Alumina ceramic is a kind of high hardness, high wear resistant material, according to the different Al2O3 content, it can be divided into 99% alumina ceramic, 95% alumina ceramic, 96% alumina ceramic, 92% alumina ceramic and so on. The main characteristics are high temperature resistance, corrosion resistance, wear resistance and impact resistance, which are industrial grade special ceramics.
The general development trend of armor materials is toughening, lightweight, multifunction and high efficiency. Ceramic material is an important part of bulletproof materials, which has high hardness and wear resistance, high compressive strength and excellent ballistic performance under high stress.
99% alumina ceramics can be used as bulletproof ceramics. Because of its high hardness and strength, when a bullet impact ceramic surface, it creates a powerful force of impact, the impact force extends to the ceramics and the bullet, and under the impact force, the ceramics break up slightly, resisting the penetration force of the bullet. Alumina bulletproof ceramics absorb the kinetic energy of bullet by micro-breaking, so as to achieve the function of bulletproof. Bulletproof ceramics are three to four times stronger than steel armor, providing much higher protection than steel armor.
Of course, due to the brittleness of ceramics, only relying on the ceramics themselves, can not be done “foolproof”. Bulletproof ceramics are generally placed on the surface of the bomb, to be bonded together with other backing materials, composite armor common use. The main function of the backing material is to absorb the residual ballistic impact energy.
In order to improve the resistance of ceramics to multiple strikes, the ceramic panels are often coated with high-strength fiber fabrics to prevent crack propagation caused by bullet strikes. The combination of high strength hard ceramic and rigid backing constitutes the basic structure of modern ceramic composite armor.
Modern warfare is still won or lost by solving the problem of spear and shield. Guns, guns and missiles are spears, while bulletproof armor is a shield. In the struggle against violence and terrorism and in modern large-scale wars, bulletproof armor can reduce casualties, improve combat effectiveness and increase the factors of victory.
