Common impression of ceramic is fragile, but in the join boron carbide this high strength of new materials, and after modern technology processing, because of Boron carbide bullet resistant material has high hardness, low density, high elastic modulus, corrosion resistance and other ceramic materials do not have a good neutron absorption ability, in bulletproof armor, nuclear power and wear resistance technology is widely used.
The basic principle of armor protection is to consume the energy of the projectile and make the projectile slow down to reach a harmless degree of energy, while the Boron carbide bulletproof ceramics absorbs the energy through the process of micro-crushing. From the initial impact of the ceramic material, the impact weakens the warhead and absorbs energy during the crushing of the boron carbide ceramic surface to form a fine and hard fragment area.The next blunt projectile continues to erode the debris area, forming a continuous layer of ceramic fragments; then during the deformation, fracture and fracture stages, the tension breaks the ceramic, after which the remaining energy is absorbed by the deformation process of the backplane material.
The requirement of material properties in the field of bulletproof makes boron carbide ceramics become one of the more popular ceramic materials in the industry. Boron carbide is a superhard material with hardness second only to diamond and cubic boron nitride in known materials. It is one of the three materials with the highest hardness. With the development of modern sintering technology, the excellence of boron carbide ceramics is becoming more and more prominent, and Boron carbide bulletproof plate application in the field of bulletproof has been further developed.
