when you pick it up, it has a tendency to sort of fall apart under its own weight. So electrospinning is a good potential solution to that because it allows a very low weight binder to be applied to the surfaces of the fibers to sort of hold everything together. The two biggest problems with electrospinning that we've found so far, or that we've only been able to show it with As you just chemicals hazardous both people and the environment. And we've only been able to use a single needle for application. Which makes it kind of both of those things together make it kind of impractical and sort of commercial settings. So this summer we wanna do address those two things. The first thing was the number of needles. We wanted to build a setup that used for needles just to sort of show that it was scalable, that you could use multiple. We did that by connecting a voltage source to a conductive plate and an injector. And the injector push resin towards the binder, towards some branched tubing, which then went all the way down to four needles. And the potential difference between the binder and the conductive play aloud the electrospinning to happen, which showed that we could use multiple needles and we used PVA polyvinyl alcohol as our binder, which is soluble in water and not hazardous to human health, making it both environmentally and human friendly and a much better binder overall. We wanted to show that we could do any of that. And it did succeed in electrospinning. You can sort of, well, it looks like one of the images and the Quad has disappeared. I had trouble with that one, but the it's on my poster so you can come to the breakout room and see that. But The picture in the very bottom, you can see the PVA lecture spawn tough sheet is holding up under its own weight. The dry tough sheet is not holding up later. So yeah, Bauer, the results were that we succeeded in both multiple needle setups and PVA. And if you wanna learn more about any parts of the project from a breakout room. Thank you, Danny. Is Alex? Alex, please. Turn on your video. Okay. Can you hear me? Yeah. Cool. Hello, everyone. My name is Alec Schneider. I'm a Senior Mechanical Engineering undergrad here at UT. So the past few years before this, I interned at a local composites automation company. So I knew a few people who got their start at CCM. And the spring, I also took Dr. thousands in experimental characterization of composites class, and I learned a lot from that. And when I got an email from SCCM for someone to look for resin characterization work, decided to pursue it. So the research that I was involved in the summer was the investigation of the influences of environmental conditioning on epoxy resin properties at high strain rates. So just a little bit of background. Epoxy resin systems are commonly used in ground vehicle armor. And due to the nature of these panels, they're subject to high strain rates. High strain rates are the sort of loading you see with projectile impacts, high velocity, high energy loading. The panels also see a variety of environmental conditions that can see temperatures from anywhere as low as negative 55, seat, as high as 76 C, and they can also see humidity levels as high as 88%. Currently, the relationship between these environmental conditions such as temperature and humidity, among others, and the epoxy resins mechanical properties is not widely understood, particularly at high strain rates. And so our goal became to characterize this relationship between the environmental conditions and the epoxy resins mechanical performance. So we did this by considering two different resonance systems, SC 15 and audio already see SE 15 is seeing wide use in the field. And already I already see is being looked at as a possible alternative, the SE 15, the samp. These two resonance samples were further divided into two groups. One being condition that room temperature and 0% relative humidity. So in other words, completely dry. And the other group was condition at basically the worst-case scenario, which was 76 degrees C and 88% relative humidity. This was to promote as much moisture absorption as we could samples, but then tested I'm going to split Hopkins and pressure bar with an environmental chamber. So split Hopkinson bar, it's high strain rate compression test and the simulates like a projectile impact. And the samples were tested at various high strain rates temperatures. So some of the observations we had were that the samples could condition that the worst-case scenario to 76 degrees C and 88% humidity showed somewhat linear degradation, yield stress and strain energy, and respond to temperature increases. And one thing to know is that 76 c was the, that was the thermal limit that the military set for this armor. And by the time we reach 76 degrees C, the yield stress was already down by about 40 percent and strain energy was down by about 30 percent. And we also noticed a strain rate dependent relationship and the yield stress exhibited a bi-linear behavior, which I could talk more about in my breakout room. So if you have any questions for me about this, come see me in the break out room. Thanks. Thanks Alex. Next speaker is TJ. Tj, please turn on your video and pleasant. Hello, can you hear me? Yeah. Awesome. My name is TJ for and I'm a junior undergraduate research interns studying mechanical engineering and eating. I found out about SCCM through an email that I received at the beginning of summer and by this petition that's open. And before I get into my talk, I guess I'll start with a little bit of a story. I remember last summer I was driving down the highway and I got a flat tire. My heart rate instantly began to climb. As I saw that bright red tire pressure light flashing on my dashboard, I had to pull over and patiently wait for someone to come and change it. Then most of us are pretty familiar with this situation. For me, air leak was a minor inconvenience, but for someone like an astronaut, air leaks can be life threatening. This summer I had the pleasure of working on testing the new space suit that is being developed for the mission is prescribed by the Artemis program with nasa. And your student must be able to withstand an impact and be able to maintain structural integrity with enough time for the astronaut to return safely to base before losing air. My primary objective was to evaluate the damage after various simulated impacts and measure the leak rate of the subsequent damage of the composite material being used. I needed to answer the question, how does the composite structure and the suit behave post impact in an environment with a pressure differential. Or in layman's terms, what happens if there's a hole in the suit? Well, in about answering this question and four steps, first, we made samples of the composite material using the same methods as the seat. Second, we hit the panels with different impact our heads to simulate different situations that are likely to occur there. And we perform two tests based on the critical rates of the suit that before I can experience failure. Finally, we analyze the total damage and observe the relationships between the various parameters and then we traits. They were able to conclude that the leak rate was dependent on many factors, such as the impact of type, the energy, surface damage of the panel. These relationships will allow the space you engineers at nasa to develop safety parameters for when it's needed actually operational. If you'd like to hear more about this project and get a more in-depth look at my procedure. Please feel free to come to my breakout room and I'd be more than happy to discuss and answer any questions. Thank you. Thank you, TJ. Okay. So I don't know if Alex is able to use my Alex, are you able to use your microphone? Can you hear me? Yeah, I can hear you. Okay. Let me get back to you. Slide here. Yeah, there you go. So my name out in the quarters, I'm a rising junior at charter high school. Oh, my