it clearly says it's a structured polymer composite... meaning it's comprised of more than one material, and also with structured layers with different properties (layers being 20nm thick). doesn't say anything about polycarbonate, although I wouldn't be the least bit surprised if it was a component. the other article they linked to has more info:

"The researchers were inspired by their observations in macroscopic ballistic tests in which a complex multiblock copolymer polyurethane material showed the ability to not only stop a 9 mm bullet but also seal the entryway behind it."

Microbullets reveal material strengths

Yes, sorry I meant polyurethane not polycarbonate.

It is still not a new material it is a new method of laying a possibly new blend of materials to mimic the polyurethane but better.

its similar to the combination of armors with spider silk weave - keep in mind that preventing penetration is one part of it

so if you have a layer that prevents penetration
another layer that absorbs kinetic energy and disperses it
then you layer both for redundancy for things that OVERPENETRATE
you get a system of prevention

you combine different kinds of strength - the end result is going to have more bulk and girth yes - but given the choice of no protection vs reasonable protection well... =P

are the clear shields swat guys use bulletproof? i wonder if its heavy

[ApoC_101]

I think you may be confusing riot shields and ballistic shields... SWAT guys use the bulletproof ones which have a small window in them (the rest is metal AFAIK).

What about covering body panels of cars/trucks with this stuff? It would give it some more bullet stopping capabilities without much weight. I know the army wanted to build a tank you could drop from an airplane, this could help.

Parachute might be a good investment too

You don't know the right info then...

Kevlar® Glove with PVC Dots

And those are the cheap ones. They make all sorts of gloves that are stab and slash resistant also... that are made out of Kevlar. They've made those for a long time now.

Slash resistant is one thing, passing an ice pick test is another.

That'd be too easy right?

No because some people need to be shot. This stuff is to protect those we don't want to get shot.
