Current composite armor systems are fragile.

Which is why armor is rated around preventing pe. armor, titanium, body, weapons, penetration, superplastic, Ti6Al4V, 7.62x39mm. That will kill you just as readily as a bullet. You just need to inflict enough blunt force trauma that the impact will break bones and send the fragments into your vital organs. In Rabiei’s vest, the boron carbide stops the bullet, but it’s the CMF foam behind it that absorbs the kinetic energy - so much of it, in fact, that the bullet appears to vaporize on impact. Answer (1 of 4): You don’t need to penetrate Level IV armor to kill. The boron carbide ceramic strike face is commonly used in other body armor, but the plate’s core is lightweight CMF foam. Rabiei and her team fashioned an armored plate made out of a composite of materials. Afsaneh Rabiei said that CMFs had a lot of potential uses in personal and vehicle armor, but their potential uses go a lot further than that. In a study published last year, NC State’s Dr. It’s called Composite Metal Foam, or CMF - a metal structure filled with porous gas bubbles that decrease its density and weight drastically, but keep much of the original metal’s strength. But researchers at North Carolina State University’s Department of Mechanical and Aerospace Engineering think they might have found a better option than solid steel. Conventional body armor uses heavy steel or ceramic plates inside a kevlar vest to stop the massive kinetic energy of an armor-piercing bullet. Supercheap Auto is New Zealands leading auto spares, parts and accessories retailer stocking a variety of car batteries, air filters, coolants and more. Usually, it takes a lot of heavy, cumbersome metal to stop a bullet.