supervisor that summer was Mr. out that early and I researched the process of measuring and interpreting area away at 5PM. So my study was to find and monitor, keep the feet and the fiber Erin or weight or FFTW measuring process, as well as locate areas that could use improvement. Mainly or Belgium formula, W equals weight divided by area. Destructing people SAW data that can be without the many factors, including but not limited to, human error, false and machinery and excessive material handling. The following question to arise, this uncertainty, raise any concerns to your purchase of question. I'm measuring the weight an area of a single tough coupon ten times, interpreted each value, average standard deviation, and coefficient of variability results. I further examined my poster to thumb as you tell, kind of positive outcome, observed a significantly lower COD when compared to patch repeatability studies, synthetically resulting in a 0.18% CLV worthy values previously around one to 2%. Further questions include, how does the imaginary process be modified? As well as asking if a process is really worth altering at all. Thank you. Great. Thank you, Alex. Now we have one more speaker who can't make it later on, so wants to go at this point. So I will stop sharing my screen because I don't have his court charged, so he'll bring up his quad chart. But before I do that, I just wanted to remind you that after his staff, I will open up the breakout rooms so you can wander around in different rooms for the next 30 minutes and then look at the chat box for the link to the Google Form 2. Complete the voting. Okay, so I'm going to stop my share here. Can everybody see my screen? Yeah. Everybody. My name is Michael and I worked under her doctor to one's group at Southern University and A&M College. And I'm a Mechanical Engineering Major. And the title of my summer research is the mechanical analysis of a chorus nylon polymer using the finite element method. So the idea of what we're trying to do is to optimize a strength to weight ratio of material. And you can do so by increasing the strength or lowering the weight. And we looked at the porosity into as an alternative to reduce the weight of the material. But some calculations are needed to optimize that level of porosity so you don't actually reduce the mechanical properties of the material. So that different different assignments were if there were other group and mine was to basically look at the mechanical properties and see if it matches what we read and literature. And from literature we know that the lowest values of information and stress or obtain materials having less than 50 percent porosity. So material with less than 50 percent porosity is what we were looking at. I'm going to validate that would be finite. I'm using Ansys Mechanical. I was able to do some simulations of bearing levels of porosity. Iterations of 030% processing 40 and 50 to see what ofcourse 60 to see what happens as we increase the porosity. In order to do so, I had to generate some type of assumptions. First one was the bros, the percentage along x, y, and z will be uniform. This makes the material isotropic and our loadings wouldn't matter it with direction. And the pores are discrete close cells with spherical geometry. This just makes it a lot easier in terms of the calculations on and the simulation time. And finally, because we were going to be using the DLP method to actually 3D print the final result. The resolution is fairly high, so the porosity due to the void spaces between each layer of the 3D printed results wouldn't be neglected. So taking a look at some of the maximum principle stress on each iterations, we see that going from three to four, which is 30% porosity to 40 percent porosity gives us lowest number. And we were able to graph that gradient on this slope. And we have a summary. Same. We can say that first optimizing their strength to weight ratio of material is very important. And the maximum principle stress, which is an indication of how the material will fail. The gradient, while the maximum principle stress was at its minimum. Between the porosity percentage is 40 to 50. If you would like to hear more about this research, please stop in my breakout room. And that is I have Thank you. Michael. So I guess we can you can now go choose the breakout rooms. I've created out rooms for 12 of the presenters, and I'm assigning them to different rooms. But you can, you can just go around and talk to them in then after about half an hour, 25 minutes, you can fill out the Google form, which will be in the link, and then we'll start the next session. So, so far it looks like it's gone. Okay, not many technical issues, so thank you again to all the presenters. You guys did a great job. And within a couple of minutes, you're able to explain what you've been doing. And I'll be going around also to listen to some of the details. So I'll see you guys back again in the main room at ten o'clock. Thank you all. Good morning everybody. Welcome back to Session 2 of this symposium. This is Sunday. I may associate Scientist at CCM and LD chairing this session. Data total eight, sorry, ten presentations. And each presentation will be for four minutes. I will request each president to introduce themselves first and tell how they learn about CCNE and why they are interested to learn as an intern at CCNE. Before presenting that fosters. And with that, I'd like to invite our first speaker up this session. Just for electron. Does Christopher please unmute yourself and turn on your videos and present your slides. Hello. Chris Oliver on this, I am a rising junior at the University of Delaware saying Material Science and Engineering. And I learned of the CCM through the army educational outreach program, through which I achieve my undergraduate apprenticeship. And I study the structure property relationships of blast systems using molecular dynamic simulations with the Health partnered Sanjeev Choudhury and Professor John Gillespie tune. So interaction between atoms with an aluminum oxide and magnesium oxide are critical for understanding the studying of the structure property relationships of multi-access eyeglass systems. Using molecular dynamics simulations, we were able to determine these relationships and they were carried out with lamps using Matsui and reacts FF force field to model the interatomic interactions of these compounds. Using these simulations, we modeled aluminum oxide, magnesium oxide given their different densities that are available in nature. These molecular dynamics models will be used to predict their structure and the predictions will be validated when compared with available experimental data. The first step of the procedure we used required the initial configuration of the miles we generated. Randomly packing the correct amount of atoms in a 3D box and a low density using the packable scribble. These models of aluminum oxide and magnesium oxide were then used as inputs. And the lamp simulations to make the glass structure by heating and cooling, as in the outline below and blue, which follows the formation of glass. Finally, mechanical tensile loading with reacts FF force field is performed to generate a stress-strain response to mechanical properties. Before images under the results and discussion section are the pack animal models I developed for aluminum oxide and magnesium oxide. The red being aluminum, the gray being oxygen, and the green being magnesium. And finally, the glass formation process is in progress. But when is complete, the developed model will be used to predict the stress strain responses to determine the mechanical properties of the systems like in the graph determine developed by you, Professor Young. And if you have any questions regarding my methodology results, please feel free to come to my breakout room. Thank you. Thank you. Next presented daddies. Long audio game. Please go ahead. Hello. I'm Tim Longoria. I'm an undergrad