Why can alumina ceramics be used as bulletproof materials?

Recently, many friends have come to inquire about bulletproof ceramic sheets. Many people may have questions, why alumina ceramics Can it be used as bulletproof material?

Alumina ceramics have high hardness, High strength, wear resistance, corrosion resistance and other good properties. When resisting the impact of warheads, metal materials willProduces plastic deformation and absorbs energy, while ceramics hardly It produces plastic deformation and relies on its high strength and hardness to passivate or even break the warhead. The ceramic surface is crushed and absorbs the energy of the high-speed warhead in the process of forming small and hard fragments. In addition, alumina ceramics are heavier than metals. Light, can greatly reduce the equipment load

Therefore, the application of alumina ceramics in the military field is also very attractive, and it has been widely used in body armor Protective armor for vehicles, aircraft and other equipment.
