The application of boron carbide in the field of bulletproof armor
Because B4C ceramics has the characteristics of light, high hard and high -elastic modulus, it is the best material for bulletproof vests, bulletproof helmets and bulletproof armor. In the 1960s, carbonized boron ceramics began as ceramic armored materials. Compared with other bulletproof materials (such as SIC and Al2O3), B4C ceramics are lighter and harder. It is especially suitable for armed helicopters and other aircraft as bullet -proof armor materials to effectively resist the shells. Therefore, B4C ceramics are generally only used for special occasions that have high requirements for protective performance, such as the U.S. V22 “Merlog” rotating wing aircraft. In addition, the enhanced human armor (EBA) used by the British army also uses boronized boronicidal ceramics, which can defend the 12.7mm steel heart -piercing bomb.