and chemical engineering with a computer science minor. I found out about SCCM through e-mails and my advisor. I also heard through my peers as a good place to work. So this summer I was doing research on the atomic level stress analysis in glass fibers. These glass fibers are found in optical fibers and as reinforcement in composite materials. The goal of the research is to understand the effect of surface defects on the mechanical properties of the glass fibers. Surface defects such as cracks, occur during creation and handling of these fibers. But the small-scale and these cracks make it harder to experimental study. Instead, molecular dynamics simulations that are used to studying them. I worked mostly with MATLAB scripts to process the simulation data and determine fracture energy released. I used to DJ integral approach, which for crime chuckling hardly stress from atomic stress or distress averages and smooth the atomics just data which has a lot of noise. I was able to improve the speed of the hardest for stress script, among other scripts significantly is improvement save hours and even days of time that would otherwise be spent running the scripts. If you have further questions, feel free to come to my pink or blue, and that is all. Thank you. Thank you, team. So next president that'd be bothered. A yellow duck. Fun. Yeah, we can hear you. Hi, I'm a pause a logo. I'm a sophomore in electrical engineering. And I found out about TCM through my mom. Told me about ALP and then I pass my projects this summer. We're of The Thomistic analysis, lot of composite interface and polyethylene fibers, which are actually two different projects to work on there, Dr. Sanjeev Choudhury and that professor at John Gillespie junior. So interphase is basically a region between fiber and the matrix whatsoever develops through diffusion and reaction during a composite manufacturing. Polyethylene fibers are enhanced strength and energy. Absorption fiber, which is basically used for soldiers to protect them from impacts. All know, the purpose of money. Friendship was essentially to create analyzer that composite interface, not create. Now I'm going to use pre and post-processing tools to create an AWS composite Africans, as well as assess the change in structure of the fibers during a transversal oppression. So basically what I did was I used MATLAB scripts to track a change in morphology. And you can see an example here in the top right slide of what I would do with my script. What could basically take the angles of the molecules as they're being compressed. And as with all pop of a developing a composite interphase models with defects to analyze what happens. So basically, what happens is what happens. As a result, we get a perfect interface that gives low energy absorption. Because we're making new interface trying to find interphase, let's better as well as bind a polyethylene fibers that are better. So we found out that under trance, first pressure phase transformation occurs near 21.5 GPA hydrostatic pressure for P crystal. And if you're interested in finding out more about what I did this summer, please check out my breakout room light. Thank you. So next we'll be adding the Beta. So good morning everyone. My name is Adam Rivera and I'm an undergraduate student studying Mechanical Engineer UD. I heard about this program from the nasa spacecraft, which I was awarded and given my supervisor Professor Dawson, and overall had a great experience. My project was about innovative textile based functional. Now composites for finger recognition, little background nanocomposites. It's a liquid base solution that can be applied by decoding or electrophoretic deposition, which had been previously used to increase strength, heat deflection, and enhance conductivity. However, more recent studies show that it's possible to use it. So resistive property to detect slight variations and move it, such as pressure applied to a pen while writing the word yellower. This ultimately got us thinking, what if we can make this into a flex sensing glove? Would advancement technology, virtual reality has became like the newest craze. However, that being said, the technology hasn't advanced enough where it could be accurate, lightweight, and cost effective. So what we did was test for different fabrics. I decoded each one and applied like silver Claudio to the ends attached to wires and test each one on a machine using unidirectional stretching and analyzing is resistive feedback. Overall, a gray and white fabric show the most promising results and was mains will fingers leave. After that, I made a 3D prosthetic hand that was controlled by an Arduino and for servo motors. I then put this thieves on each finger and tested that response for 90 and 180 degrees it bend to see how sensitive the sensor is really were, but it doesn't stop there. The main goal was to see if the sensors could not only read the data, but send out as well. After that, I use a simple circuit using a voltage divider rule and was able to remotely control the prosthetic hand using my fingers. The code use roughly 800 points of data. Matzo, a 180 degree servo. So therefore, it was incredibly accurate. After the success of this test, it was Anton to show like the durability of the fabric. So it went to a mini washing machine and then inspect it after the first fifth wash. In this case, EPD showed highly durable. It showed like very little deterioration of the coding. Overall, it's been proven that nanocomposites can be used as a highly accurate sensor. Not only accurate, but lightweight and cost efficient as well. Again, my name is Ed Rivera and if you enjoyed this presentation, I want to learn more to stop biasing my poster to get a more in-depth look at this permanent conducted. Thank you so much. Thank you. Yeah, doing so. Our next president, dots. Ally will get d and Andrew Stuck. My name's era, the Getty. I am a rising senior. I can't runs near IED. And I learned about CCNE through a family member. My name center stack. I'm also Senior Mechanical Engineering student. I learned about SCCM third sappy. And we've been working with Dr. Haacke on stochastic damage modelling of composites and automated data processing methods. So we're modelling ballistic impacts using mad 162 and Ls time on. Our objectives are to apply a stochastic distribution to material properties in the finite element method or in the finite element model. And automate the process enough computational data. So regaining her summer are and model has to be uniform material properties or the entire or the mat 162 parameters were not adjusted to accurately model our experimental ballistic impact, the results. And Fourier analysis, a two parameter, we run many simulations to adjust this value. And each simulation set, we need to reduce and analyze the data. So that can take up to hours per set. So for our task and it breaks, we have proved our model by a task distribution of material properties. Python script to assign railway generate material properties around the average to the elements of our model. And to help with the automation of the data and reducing his eyes net, we write a Python script to do that, which now instead of hours, it takes the air if you match or three seconds. And every invite you all to ask any questions with that cluster. Thank you, Ally and Andrew. I'll start. I I didn't know that is Eddie mission. So our next president, today's Eddie Goggin. Headache. Do you hear me? Yes. Hi, my name is Eric hang and I heard through SCCM just through an email. I got home before my freshman summer and have work there every summer since. It's effortless. And my project this summer was an investigation of strength and surface morphology of ultra high molecular weight polyethylene fibers extracted from which the fatigue panels. And I worked under Dr. Ahmed Abu provide and Dr. Joseph Tito. So the two types of panels we worked on the summer were consolidated, are hardwired on an