Check with some plastic companies, they may know how to make a more dense recipe for plastic,that surpasses the milk carton plastic and make plates for you , if your tests show promising,you could sell the heck out of them and after the initial start up cost,the parts for you,would be relatively cheap.

1. This is awesome! Really appreciate this. 2. I have a suggestion for your fabrication process with the composites. Instead of casting solid blocks of HDPE how about this. Separate the softened HDPE into 4-8 equal sized portions. Lay down the first portion and compress enough to form it to the mold. Then add a layer of fiberglass, then another layer of HDPE, layer of fiberglass, layer of HDPE, and so on. Put it back in the oven as necessary to maintain flexibility. After you've gotten however many layers you decide to make, put it back under compression (likely with weights that are heat resistant) and then heat the mold up to near melting point. Then go forward with the annealing process. With the composite sandwiched between HDPE the individual fibers motion is also constrained by the HDPE and the HDPE flow under impact forces is constrained by the composite fibers. Just an idea.

Yea I was thinking the same thing! I believe that the benefit from doing this is that when the bullet enters, there is that property that the HDPE has where it absorbs the energy really well, and is extremely durable. With that in mind, the layerings of fibreglass act as the part of the plate that will actually catch the bullet, allowing the energy to be spread out Better, and allow the HDPE to catch the bullet much better, creating more resistance for the bullet. Now if you added a steel plate (designed to fail, for reasons I am about to explain) placed in front that will slow down the bullet, allowing our HDPE/fibreglass composite plate to catch the now considerably slower bullet efficiently.

A counter is a mosiac, however, this leaves cracks between the tiles, and you've witnessed first hand what cracks between materials can result in. A simple solution is a double layer of ceramics offset in tessellation, but that forces you to use double the ceramic needed. I think a better solution is out there, and can likely be cooked up in the discord (when you give us the link, lol). Edit: 20:16 There is a commercially available level 3 plate (AMI something) that is non ceramic that uses dynemma backer with 3mm steel in FRONT.

Carbon fiber is pretty strong stuff. Maybe that could be incorporated in somehow…?

This is truly ingenious, fantastic video, I started cutting up milk jugs, melting plastic grocery bags, chemical bottles, shampoo bottles etc into confetti. I ended up getting a cheap toaster oven to melt it down and made a 5×8 wood mold to press it in to make small individual plates for a batman armor suit and so far I've tried doing thin layers at a time of hdpe and putting fiberglass tape in between each layer of hdpe and change the direction of the fiberglass tape each time until the hdpe/fiberglass is a half an inch to 3/4 of an inch, I think that the fiberglass tape would work best in between the hdpe layers because the fiberglass strands are far apart so the hdpe can go through it and bond to itself better than fiberglass fabric since the hdpe can't melt into a liquid like epoxy resin does. Then I will try the annealing but not sure what temperature will work, I looked up a couple sites and one site said to anneal hdpe at 200 degrees for 2 to 4 hours and the other site said 250 degrees at 2 to 4 hours which I think might be to hot since hdpe melts right around that temperature and lower the temperature slowly after that between 10 to 50 degrees per hour, I'll try to figure it out as well, I won't be able to test it however where I live, I can't wait to see how your annealed hdpe plates stand up against hand gun rounds or rifle rounds etc. Ps I'd love to see you try what I'm doing with layers of fiberglass tape in between the hdpe.

I see lots of potential. Try making several thinner layers and sandwich several of them with wire mesh between each layer; then heat it up and compress the whole thing so the mesh layers are embedded in the plastic. You could also add some steel wool between each mesh layer; I think this will considerably add to the stopping power because as a bullet pushes through the mesh, the mesh (and steel wool) will pull the plastic tighter around the bullet as well as help hold the plastic together.

Try encasing the ceramic and steel within the hdpe to help hold the ceramic together. It would also be interesting to see how layering the materials within each other in various thickness effects the ability of the plates to stop projectiles.

Couple of thoughts- Cut some of that glass into strips and incorporate it into the HDPE when molding it. That way the glass will basically create small pockets of restrained plastic that can't move out of the bullets' way as easily. In other words put the added strength of the glass inside the HDPE instead of outside. With sufficient pressure the HDPE should penetrate the glass cloth and bond it all together. HDPE (like most thermoplastics doesn't "melt" the way say ice does. It has a "fusion temperature" (look it up) slightly above 400F depending on its exact composition. Commercial processing is done at about 420- 430F to get best homogeneity and crosslinking which increases strength. Yes, it's harder to handle at that temperature but you can also pour it into molds like syrup instead of kneading it like dough. That means you can make fiberglass "lasagna" out of it- a layer of glass cloth, a layer of HDPE, repeat until the mold is full. Mild steel plates would be better on the front than on the back IMO. Bullets lose more energy penetrating that than they do HDPE so it would be better to decelerate them rapidly with the steel, then let the plastic do the relatively easy part of catching them.

Basically “UHMWPE at home”.😂😂 Good work dude really cool video

If you are not doing this already, your best bet at stopping any bullet is to put the ceramic or metal plate as the first layer in this ballistic protection system you are creating. The reason for this is you want to break up the bullet or make it fragment upon impact with a hard surface. The plastic will deform (plastic deformation vs elastic deformation) and absorb some of the kinetic energy of the projectile. The problem you will face in using low thermal plastics is the kinetic energy of high velocity rounds tend to 'melt' there way thru plastic barriers that have a low melting point, kind of like a hot knife thru butter. The problem with using ceramics, for bullet fragmenting, is they tend to shatter like glass after the first round hits them and therefore drastically reduce their effectiveness at shattering successive rounds. The fiberglass wrap you are using is really good idea for spall containment. Lastly, the best material I know of for fragmenting high velocity bullets is high carbon steel, but this ways a ton so to speak. Love the video and project you have going on, godspeed in your endeavors.

