Abstract
Protection offered by plastic shields to chemical explosions was investigated. Target plates of nine different plastics were subject to the impact of .22-caliber, high speed, short bullets. Polycarbonate plates or varying thickness were also tested. Goggles, face shields, and body shields made of these materials were evaluated in light of these findings. Twenty one vinyl plates, 22 of acrylic plates, 12 of fiberglass plates, and 13 styrene plates were penetrated before the bullet was stopped by the following sheet. Bullets penetrated only four polycarbonate sheets before being stopped by the fifth. A significant increase in protection was found when plate thickness was increased above 0.093 inches. A face shield of two layers of 0.125 inch polycarbonate had a higher impact than one with a single 0.250 inch plate. The authors conclude that polycarbonate sheet affords the best protection from explosive impact at this time. Its use in goggles, face shields, and body shields is recommended.
