Armor and ballistic materials are made of ceramics, high-strength fiber textiles, specialty alloys, and composite materials that are resistant to explosions, blast debris, shrapnel and high-velocity projectiles. They represent important materials systems in military, law enforcement, aerospace, and automotive applications. Products that incorporate armor and ballistic materials include body armor, personal protective gear, protective clothing, bulletproof vests, ballistic body armor, steel armor plates, vehicle armor, and ceramic tiles.
Ceramic armor and ballistic materials are usually made of alumina, zirconia-toughened alumina blends, boron carbide, or silicon carbide. They are used in body armor, personal protective armor, vehicle armor, rifle-resistant-armor, and structural composite armor. Ceramic plates are sold as individual tiles or complete tile kits. Length, width, thickness and area are dimensional specifications to consider. Common sizes include 4 x 4, 2 x 2, full, half, and custom. Density, median grain size and typical tolerance are also important specifications. Mechanical properties for ceramic armor and ballistic materials include flexural strength, compressive strength, Young’s modulus, fracture toughness, shear modulus, Poisson ratio, and hardness. To prevent tensile failure and cracking, a fiber backing may be used.
