Also known as Opaque Armor or Kevlar, Bullet Resistant Fiberglass is a layered, reinforced structural polyester laminate (fiberglass) that offers unique bullet-resisting characteristics. Press molded between steel plates at high pressure and temperature, bullet resistant fiberglass progressively delaminates as a bullet penetrates, distorting and flattening the projectile and dissipating the energy. More energy is consumed as the bullet penetrates the high-strength glass fibers.
