ABSTRACT
A bulletproof vest is an item of personal armor that helps absorb the impact and reduce or avoid penetration to the body from firearm-fired projectiles and shrapnel from explosions. Bulletproof materials work by absorbing the kinetic energy of the fired shot and dissipating it so that the speed of the bullet reduces to nearly zero, which decreases the penetrating power and damage that is done. When a bullet hits a Kevlar vest, it gets caught in the web of strong fibers, which absorbs and dissipates the energy, drastically reducing the impact of the bullet. This happens because the fibers are lined up so tightly that it takes a great deal of energy to separate them. Sometimes, the vest is strong enough to cause the bullets that hit it to become distorted or bent. Even though the Kevlar could stop the projectile from penetration, the depression depth in the backing material could result in Backface Signature injury. This project aims to create a new composite which could reduce the Backface Signature (BFS) both effectively and economically.
