When I iron this, the goal was to just iron long enough to bond the layers, not melt the fibers. If you keep the iron on too long you stand to wreck the fibers and, with them, their ability to stop bullets.

Dude, genius move with the iron! They don't even teach prototyping skills like this in college!

UHMWPE is just amazing. I have a full set of the SG Italian stuff. I tested it and it held up to a lot more than I'd ever expected.

Material looks good for making full body armor like in historical wars.

New job for my heat press. Thx!

I work in a plastics extrusion factory.....i know what im doing next time we run 1.2mm hmwpe sheets lol

If you REALLY want to construct UHMWPE laminated sheet armor that works against all handgun rounds, create enough layers to stop a 5.7x28 FN SS197SR, and the SS198LF. If you don't have access to one of those, test it against .22 TCM and or .22 TCM9R. When you get to a number of layers that stops those rounds - you're there. The resultant laminate will stop any and all 9mm, .38, .357, .40, .45, 10, and even .41, and .44 magnum. given that it's "soft" armor the super heavy calibers can still damage or kill by energy transfer into the target, but the bullet will not penetrate.

nice.I wonder if you can make a tile by just rolling and ironing a long tape of PE instead of doing that on squares of PE sheets cut out.

Should incorporate some kavlar or carbon fiber in the layers into this.

For how stiff it is for 24 layers and duct taped would this still have enough flex for use as a standalone pistol rated vest face ?

Hi, would you mind sharing this discord group? Also, what if you put 1/8 piece of steel behind this uhmwpe in the chest and rib area to stop the blunt trauma? Will be significantly heavier but better than cracked ribs

what is the point of that? the bullet stopping ability is the same or maybe worse
