Alumina ceramic لوحة مضادة للرصاص is inserted in high-strength and high-modulus fiber composite plate. Its high specific stiffness, high specific strength and chemical inertness in many environments make it almost impossible to produce plastic deformation. When the high-speed projectile and When the ceramic layer collides, the ceramic layer breaks or cracks and spreads around the impact point to consume most of the energy of the projectile, and then the high-modulus fiber composite plate further consumes the remaining energy of the projectile, and the projectile will be damaged due to its own high strength. Passivated or even broken due to its hardness and hardness characteristics, so as to achieve the purpose of bulletproof.