WITH THAT SAID...Did I unconsciously heat it longer...Hotter...cool it slower...press it tighter ?? ...I wasnt very Scientific in my process...as far as repeating exact steps. That;s one reason I posted what I found. I hoped others would chime in with their findings. Wish I had a warming/cooling box like his...I think cooling too fast hurts it.

@@bubbaonpc how long would you heat it and how would you cool it slower? Reduce the oven temp I assume? And how many gallons of milk would you use at a time?

Have you thought about laminating layers of the hdpe rather than melting it into a solid block? I know that some commercial level 4 plates are ceramic front with multiple layers of a ultra high density PE.

I was thinking the same thing. My research on commercially produced UHDPE plates revealed that they laminate about ten sheets together that then de-laminate on impact. The delamination absorbs even more energy from the bullet.

I've used UHMWPE fabric before, that stuff is wonderful. The bullet resistant Guy Fawkes mask that could stop shots from a magnum was made out of it. I don't know if they make a HDPE fabric, I know you can find thin films of it. So as far as laminating HDPE layers together I dont know if I could with just recycled plastic, but I'll look into it.

Yeah, UHMWPE is some crazy stuff. This was more of a test to see how well recycled HDPE could hold up, because it's one of the most produced plastics in the world. But there will be future builds with UHMWPE fabric and sheets!

@@Techthisoutmeow I'm thinking you could weld thin layers of hdpe together with a heat gun with fiberglass tape in between and the fiberglass tape has holes in it which should be enough to allow the hdpe to go through the fiberglass tape and bond to the layer of hdpe underneath the fiberglass tape. I'd love to see that tried.

That's great!!! Thanks for your research!!!

Thanks for making this video

If you pour the plastic into the fiberglass final form instead of building the fiberglass shell around the plastic, it might reduce the area the plastic can use in deformation and provide more stopping friction.

Awesome thank you. I have to say perhaps a sandwich of the plastic and kevlar say 5 layers with a thin hard steel plate at the back to catch the round after it has mushroomed and lost some energy. Appreciat the effort. Cheers.

Metal on the front should work better for mangling and slowing the bullet, and HDPE to catch that.

I think ceramic or porcelain is much harder and if 1 layer of fiberglass was assured to it with resin, most of the tile would probably stay in place

Really good stuff though, if your looking into fiberglass reinforcement I would go for some S-glass over E-glass or any other grades.

I retired from school district maintenance. We used and discarded 5/8" slabs of recycled milk jugs and oil bottles. Stopped most .22lr rounds and .38 special. Man, I miss being able to pull them out of the dumpster.

Used to work in a lab testing ppe for use by auto oems. You’re doing a good job figuring this out so far, the only thing i might suggest is to produce standardized test specimens for analysis before a material is destined for the range. Why? Firstly, and most importantly in this line of inquiry, is to ensure a sample’s homogeneity. Secondly, os the ease of testing will be improved, and the quality of data, will be improved by am order of magnitude. Thirdly, the cost of doing testing (in money and time) per data point can be brought down as your data gets better. A simple charpy/izod set up, density check, vacuum annealing oven, hot oil bath, etc could be had onn the cheap depending on your handiness amd luck in finding deals. That with some ingenuity with excel could give you repeatable results that will give insights into how the material responds to stresses and why, while also permitting the testing of additives (such as talc nylon fiberglass rubber etc) and novel manufacturing methods. Most of the astm/iso procedures, requirements, specifications, methods, etc are available online. These will give you a start on the how amd why of various tests you could perform.

I think HDPE would make a GREAT anti spall coating.

Great video!

Great stuff.

Very interesting. Greetings from France!

Very cool!

Came here back after some time when I saw the testvideo of your plate-collection from Taofledermaus. It is amazing how tough this material is. I experimented myself with armors for some time (not in that dimentions you do, but working with paper can have remarkable results) and read a lot about it. I have some suggestion, that may should work in my mind, but I have not yet seen realized in home made body armors: The hard material of the projectile has to break up to increase it's surface of spread it's energy. Ceramic is very hard and breaks and absorbs the incoming energy that way. Metall acts brittle or ductile depending on various situations. In tanks they use sandwich-armor, where a ceramic medium is placed thight between two metall plates. The ceramic tile breaks up, but stays more or less together by the metall front and backing. That prevents the brittle ceramic from exploding. (As you said, compression helps to keep the material together so it doesn't move out of the way too much. my idea would be: a ceramic tile, which is reinforced by some kind of resin and a surounding layer of fibre is glued between two sheets of metall. This can be backed with polyethylen to absorb energy and this is wrapped by fibre/resin, so it holds together. Some interesting additional notes: In early days of ceramic armor-developement, someone explored, that ceramic coated steel (emael coating) was more durable than the same steel without. Making emael was a quite common technic to make household metall corrosion resistant, so it should not be too complicated to use this technic for own purposes. Maybe a stag of thin steel sheets (easier to bend), which get coated and glued together could make an interesting core for polyethylen-armor. Observations of my own work with paper/glue/fabric-sandwiches gave me the conclusion, that changing layers of hard and elastic materials create objects, that can absorb much impact and penetration energy. I hope you can take some inspirations for your work. Greetings from Germany🙋
