Personal protection challenge. No metal, no tile. What can we build with $25 and one WallyMart store. Trying to stop light rifle rounds. For entertainment only!
1. wood pulp and PVA glue. how thick it needs to be to stop a bullet. 2. sand/stone dust held together by urethane epoxy 3. glass beads plus epoxy 4. combination of above
@@3RBallistics I think your creative use of additives, fillers, and binders of various sorts could really help. The way you use textiles is impressive.
Level 4 helmet out of porcelain and steel or level 4 helmet out of old helmet, hard hat or current helmet if thats too hard for you. That or one quarter inch thick high carbon tempered steel helmet and try to get it to be ar 600 steel. Thickest ar 600 like helmet I have seen so far is 2mm and stopped like 5 rounds of 357 in the same place.
Here is a interesting chalange for you (I'm going to copy paste this comment on afew videos so you notice it)... Fiberglass balistic helmet or just a full diy balistic helmet series including back face deformation testing. My idea is a fiberglass helmet with thin steel bars impeded on the inner layers of fiberglass forming a lattice shape to prevent serious back face deformation.

Great info, the shield was a surprise! Thanks for sharing!

You could look into Aircrete (foamed concrete) for weight savings.
I’ve made aircrete for a planter once. I’ll have to look into that a little closer to see if I can make it thin and strong as well as light.

Should collab with Tech this out Meow even if its just for ideas he is another channel experimenting in this science.
We collaborate quite a bit. More behind the scenes and on his discord. He’s a great guy with tons of material knowledge and I’m lucky to know him.