unconsolidated or Schwarz-Bart. The Consolidate panels where sheets of polyethylene laminated together. And we had a baseline and fatigue panel to panel on underwent. But 230000 cycles of t for the short bark on they were cheat the polyethylene stitch together at the corners. And we also have a baseline SET panel on, but this 3D panel underwent twice the number of cycles. And for this project, we wanted to identify failure modes and morphological damage on the fiber surface and quantify strength of these fibers before and after the secret to do. In order to do this, we needed to extract single filaments without causing damage and specify the types of damage or failure modes caused by fatigue loading on the only two types of panels. And then we needed to correlate these failure modes to strength degradation. We use the scanning electron microscope to determine the types of damage on the fatigued panels. By extracting filaments from damaged areas. By soaking the fibers in THF for 24 hours, The Matrix. And for tensile testing, we wrap the fiber around the calf capstone and added double-sided tape to increase adhesion to the sample. We found that fibers from the fatigued panels, both the hard work of art exhibit a kink bends, fiber splitting and fibrillation. And we found that the average failures of the baseline panel fibers were essentially to tackle. And then we also found that the secrets of the average tensile strength of filaments in both the consolidated and unconsolidated panels. It had a significantly better an effect on the consolidated balance despite the fact that it underwent less the two. If you have any other questions, feel free to visit me and my break your breakout room, and thank you for your time. Thank you, Eric. Next, president, Daddy's a sparse IVY don't among Casper and I'm a recent graduate in Mechanical Engineering from Udi. I found out about SCCM through other labs that I had to outsource CCM from and also received an e-mail this past winter, decided to apply an accepted that position as an intern. So going into my research, have you ever watched a car chase and an action movie where the bad guy shoots the windshield, but it doesn't completely shatter. Well, how is that possible? Windshields are made of class. Well, the reason is because windshields and other glass structures made of multiple layers of glass laminates and adhesive inner layers. If one layer of the glass fractures adhesive inner layer prevents the next class layer and also completely fracturing. The same type of composite is the basis for my research with applications and transparent armor to both protect and provide visibility to those who use it. My research has to enter layered candidates that need to be characterized. Crystal flex, a TPU, and an epoxy. These inner layers tested were sandwiched between either glass or polycarbonate laminates in their structure. More specifically, characterization was done at extreme temperature ranges to compare how the inner layer bondage will behave within all applicable at temperatures, transparent armor may possibly see, which was set out by the army themselves. To test materials characterization, dilemma. It's an inner layers began as a larger four-by-four sheet. And we're set in an autoclave to increase the bondage between the two materials and then cured afterwards to retain the same properties. Next, the sheets were cut into smaller strips with the waterjet cutter and had not just cut out with a slot grinder in order to achieve the exact geometry necessary as per ASTM standards. Finally, I was able to testing Hector dies, the shared properties of the bondage using an Instron machine and compression. As you can see from the graph in the bottom right, the shear stress and cross had displacements are much different between room temperature and an extreme temperature. This data will further be used to characterize the adhesive used within real life scenarios. If you happen to have any question, you see me in my breakout room and give I don't. So next president that is guided mode, is it here? Yes. Okay. So I'm calm. Worse, I'm a Senior Mechanical Engineer at the University of Delaware. And I heard about SCCM through an email and I decided to apply. And I'm glad I did. So this summer I did research on investigating the effects of extreme environmental conditions on field strength of composite armor with interior layers. So in a real-world application, composite laminates are subjected to. Multiple damage mechanisms due to transverse impacts. And a component of failure that is a result of that is called mode one failure, which is essentially a separation of layers of the composite laminate. And so to study that, we wanted to do a pH test, which is essentially peeling apart a composite laminate to characterize the strength that, that takes. So my goal with this research is to characterize the field strengths of composites with different resins under extreme environmental conditions. To do this, first off, a composite laminate needs to be fabricated. The way we did this was using vacuum assisted resin transfer molding. And we created a composite laminate with and without a thermoplastic polyurethane interlayer. For each type of resin we're studying. And the interlayer is a key aspect of the research because it's been known and shown to increase the field strength in other composite laminates. So then, after it's created, a peel test is conducted to compare the residence strengths at 76 degrees Celsius, negative 55 degrees Celsius, room temperature, and under and accelerated aging condition. And as you can see in the top right, the test yielded some interesting results as the interlayer proved to be actually ineffective at extreme temperatures, which has not been studied before. And to understand the results from a technical perspective, I also analyze failure surfaces. And as you can see in the bottom right there, to failure modes which are very distinct that occur at extreme temperatures. And if you have any more questions, please come to my breakout room. Thank you guys. So next president that is Dylan Huang. Hello everyone. My name is still at Huang and I am a chemical engineering major. I first heard about SCCM. I believe my department advisors sent out department-wide email and I responded. And I really enjoyed learning how to use different types of equipment throughout the summer. So the summer I did my research on S2 fibers and tracking their tensile strength through a chemical vapor deposition process. And we primarily focused on S2 class because they're used in the production of armor composites for the US Army. And from my advisor's previous research talk, I found that the deposition of three amino appropriate time methoxy slightly and 30k listed oxy propyl try methoxy Signing, also known as EPS and GPS, can improve February adhesion between the fiber and epoxy, a composite matrix by increasing their interfacial shear strength, which you can see in the graph below. However, it was also important to us to ensure that the deposition fibers were compromised with preparation process. So by looking at each stage of the cleaning and deposition process, we can really pick out and explore how each step impacts the 10 self-serving and fiber strength of that to class. So in order to test as to class, we developed a to thes eats that process. On that first involved Washington fibers and cleaning. Turn to remove the protective cluster including on specific fiber that we use. And after that, it will be placed in a chemical vapor deposition chamber where thin layers of APS and GPS would be deposited. And after the preparation pod says, We would then take it over and start tensile testing, which would involve separating individual fibers and then placing them in primi trace. So we could load them into especially designed a machine called a dye strong tensile tester to generate ten style data and determine what was the next force and therefore the strength that each fiber