Earlier quoted context omitted.

my back of the napkin math only puts this around the same stopping power as plywood of similar thickness. Sand bags work a lot better and are a hell of a lot easier and cheaper to produce

From my experience shooting plywood, the 9mm would have no problem going through the same thickness. He is legitimately on to something with his process.

A 9mm would get through 45 centimetres of plywood???

Another curious material if ballistic protection is your fancy, is fiber reinforced closed cell foamed concrete at a proper density and thickness. While not suitable as personal armor due to thickness (generally around 1.5ft/45cm), it’s something can provide rapid and cheap local access to protection from shrapnel and rifle bullets, which unfortunately is still a genuine concern around the world. At lower density foa…

Plywood rots unless protected. But if you're going for engineered solutions then plywood layers spaced apart with something a bit more flexible/compressible would be more effective and possibly lighter than a solid block of wood.

That's some amazing amount of effort! I was hoping to see him contact the authors of the paper to get their comments on his methods, and in particular on the seemingly incomplete chemical treatment shown in the cut block.

He could try starting with e.g. 3x thinner blocks to ensure chemical treatment reaches the core, and then glue 3 of those together to end up with the same thickness as his single layer. Curious to see the bullet performance of that.

What are you on about. 45cm is INCREDIBLY thick, and a solid plywood block of that thickness will probably stop high caliber rifle bullets.

I've used telephone books as backstops in the past and abour 3-4 of them is enough to stop a handgun bullet easily.

We use 10mm mild steel plates for targets, and they don't even dent when shot with a 9mm round.

45cm of almost anything with similar density will provide suitable protection. Sand bags, bricks, wood, glass, paper etc.

"Computer Shopper" magazines made for great backstops when zeroing scopes in a .22lr rifle.

I suspect layering paper with a squishy resin in multiple layers would be very effective armor. Is paper close enough to call it "from wood"?
