Testing common Materials that can stop bullets

[@kungfugirevik657]

It's good to see you combining materials for their different properties, and testing against spicier rounds is a nice touch. You and I seem to be along the same research paths. I've been binge watching armor demo videos (Buffman's are by far the best), as well as reading journal articles and material science websites. I've been looking for failure points and methods, optimal stacking sequences, etc. One thing I've learned is that the armor industry is rather stagnant with their designs compared to the available literature on the topic.

something worth trying could be allu + fiberglass as a backer, as fiberglass is stiff, and so will give structural support vs plugging method (in a similar fashion as one of the samples i build and tested with techthisoutmeow last year, where 15mm of 7075 T6 + 6mm of 6061T6 backer, where the backer kept the 7075 t6's plug in place and prevented penetration)

So cool you're doing this stuff for everyone, my favorate vids are the 3O8 proof glass and buIIet proof concrete. Im thinking of making a big rolling balistic shield using welded together 1/2in ar500 rectangle gongs (from sh⭕️⭕️tsteel▫️c⭕️m) with 2 or 3 layers of 3"X3" inch segmented capri classic tiles stuck on front to contain spall and increase protection from lvl3 to lvl4, the 3O8 glass you made would be on top at eye level. Cheaper but more experimental methods would be replacing the ar500 gongs with your concrete as a huge slab (that might be too heavy though), or possibly using Tech this out meow's milk jug uhmwpe rifle armor method instead of the gongs (thats a lot of work, milk, fiberglass, and resin though so probably not worth it).

I just beat youtube 1st Amendment censorship with ⭕️ as o's, ▫️as .'s , i's as L's They dont want you to say "buIIet proof" or "3O8", like wtf who does that offend.

A+

Suggestion: A hard rubber coating on the strike surface might help- not in making the armor more impenetrable, but rather decent(ish) at slowing the round. As cheap as possible. I saw another video of using a welding blanket and 2 part epoxy. Tried to copy it as best as possible and used some cheapo amazon hard "ruber" coating, maybe a 1/4 inch(?) Seemed to work well enough. Certainly kept the backboard from delaminating from 9mm. Did not test anything else cause i dont havr anything else 😅

[@3RBallistics]

@@WarkWarbly I definitely look into that. Thanks

Hi would it be possible to get timestamps where you start testing a new material? Your videos are full of information but its hard to figure out what I'm looking at without searching the exact moment you mention what it is you are shooting at.

[@3RBallistics]

@@caseyb1346 I will definitely look into that

[@randygoolsby4893]

Just wondering - has anyone ever tested ceramic stove top material as a strike face? I'm referring to the material that looks like dark tinted glass but is (I think) some kind of high-strength ceramic.

[@Meop79]

It would have been more interesting to have fiberglass plates like the fiberglass plate in front of the other plates seeing which of the other plates made the best backer

[@3RBallistics]

@@Meop79 I do have that test if you’d like to look at some of the past videos.

[@Meop79]

@@3RBallistics will do, my experience in that fglass does a good job disrupting and slowing them. I am currently testing a fairly thin reasonably light multi hit capable 300wm stopper. Zero backface deform. The 1 st layer is 6 layers welding blanket and hdpe heated and compressed.

I really want a 460 someday 😂

audio was very low on this video