can experience. So in the end, was there significant change a string? So we're, where would this change occur? To find out more, I hope to see you all in one breakout room later today where we can discuss my results and what implications that might have. Thank you. Thank you, Dylan. So next, destroy you presenting cells or smartphone as a glass fiber, a map, our deposit get silane. Hello, my name is Josh for you. I'm going to come up Engineering junior at the University of Delaware. Heard about SCCM through an e-mail this summer I worked with when he talked about a and Two team members, Dunhuang and James Tolman, on characterizing the surface morphology of S2 last fibers with vapor deposited silence. So as previously discussed, our group made our group looked at fibers that have chemical vapor deposited silence on the osteoblast. And my job was to ensure received the changes that this process had on the surface morphology of the fiber as this changes the interfacial shear strength and the interface properties. So I used an AFM atomic force microscope, which is the way that it works is sort of described in that picture right there. And using that we characterize 500 nanometers square sections and looked at surface roughness and as well as certain peak count, which is defined as features counter. So to see how the fiber surfaces effect by CVD and what affects the different wall times and the different the two different CG-islands have on the surface morphology. You'll have to come to my poster. Thank you. Joshua saw how about autonomic and present as shuns in this session. And I'd like to thank our president to president. Excellent works. I hope they enjoyed their water SCCM and the knowledge or experience that they have gained while working at CCM will be valuable and helpful in get KDI incoming base. And I'd also like to thank all the participants who attended in this session. So right now our plan is to see the poster in the breakout room in details, I ask all the presenters present bit in this, I'm going to go their respective Breakout Room 2 indirectly the audience and checking the start in details. For that more than half an hour, that will be a Google link to evaluate the posters. So please don't forget to evaluate the posters that we attend to our last session, which will be chaired by Dr. Jodi said. So thank you for attending this session and I'll see you later in the main room after about half an hour. Thank you. Yes, we'll get the show on the road. My name's Joe diesel. I'll be chairing the final session of the summers students symposium. I say I've been really impressed and really enjoying presentations that have gotten so far in talking with you guys. Gentlemen and ladies in the breakout sessions. Want to share my screen here in a we will get started. The everybody see the screen. I'm not sure what your C ES think I didn't make it big ash is. Okay. So just to check out, there were a couple of technical issues and I wanted to see if there were things going is rail in here. Where did she have to go to word? Hi, this is Patrick Mensa railing. It's in an internship or not. I had that something came up with her her workplace that's to sign up and was trying to change at time. Okay. That's fine. I just I'm just checking. Yeah. And then the other question was, is Shelby Turner she had been able to log on. I know she was having some computer troubles. Oh, well, okay. Thank you. Go Oh, go ahead. So the first we'll just follow the same format that we've done in the other sessions. The first person to speak will be Alice and Hecht. And she's going to talk about gumbo, fluorescent probes in shape memory, self-healing polymers. Hi everyone. I'm Alice intact. I'm a sophomore majoring and biochemistry at Louisiana State University. And my poster is on gunboats as fluorescent probes and shape memory self-healing polymers. And what combos are basically groups of uniform materials based on organic salts there in the solid state variance of ionic liquids, which we used in order to make fluorophores, which were then pressed into films. A lot of the times to test for mechanical damage in polymers, it requires expensive, bulky equipment. So what we tried to do was actually inject polymers with fluorescent probes in order to see if we could detect damage that way, which would offer a more economical way of testing mechanical damage. So how we did this? We melted the polymer first. We use silent 8940, which is a known ionomer. We then added the fluorophores to them, let it cool, and then press them into films. And as we can see in the results and discussion, we were able to successfully add the fluorophores to the polymers in order to get fluorescence. And for the N ions Betty and MTF to use, we were also able to get phosphorescence. Think you if you have any questions or want to know more, please join my breakout room. Thank you. Thank you very much else and we will look so railings, not going be able to attend. My whole spoke already. So that will move us to Chase Robinson, who's going to talk about devaluation of UV curable 3D printing. Resident is carbon nanotubes. Everyone does. Everyone see my screen and background and everything good. All right. My name is Chase Penny Robinson. I'm a rising senior at Southern University. Quantity Zoom now, I apologize for that. There we go. Hello everyone. My name is Chase Robinson. I'm a rising senior at Southern University. And this is my research about mixing carbon nanotubes out of a 3D printing arisen. So add in manufacturing is a new method of production, has become very popular in digital light processing is a method of 3D printing that uses UV lights, harden a UV sensitive layer or UV sensitive resonant layer by layer. Problem with BOB printed components, that they're weak and brittle. We can hold them weekend. Good for visualization. But as far as functionality, DLP prints are not there. So we are trying to improve the mechanical properties by adding carbon nanotubes, pretty much kind of like steel and are still rebar in concrete. Concrete is very brittle material. Steel rebar has that ductility. Hey, combining the two improves the mechanical properties of both of them and increases the applications for both of them. So we mechanically makes the CFCs and the resin by ultrasound application and then attempted prints using an unmodified any cubic photon mono. We did not have successful prints. The CNC resin needs to be modified, says successful prints the residents to biscuits to be printed because of the additional b, c and t is. So we are working on finding a resident, solve it back good be added to decrease the viscosity. And that is where we're at. Thank you. Thank you very much. Next up we're going to talk about the development of 3D printable smart polymer concrete. Is the speaker here. It looks like he is connected. Now, are you able to get the presentation? Yes, I'm ready to take it away. Can you see me? Yeah. You're good way. Louisiana State University. I first heard about SCCM for my advisor. He encouraged me to present my research here today that I did because I played a lot this summer and I'm excited to be talking about him. And my research is on the development of 3D printable smart polymer concrete. So think that company is currently the standard material used for construction in pavements, bridges, and runways, and access. That water is added to the mixture to make it easier to work with. However, this excess water, excessive water, it can greatly reduce the compressive strength of concrete will also causing dry shrinkage, cracking. And Paul, my concrete closes this advantages, the conventional cement concrete, because they can't be produced in a shorter amount of time and endow the concrete with high bunny shape. This study aims to develop a new polymer concrete that is high in bending shape, which is required for thinly repairs. Fire retard it. Sustainable, which uses solid waste recycling such as class and compatible with 3D