The success or failure of modern warfare is still to solve the problem of spear and shield. Guns, artillery, and missiles are spears, and bulletproof armor is a shield. In anti-violence and anti-terrorist struggles and modern large-scale wars, bulletproof armor can reduce casualties, increase combat effectiveness, and increase victory factors. Therefore, research and development are Very necessary.
The general development trend of armor materials is toughness, light weight, multi-function and high efficiency. Ceramic material is an important part of ballistic materials. It has high hardness and wear resistance, high compressive strength and excellent ballistic performance under high stress. The M value in the formula is the ballistic quality factor, which characterizes the anti-elasticity of ceramic materials. can.
E, modulus of elasticity
H, hardness
ρ, density
