Default home made body armor how to?



Advertise Here

I have had an idea good or bad if you took a german flak vest put a layer of titanium in between two chunks of kevlar.I did see the test pic that some one else showed but would love to try to make something that could take rifle fire that would be bad ass.I have though of about 1/5 inch thick titanium plate in between two kevlar sheets don't have the money now.Next question is this legal?If anyone has more info please share.The metals i was thinking of titanium/vandium alloy (aircraft engine parts are made of) maybe some aluminuim on top of titanium between two chunks of kevlar.

MythBuster did a thing on this. What they found out was ceramic tiles put together with some epoxy stopped everyhtin except a 12 ga slug. I think the tile he used was the sheets of 1 in tiles for like a bathroom wall. A couple layers of that and some epoxy and its good. I know its not the best, but it could be better than nothin.

They encased the tiles in high strength, gypsum reinforced concrete.

Default If it were me and

I had to do SOMETHING to protect myself and store bought vests werent an option.

I would get as many yards of spectra/vectran as I could and layer them so that the weave is 15degrees away from one another. the more layers the better. I would sew in full steel plate sandwiching all layers but for a couple on the inside and the outside.

Very thin stuff and very lightweight. I'd probably include a reasonably thick layer of rubber too for impact absorbtion and spread.

This idea originally comes from 2500BC china as they would layer leather and silk together with the weaves offset from one another to protect against crossbow bolts/arrows.
As long as epoxy didnt degrade the spectra/vectran Id epoxy the layers together. Anything to slow down and spread the impact across the whole chest rather than pinpoint.

Default The outside layer should probably be

thick tread steel belted radial now that i think about it. You want to be able to slow down the bullet and spread the load across the chest.

thick rubber with lots of ridges internally and steel belts goes a long way.

The spectra vectran layers also provide a great deal of stab protection.

Now remember Im merely surmising that this will work. Please test in advance of wearing and dont wear your test model after it has been tested upon. In fact dont wear it period and just purchase a vest.

Im merely guessing with this and have no empirical data to back up my guesses.

Please dont get a Darwin award and then blame me. Not my problem. I'm merely guessing this might work.

Finally, make sure you error on testing more layers rather than less or just buy a vest.

Buy the vest. Dont be stupid. Do this for mere research, something fun to learn about ONLY ONLY ONLY ONLY. DO NOT WEAR YOUR HOMEMADE VEST!!!!!!!!!!!!!!!!

Go for it! All body armor really is is just hard metals inserted into layers of a vest. You can comission for sheets of titanium or steel to be made to fit whatever size you need and then buy a vest to insert your body armor into. I don't know how you would cover the face, and the arms would be problematic to figure out how to cover....

Another body armor design is scales, large circles of material overlapping each other to form a few layers of body armor. One version, 'Dragon Skin' is amazingly pliable. Though its effectiveness dwindles in heat.

Default fiber glass

layers of fiberglass will act in a very similar way to Kevlar. I would also buy a full chest plate of AR steel or titanium.backed with carpet padding.(home depot, lowes)(not the cheap stuff).use heavy cotton jeans material for the outer shell.(can be bought at wall mart or fabric store.)
I have already built and tested against a 44 mag.
gets to about the fifth-sixth layer and stops cold(10 layers of glass). thanks to my mother who is a very good sower

It will be cheaper to buy a sapi plate than try and buy a titanium sheet. It is very expensive and hard to cut and bend.May look at bullet proof plastics.

titanium is very flexable, it would transmit the energy to what ever is behind it.

Titanium would be great, but it is really expensive. A 12" x 12" sheet at only 0.10" thick (that's 1/10th of an inch) would probably cost you nearly $100. Take that times two (you don't want to get shot in the back do you?) and you've spent $200 just for the metal. For another $100 you can get a real Level IIIA vest brand-new. Plus it is a REAL b!tch to cut and bend, that stuff is crazy strong.

I've considered sewing my own just for experimentation to see if it could be done cheaply. You can buy ballistic kevlar by the yard online from various sources or from eBay, just make sure it's the ballistic kind. There are many other kevlar/carbon-fiber weaves out there for upholstery and such that are definitely not suitable for bulletproof vests, at least not without layering them 5" thick.

I would start there -- buy a few yards of ballistic kevlar, do some research to determine how many layers are typically used to stop different type of threats and go from there. Soft armor manufacturers shoot the vests against a block of clay so they can see what the impact is like for the person wearing it.

Test anything you may make with the 7.62 X 39 Rounds , specially russian steel core, Wolf or Brown Bear, if it holds you have a good Vest.

I'm actually willing to try this. . . I think this is something that can work.

If I end up putting together something, I will take a video of it and post it up here.

One suggestion. Stay away from places where bullets are flying.

In regards to the video. Just a FYI. The vest being shot is a flak jacket not to be confused with body armor. Flak jackets are made to protect from minor shrapnel. Not full impact rounds. Hence the failure is expected.

Body armor with ceramic plates will stop the round used in the video.

I highly suggest that no one wear a flak jacket as a bullet proof vest. They will be highly disappointed in the results.