printer. Photo curable monomer or doing a shade or a glass, aggregates were mixed together to create the mixture. Besides, it was only add it to improve workability. And after that, make sure it was compressed into a bowl. The samples were exposed to UV lighting to pamphlet during the Tesla test, compressions, as in three-point bending tests, were conducted on specimens that determined and mechanical strength. After mechanical testing, it was determined that the 50 percent polymer content with an additional 10 percent plasticizer. What's the optimal formulation? This formulation, attack and political empire, polymeric content. This is an important characteristic for repairs. The polymer concrete showcase promising fire retardants, even zones. And further research is being done to make this my polymer boy who had about whether a great painting. Thank you for listening and I hope to see and pause presentation. Thank you very much. Next up is John Coughlin, who he's going to talk about sinusoidal SMAC, pin laminate, bit drummer composites for impact, mitigation and be lamination and self-healing. Thank you very much. Good morning everyone. My name is John Kohler. I head off this conference through my advice and go shallowly. And today I'll be talking now about how I'm Vikram as I used to help fiber reinforced composite laminates for the, um, the lamination healing and then also impact mitigation. So shape-memory polymers and February and false lemonades, or we use a lot in industry. We have them using satellite, especially most of the way done by nasa, contains a lot of shape-memory alloys are just like an all titanium alloys for space exploration. And the issue we, the issue we have with this kind of lameness out, the transverse strength are always weekend when there is an application result in catastrophic failure, brittle failure. So the approach we, we, we, we design was to use this victimize to help, um, glass fiber reinforced polymer composites to be able to heal the laminations when they are using service. So what we did was that we looked at SMA wires, we tension program them in, in, in at room temperature. We use them as transverse zipping in composite laminates. And what you see in E is the Apo, a palsy stage. And then in case the NO feeling at the end we notice that actually improve upon crack initiation and then limits crack propagation and as a result, make a selfie level polymer which can be use in space exploration where we don't need to do healing. And I'm owing by just pass an electrical signal equal, achieve healing for e-comm usage in and now eliminate. So I'm basically, there's a lot about this week and I'll appreciate if we journey my breakout session to give more detailed explanation about this ongoing work. Thank you very much. Thank you very much, John, for your presentation. Next up is Laura. She's going to talk about developing a framework for estimating the material operating limits of epoxies. All my name is Laura Kitchener. I'm a rising junior and mechanical engineering department here at UT. In a high level overview, my research that I'll be discussing is actually on characterizing materials, repent bulletproof materials. To provide an introduction on what materials you're using. Composites offer a high specific strength and stiffness with pi, energy absorbing capability. And this is why they're very popular in armor applications. Through my research, I'm aiming to classify composites, durability, how temperature influences its properties. And finally, estimate the material operating limit of the epoxy resins within the composites. For our experimental setup that we've been using throughout the testing, different environmental factors that these composites are subjected to. We wanted to replicate. So compression testing of the neat epoxy resins was performed in a temperature range of negative 55 see to 95 say with different conditions, samples that were conditioned in 76 c and 85 percent relative humidity. So a pretty extreme environment. Some of the first results that we were gaining from these conditions samples. Once we put them in the environmental chamber, we wanted to see how the weight was going to increase as it stayed in the chamber. And you can see that it plateaus close to 3% weight gain, which is pretty important and would eventually show to have a negative impact on the material operating limit of both of the residence that we've been looking at and to discuss more about somebody's results when we're comparing the two epoxy resins that we've been looking at, there's a general trend of a decrease in the mechanical properties as the temperature increases in both. The main difference between the two resonance was observed around the glass transition temperature of the currently used resident EC50 in which is in black on the bottom right graph. You can see that it drops off after 55 see, because it's past its glass transition temperature at this point. And this proves to be a problem because since the mechanical properties are bailing very quickly within working range, it's not very feasible to be in use. And this is why we're testing a new epoxy resin audio RDC alongside it. So thank you for listening. I hope I've made you curious about my work and I hope to see you during our presentation. Thank you very much. Mixed up. Who's ever need Glia? Who's going to talk about additive manufacturing of great grenade long trouble aerial sensor platform. Thank you. So hi, my name is Evan to tag me. I'm from the Department of Electrical Engineering at the University of Delaware. I work in Pearson lab, which I believe is cohabited by the CCM and the ECE department. So that's why I've spent the last few summers. They're working on this, a grenade launcher, quadcopter drone. This project was inspired by an initiative from the army that's looking for 3D printed devices, for things like chemical sensors, which benefit from being disposable and easy to produce. Part of that initiative is looking specifically part grenade grounds, which are great for soldiers because they fit right into their existing equipment ecosystems. This drone is intended to provide long-range autonomists chemical sensing, with the added benefit over other drones of being able to penetrate foliage. It's been extremely fun to work on and it's led to some unique challenges in the really limited volume and form factor. As of last year, I was able to successfully launch the drone, have it recover into stable flight? And this summer I've mostly been focused on eliminating vibrational noise from the frame, which has been limiting how likely it is to survive recovery after launch. There's been a lot of really cool problem-solving involved in this project that I want to shove into this slide. So please, please feel free to visit my breakout room and ask questions or learn more about this. Thanks. Thank you very much of it. Next up this camera and Pepe, we're going to talk about material characterization of cold spray 3D printed copper parts. I saw my name's Cameron Papi, currently an undergrad senior at Southern Utah University. I will be graduating in December and a degree in mechanical engineering. I'm from this area and I kind of heard about CCNE and it's my first summer working as an intern, you learned a lot. One is Jake years to S1 and shake Robinson. I just finished up. I undergrad in mechanical engineering at the Virginia Military Institute. I've worked with LJ homes for the last three years. Kind of met, hey, you gave me the opportunity to do some research here. Now I'm going to start my graduate degree in mechanical engineering again, UD this fall. So the summer camera and I worked on characterizing some 3D printed parts that we're printing with cold spray. And this kinda cool because although cold sprays been around for a long time, so we can use as a coating technology. So an Australian company names SP3 D developed world's first commercially available, added a chain that uses cold spray to actually