if you use harder/tougher strike face, maybe thicker glass to slow down and mushroom the initial high velocity of the 44mag first, then some cushioning layer to absorb shard movement a little bit so they don't shatter thinner pieces of glass in the glass-PC sandwich and then last layer of PC make it either thicker or use even thinner layers sandwiched with another transparent plastic with good ductility, maybe PET with sticky non-crystalizing adhesive to prevent delamination
Some pieces looks like it's acrylic. As you said ductility is different. And AFAIK acrylic makes "stars" in impact zone. But now I'm in doubt. From other videos of testing transparent armor without glass, it looked like it consisted of polycabonate-acrylic-polycarbonate. Because inner layer made "stars". Or maybe it wa different sorts of polycarbonate
Have you tried glueing 2 polycarbonate sheets with urethane or with clear epoxy resin? Instead of screwing (or bolting) them. It should be clear and not impair clarity I think from other videos where they do that. Also I read 1,25" inches of PC should cover handguns including 44 magnum according to tssbulletproof site. Apparently Poly-Acrylic-Poly performs the same as all Poly, in 1,25" thickness. What I wonder is about the thickness of each layer, how it matters and also the urethane vs clear epoxy resin. Amazing 2 shots in the same spot by the way. Cheers
@@segundacuenta726 I have glued the polycarbonate together and urethane works better than epoxy. Right now, I prefer using a mixture of TPO (POE) mixed with a bit of mineral spirits. It also works with Poly-Acrylic-Poly
It would nicer to see different samples not compromised maybe. Even so, very interesting results, very good resistance, ¿is there some best option for maybe making it lighter and thinnest so can be use for a car window and allow it to toll?
Hey curious about the outside the car glass stuff they advertise getting whacked with a bay, speculating a wind screen with both inside and outside covered, it could be better protection? Does it work that way?
That’s a wide variety of materials. Many banks only protect against pistol threats, where as armored trucks protect against full range of rifle threats. So many banks actually use a polycarbonate and acrylic product for clarity and impact resistance against other less threatening types of objects (bats, fists, office furniture). Most armored trucks use a glass clad polycarbonate
Good work as always!
I think the 3/8 and 3/8 could have stopped 762x39 FMJ
Ballistic testing, the only time when marksmanship is a double edged sword.

Great information, thanks for sharing bro!

Ithats actually the UV resin binder between the layers that create the “star” pattern. There was no acrylic used in this project.

2 in the same hole! Love watching ur videos
That is some slow 357. Wow

What are things like some banks and armored trucks using for glass?

I’ve spent my adult life trying to get a follow up shot to go through the same hole. This guy does it with a pistol. Ridiculous.
lol that was insane.
