i got paid so i'm gonna buy this kevlar/carbon fiber stuff to make one of my jackets bulletproof or stab proof or some shit do i just stitch it directly into my jacket or something? i know i have to use several layers of this fabric for this or the rounds/knife would go throughi'm a noob to this. can i just make it into pants or some shit like regular fabric or does it just not work that way?
>>65165947Yes to all of your questions OP.Don't forget to test it out while you're wearing it so that you know 100% that it works.
>>65165957Don't forget to ask your gf to film the test and upload it to youtube, you'll become famous if things goes really well.
>>65165957cool so how many layers do i use? i assume i can just calculate it from the tensile strength of the fibers or something then add two layers?do you people have experience in this or no
Okay jokes aside. There was at least one guy tried this in his garage several years ago and results extraordinary well, you may find his clip. I think he collected some used car airbags and a lot of glue, and glued them together the cut them in shape without a face mask..
>>65165962Historically, a rule of thumb is that 35 layers of kevlar = IIIA. Take this to /gq/ and you'll get armor autismos all up in your grill.
>>65165964yeah, i've seen a youtube video of a guy making composite plates. i wanted to build those, and have it go over a vest or some stuff like that see here, this guy builds this plate. i wanted to replicate this plate thing, then have the kevlar under it to have full body coverage instead of just in one area like the typical bullet"proof" vesthttps://www.youtube.com/watch?v=gFmIRM-zNqM
>>65165962I think anyone with a working brain wouldn't know the answer, because they would have bought them from a trusted manufacturer who would've gone through a lot more tests, industry standards, and credibility than anon in his garage with a tin snips.
>>65165947Just wear a denim jacket and hoodie according to k. No one with bad intentions will ever be using a 10mm and anything smaller will not penetrate your attire. Unless you're using it for home defense, then you're a moron and will over penetrate going through 2 dogs, 12 drywall sheets and 4 skulls.
>>65165993Well, if you vacuum epoxy enough aramid fabric layers together, they have to stop something eventually.
Be ready to waste a lot testing and figuring it out. I'd start making something like 10x10 squares and layering them, then put em over a sandbag and see how many it takes to stop a knife
>>65165947Desu I had the same idea about up armoring my leather duster ala Fallout New Vegas, I've got a pile of ballistic IIIA panels sourced from eBay a German Pfaff 360 from the late 60's and an inverter that makes it move fairly sluggish, but I'm hoping it's just gummy oil, but the inverter may be the problem and not supplying the correct power to it. basically my idea was to create a "smoking jacket" like the M65 jacket liner with the panels, overlapping to prevent slip throughs.Partly inspired by the north Hollywood shootout, and the damage threshold system of fallout
>>65166153>an inverter that makes it move fairly sluggish, but I'm hoping it's just gummy oil, but the inverter may be the problem and not supplying the correct power to itI don't understand, what do you have that's mechanized/electronic in your body armor
>>65166032I was curious enough to respond to your thread. Not curious enough to advise you against doing it. I say go for it , Anon! Post results!
>>65166158the heavy duty Pfaff 360 sewing machine I planned on using, uses a different power source wattage/voltage to operate on American electrical systems. i'm working on the pieces that sew the panels together. there isn't anything electrified i'm talking about the sewing machines used in the production of said potential body armor
>>65166181Ah, that was the piece of context I was missing. Thanks.
>>65165947For starters, there is soft and hard armor. A bunch of those sheets in a nylon packaging (for gods sake do not wear exposed carbon or glass fiber) does stop some calibers up to 9 mm and knives, but it's not super reliable.Hard armor is much better, but then you need to glue the layers together under vacuum with epoxy. There are many great Youtube tutorial which can show you the handicraft (vacuum bags, peel ply, general handling etc).What you REALLY want if you are stopping 9 mm and above, is cheap composite armor. Buy porcelain tiles (they have to be porcelain), use that as the face, it will shatter and abrade incoming bullets. The backing should be glass fiber composite, glass fiber is actually much better than carbon fiber here it absorbs more energy before cracking and is lighter. Finally either some thin metal or thick cloth behind to stop small fragments from slipping through and diffuse the impact over a larger area.There are open access research papers written on this stuff if you are interested in why you want these particular components.Personally I would buy prefabbed glass fiber composite plates and combine with a similar size porcelain tile, wrab everything in nylon and use a bunch inside of an other garment (design something like a brigandine I guess), where the armor elements overlap a bit.
>>65165947Spalling of fractured bullet.Design of product to use and intent of design.Chemical poisoning.>you're better off adding a metal plate under it
>>65165947Some people have even 3d printed armorWe really are in the age of material science
>>65165947>i'm a noob to this. Everyone has to start somewhere. Pioneering work is what drives human forward. I am pretty sure nothing bad will happen.>can i just make it into pants or some shit like regular fabric or does it just not work that way?Yeah, just make t-shirt out of it. Bulletproof t-shirt, how cool does this sound?
>>65165964>>65165947Thing to keep note about glue-based vests is that they WILL degrade after several years and need eventual replacement. Cheapness, leads to cheapness.
>>65166557Several years sounds good enough since this plate will be dirt cheap and not very difficult to make. Also I think military grade plates also have shelf life limitations?
>>65166557>>65166594Shelf life limitations are for extremely poor storage and manufacturer liability. There's plenty of epoxied armor panels that are over 30 years old and heavily used, yet are still stopping rounds at their rated specifications. The Italian AP98 level III PE plates come to mind, as do almost all aramid helmets. PASGT helmets from the 80s and 90s will still stop equivalent to IIA.
>>65165947If you use enough layers for it to be bulletproof, it won't be usable as a jacket, because it will be too thick and too stiff
YesMake a template out of paper firstSewing is fun af
>>65166032>epoxy enough aramid fabric layers together