make parts. It's a relatively small company. There's only two machines in the US, and we'd have 1 over 1, which is pretty cool. So we've been helping them out all summer doing some characterization. Basically, we've been praying parts and trying to find the best post-processing parameters because the cold spray, the metal is cowork entire time. So it comes off. Machines are brittle. So because they're small, they were doing some of this characterization that they can't afford helping them now and then also apply some of that technology to or some of these findings to making parts for with DOD applications here in the US. On, so we write j cosine. We didn't really know. There's not a lot of data on post-processing and making products with sp3, the machine. So that's what we want to look into. So we create an experiment, basically a different nozzle temperatures and you can select from S0. We had different heat treatment temperatures of copper samples. So we use as copper samples than we wanted to basically measure the conductivity to see if the structure of these arts was pretty similar to like a pure piece of property that you can have. And we also looked at some tensile test data. We had to see if there's any correlation. There are results basically showed that throughout the process, the whole heat treatment and then machining of the arts, the results in a masterpiece has had an 85 to 90 percent conductivity. Or I want a piece of here happened we had so this time it's older, satyr is published and voids while using this process to me, hopper parts. In some higher temperatures. When we use higher temperatures heat treat. This was the voids were further evidenced by, you know, there's some bubbles and products in your machine and now you can see actual right, yeah. Expanded ERPO isn't at higher temperatures to David. Expand a lot and rupture. So now there's something you weren't quite sure because we never use like higher temperatures treated these products, right? Something that we're aware of now. We have data onto. So if you guys want to see all your data and the sum of the products we need. Some are just going to go. Thank you very much, camera and Jake, and I believe this concludes the speakers for this session. So I think the next step is to go to the breakout rooms, which Kristen is just inviting everybody to. Everybody go and have fun talking with the presenters. I'd like to thank all the presenters today. And we'll reconvene in about a half hour. So everyone. Welcome back. And while we're tallying up the scores before we announce them, I think we're going to want to introduce Professor Eric said hose, but it'll tell you about other fun things you can do with composites. And after his talk, we will amongst fuel once floor is all yours. Thank you, Suresh. And and you know, I'd like to thank everyone. I've I've been able to join a view of the poster sessions. And I thought it similarly presentations were truly great. So I'd like to mention, so I guess I want to spend a few minutes when we're tallying up the votes to talk about something that is quite dear to my heart, as is a professional society called cAMP stands for the Society for the Advancement of material and process engineering. And I have been a member, actually of sampling you since I was a freshman in college, which is longer ago than I care to remember about. The, you know, it's really a great professional society. And I encourage everyone to become involved. It's really, I think, the composites Professional Society of the United States. And so I have a quick presentation. I am recently became the faculty advisor for the sappy student chapter at the university at hour. And I encourage everyone to another, many from other universities. But cAMP has a wonderful student programs. And I want to tell you a little bit about it, but I have a special invitation for those who are university at our students. If you're a university at our student and CCM in turn, of course, as, as first steps, I invite you to become a full member of the society and participate and our local chapter activities. And also we will pay for your first year of membership. And when you graduate, Sam P also will give you a free year of professional membership. So I will be sending out an e-mail. I'm going to get from Christian, everyone's e-mail address. So I'll send out an email with more information that you can send an anion so that we can get you ready assured. And I hope that you'll purchase hay. Also lobby. So this is a so let me share my screen. Okay. So hopefully everyone can see the presentation. This was a presentation that was put together a few years ago to reach out to students to encourage them to participate in Chapter activities. So cAMP again, Society for the Advancement of material and process engineering. University of Delaware has had a student chapter for a very long time, back into the 1970s. I think there's a lot of things that are beneficial about joining a professional society, professional development, and in particular, networking and going to conferences, going to local chapter meetings. You know, building your professional network is I think critical for having a building your career and really career advancement. And those who I've seen her involved with cAMP have often gotten internships and jobs directly from some of these networking. We also, sappy also has several international design and build competitions. Typically every year we send about ten students to the symposium, an exhibition which occurs in the spring. And the symposium and exhibition that's a huge trade show as well as a technical symposium. Add at this trade show on the floor or the trade show, there is a ultra lightweight bridge contest. And you design and build the bridge. You can use the facilities here at the center and go out there and it's a lot of fun. And the conference itself is a lot of fun. As I mentioned, professional development is not only in being involved with national sappy, but local Baltimore, Washington chapter. I also happened to be Vice Chair for Student Affairs for the Baltimore Washington chapter, which is our local chapter. But on-campus we've had a number of guest speaker advents. People from DuPont, Northrop, Grumman, and more, as well as industry, tourist, value ribbon and L's and that's Albania. There are other places including boeing and gore, ILC, Dover, and dog fish had which I think is process engineering at its finest. Not just come August I guess, but, but again, there are also workshops and things of that nature. So the key, as I add, I think in my own experience is the opportunity for networking, meeting people in the field of composites and materials and processing. As I mentioned, we have the Baltimore, Washington sappy chapter is the parent chapter of the university at our add up every month. Oh, wow. At least pre COVID almost every month. There was a local chapter meeting that typically held in the Baltimore area and the cAMP student chapter subsidizes the travel. We typically just rent a van and drive down there, so there's no cost for that. And the Baltimore-Washington chapter subsidizes the meal so that, you know, It's typically just $5 for whatever is on the menu. And there's the technical talk or tour. And again, there's this big sappy conference and exposition. It was supposed to be in 2020 in Seattle and 2021 and Long Beach. And that is a judge pitcher out from actually several years ago from one of the receptions. It doesn't I guess that we loved composites is strategically placed over there. Whether a lot to not only do we like commodity, but there are plenty of beverages. As I mentioned, there's less competition, was called the ultra lightweight bridge contest. Basically, you design and build and test to come out of the beam. There's some pitchers on their aid of the manufacturing here and SCCM. So not only does it give you opportunity to get some experience in design, but you get hands-on experience