its only the strongest metal. why dont we make diamonds out of kevlar to make them bulletproof?

on a serious note, diamond would actually make a decent materical for trauma plates
>hard but brittle
thats the point of trauma plates. you use the hard material with a tougher backing and some layers of kevlar
would it be better than boron carbide? maybe not. extreme hardness isnt that important as long as its much harder than the bullet and boron carbide is a little bit lighter and might have better crack propagation properties (for multi hit protection). cubic boron nitride is easy to make and is harder and more similar to diamond, but its not used very much for armor
i could also see diamond-like-carbon being useful, maybe layered with some ceramic or metal because its easy to make thin layers of it and delamination like effects soak up energy

If diamond is the strongest material why dont they make kevlar vests out of it?
