when a hand gun bullet strikes body armor, it is caught in a "web" of extremely strong fibers. these fibers absorb and disperse the impact energy that is transmitted to the bullet proof vest from the bullet causing the bullet to deform, otherwise known as a "mushroom". additional energy is absorbed by each successive layer or material in bullet proof vests until such time as the bullet has been stopped.