doing Composites Manufacturing. And many of you have learned a lot of that here over the past six months. And these are just some of the results we did quite well in 2029, which was the last in-person conference, replace second and natural fiber. There's these beams and there are all these different categories. There were plans for 2020 in Seattle and 2021 in Long Beach. But I believe his back and Charlotte this year. So I would really like to get a group together if we are interested to compete. And these competitions and courts are also, in addition to competing their cash prizes. There's also an additive manufacturing competition. Basically, you design and build and we print these, you know, whatever your designs are and it's based on strength to weight and on Coursera cash prizes as well. In Baltimore, Washington sappy. We also did a local version of this, this year because most people were virtual. And Edition, we do some community outreach, Boy Scouts and Aerospace Academy camps that come to campus. And that's always fun too. So this is a picture on the right. Some of the leaders have Sant the, a couple of years ago and Charlotte, it's a great opportunity, become involved and network with people in the field. And I think this is really a great opportunity for students to build your network. And I kinda lays the foundation for future success. And of course, after kind of a gap here, when Earl offline, we're looking for plenty of liters. So president, vice president, treasurer, secretary, and others. And we really hope you're will become involved. And even if you're not at UT, I certainly encourage you to become involved their student chapters all over the country. I notice that there are many from southern and LSU here. And in fact, one of our, one of her about Baltimore, Washington members recently became faculty at LSU. Andrew back now I encourage you to contact him, were encouraging him to started student chapter there, which will actually be affiliated with Baltimore, Washington. So again, you can contact me directly, Eric, here and see Sam. And what I would do want to mention one of the projects that and this is a direct outgrowth. Kind of behind me. Look, we have this sum. This is a composite weight or this was manufactured as a sappy project. You see this API? Sorry, this API logo, demanding it at a manufacturer as a project a few years ago. I also lead, this is an independent study. So the students who also did this, it was kind of a many, many senior design who are affiliated with sappy. They also about credit, course, credit for producing these. And I agree to do this just so long as I got one of the final finished wake board saw, we made about six cities that we've tested them out on record with bags. So again, if you have any questions or would like to talk more about cAMP, you'll be getting an e-mail from me, all the University of Alabama members. But even if you're not at the university at our, I think cAMP is one of the wonderful technical societies to become involved with. Especially if you're involved in composites. And I guess with that, I'm happy to take a few questions. But hopefully we've also had some time to tally up the winners for today. So any questions for Eric? This is the time to ask if you have any. So Eric, can you tell them a little bit about what kind of projects MP has students have done and the fact that they may well, when we are allowed to travel, that they've been to actually some of these meetings here. So the cAMP actually sets aside at era models funds from their membership every year to support student programs. And locally and I organized a symposium for those who are doing research. We have local students symposium. And there are both poster presentations very much like you did today. And we've held it virtually for the past few years. And I'll also podium presentations where you get up and you speak and present your research. There are prizes, cash prizes for all of those. And the winners of those are selected as finalist for the National Symposium. And the National Symposium, if you're a finalist for that, you travel. Sappy pays all of your expenses you travel to present your research. And the winner of that, and I was a winner many years ago. As a PhD student, I, the winner of the THC symposium, gets an expenses paid trip to either Europe or Japan to present their research when all the SAP is not just a US technical society, but it's global. So in addition to that, there's also the design competitions, as I mentioned, the wing in Bridge competitions. Sappy also provides funding for the local chapters. So every year we write a proposal to get funding that helps to defray the cost of travel and participate. And it's, it's a, it's a wonderful opportunity I think, to not only, you know, it, have a good time at a conference, but also build your professional network and cAMP. Even actually at the symposia. Sappy has a lot to young professionals. Meetings that, you know, in an increased networking among people who are young. And then also there's the reception and which I've kinda elbow my way into a few times. So I guess at what that Abby, That's it. It's essay. There's a lot of opportunities. And for example, I have had students buy on students who are undergraduate interns who participated, who went to sappy, got internships at that SpaceX, Tesla, and blue origin. So there are a lot of these, especially aerospace companies, are very involved with savvy. Okay, great. So far, I want to say that everybody did a great job of presentation considering we were doing it online. I think I went visited some of you guys with your posters. It was actually not a bad experience. You kind of get to talk to you, contract to everybody, but at least the ones I went and talked to, it was very nice to come to know what they've been doing and so forth. So there are some things that work well. But first thing is all of you did really well. This is just like a fun thing where you guys get to work. And so in some sense, we are all, you are all winners. But this is just for fun, as I said. And voting was very close, but this is how it worked out in the end. Okay? Our third place tie winner is even. But glia, so on the additive manufacturing of grenade launcher, PBL, aerial sensor platforms. So congratulation, Evan, and you can all give them an applause if you want to unmute yourself and do that. So and we had a tie for the third place. Or Henry fill lowers our first speaker from the first session. So he tied with evidence. So congratulations Henry. As second place. A body is the Lord Kitchener who talked about the limits of epoxy resin. So congratulations. Let's give her a big hand to and our first place. And goes to Edwin Rivera on innovative textile based for a finger motion recognition. So I guess this was a very cool project that everybody could understand. So I think also very forward-looking. So congratulations Edwin. So again, as I said, you know, everybody did a great job. Usually we would have I don't lunch served for you guys at the CCM, but maybe next year we'll do that again. But I don't know if anybody else has any, any last comments. But this has been a wonderful, wonderful presentations by on a few really good work. And hopefully this will all encourage you to go into graduate schools and higher studies and will whet your appetite for that. You're hoping. Any any last-minute comments anybody has. And we just like to ask our partners to share here so you can get a screenshot. I'll, I'll be in touch with you. It's all spacing to make some arrangements to avoid stealing, takes pictures, what your voice a lesson, that's great. Okay, so maybe you don't. Thank you everyone. You guys can go and have your lunch now. And except for the award winners, please hang on so they can take with you pictures and tell you, give you some either direct or other such directions as to what to do next. A great job again. You get 10 football. Have a great rest of the summer.
