Making ballistic armor with UHMWPE and ceramic tiles.
Correction from the narrative in the video: I bought 170 gram/sq meter UHMWPE, not 160, and the roll is 10 meters long. Total cost of the roll, tax/shipping, was $135. Not too bad, actually, since the roll provides enough PE for at least 3, if not 4 plates.
As I've been working on the test plate to actually fire upon, I've found that I have probably got overkill on the number of layers I have in this plate. With this PE sheet, 33 layers is what it takes to make Level IIIA armor capable of stopping up to a .44 magnum. My test plate is 45 layers which makes for ~3/4" thick plate. THIS chest plate is about 56 layers and is nearly 1 inch already.
The tiles in this video are 6 mm thick. I may change out for 8 mm tiles instead after testing the small test plate.

Look into vacuum bagging. At least in carbon fiber parts, the weight is in the resin and vacuum bagging gets much more resin out while also increasing overall strength.

@bobojo37 3 года назад

I've seen impressive creations of carbon fiber made this way.

Awesome. I eagerly await your results...for true 3+ rating, I heavily encourage you to also test m855, as it is famously difficult to stop.

@BooDamnHoo 4 года назад

That would be difficult. I don't own any. 223 rifles.

@@BooDamnHoo I've had a similar problem before in testing cal's I don't have, I just ask around locally, typically works lol

@BooDamnHoo 4 года назад

@@floridianzach2277 If it works with 308 then I'd probably have to make another test square for that and all around a local gun range. One of my neighbors may have one (probably) but I might have to buy m855 just for purpose. Not sure they'd have that in their stocks.

@cjf-rw8vl 4 года назад

Please tell us the barrel lengths of the test rifles when you get to that point. Also it’s exiting to see an actual UHMWPE homebrew plate!

@BooDamnHoo 4 года назад

The rifle will have a 16.24" barrel. I'll even measure muzzle velocity so barrel length will be irrelevant.

@BooDamnHoo 4 года назад

Also...I will be following (as much as possible) NIJ standards when I test the plate. I will place the test plate against a wood backing. I will set a chronograph 2.5 meters from the plate. I will fire from 15 meters (49 ft) using actual 7.62 NATO FMJ ammo. The only thing I will lack is NIJ test standards have modeling clay between the ballistic plate target and the wood backstop. I don't have any on hand and will just place a square foam pad behind the plate. I won't get any back-face deformation info but I will at least be able to see whether or not the plate stops bullet penetration.

@BooDamnHoo 4 года назад

Addendum: I will be testing my test armor tomorrow (Saturday, 12 Sep), weather permitting. I am going to test from 10 meters instead of 15. I will also just measure muzzle velocity rather than set the chronograph 2.5 meters from the target plate. I am a bit fearful of debris or the plate flying back and damaging my chronograph so I won't set it up that way. At 10 meters, the muzzle velocity will be essentially equal to the velocity at impact so getting the velocity close to the target should be irrelevant.

@Techthisoutmeow 4 года назад

Well done! i'm currently working on my own curved and multi curved mold, I can't wait to see how your tests go. That UHMWPE is something else man, I've only used it a few times in builds and each time I've been blown away by it's performance. what resin are you planning on using?

@BooDamnHoo 4 года назад

The current plate is just standard fiberglass resin. I'm debating how I want to attach the ceramic. Originally I was just going to use the same resin but then caught some of your vids on trying to extend the durability of ceramic. I've also been considering using one of the construction adhesives to attach but then mud in the seams and covering the tiles with some resin mixed with a LOT of SiO rock polishing grit to the consistency of mortar or cement. Maybe derive a little extra protection that way, especially at the seams?

@BooDamnHoo 3 года назад

@Kalergi is trash I'll have to try this. It would save a lot of weight.

@mareka7 7 месяцев назад

Slightly different application, but.. do you think that will it be suitable as an additional layer under an inflatable mattress, which should protect against punctures by an acacia thorn, a cactus or a needle? How many layers would this need?

@BooDamnHoo 7 месяцев назад

I suppose if you applied the layers to the mattress with flexible glue it might work (maybe 3 layers, max would be fine?). There are, perhaps, better versions of the PE to use that way as well: the type used for stab-proof clothing. It is more fabric-like. Kevlar would probably work too (easy to get on Amazon or eBay: it has a yellow color and is heavy like a denier nylon. In fact, you could get a roll of denier heavy nylon and just make a double or triple layer sheet with it and use it underneath and on top of the mattress.

@nateb4543 3 года назад

Cool stuff! Have you considered overlapping the tiles so there isn't room for bullets to slip between? You've got to record in landscape, quality will be so much higher

@BooDamnHoo 3 года назад

I've corrected the landscape issue. Won't do portrait anymore.

@nateb4543 3 года назад

@@BooDamnHoo I'm sure you figured that out on your own. Have you ever watched anything from Tech this out meow (posted a link at the bottom of the comments) or from this guy? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PcLd4h095DQ.html I'd love to see a collaboration

@BooDamnHoo 3 года назад

To overlap tiles means a double layer of tiles. That means a LOT more weight and a lot thicker, or corresponding fewer UHMWPE layers. The tiles are butted up to each other as tight as possible and the small gap filled with resin. A bullet striking directly on a seam will wreck two tiles but still be distorted and shredded by the tiles. In one of my shots at a test plate one of my rounds did hit a seam. It was still stopped from penetrating the armor.

@piotrjasielski Год назад

You could iron the sheets to bond them together. This way you'd loose a lot of weight due to resin.

@BooDamnHoo Год назад

I went forward and did that on my next plate. It is VASTLY superior in every way to iron the sheets together.

@bryanrosario4954 3 года назад

Friend. Could you replicate the artisan armor made with $ 30 dollars from the ZNA Produtions channel?

@BooDamnHoo 3 года назад

Say what? I am currently having to wait before I spill for another roll of UHMWPE, at which time I intend to make a full plate using my new ironing method instead of resin. I am having to balance out purchases right now between stocking up on ammo, powder, and holsters. I'm also waiting for parts for a gun build I'm doing. The new plate sits somewhere in the middle of all that (because it is looking like I may actually need the armor sooner rather than later).

@bryanrosario4954 3 года назад

@@BooDamnHoo In that case, I'll wait until you have the time and resources to replicate the armor from ZNA Produtions. Good luck with your projects.

@BooDamnHoo 3 года назад

@@bryanrosario4954 I see what you mean now. You mean the simple fiberglass armor he made. It was that video and those of Tech Me Out Meow that inspired me to go for it, but using UHMWPE instead. Yes, fiberglass can be used and you could cover it with ceramic tile to increase its ballistic protective performance, but it is heavier than PE and I wanted to avoid the possibility of glass fibers going airborne and into my lungs (or even glass fibers entering the body from a penetrating bullet). Now that I know a simple iron can make a solid PE sheet plate (that by itself will stop pistol rounds), and can easily be bumped up to stop rifles, that's my go-to now. Ironing sheets together saves a TON of weight. Fiberglass requires resin by nature so will be heavier before adding tiles.

@sinasaman3224 Год назад

does it produce fragmentation please ?

@BooDamnHoo Год назад

Do you mean the ceramic? The tiles haven't fragmented all over the place - it was all contained within the covering of duct tape that I used on the test plate. On previous tests fragments we're contained inside the ripstop nylon cover I had on it. I do not believe that fragmentation is a problem with tiles. The bullets flatten and a bit of fragmentation of them in the plate are contained as well.
