Since the invention of bulletproof ceramic armor by Joe Bam, reaction bonded silicon carbide ceramics with high hardness, small specific gravity, large area of protection, small distance between two impact points, good ballistic performance, and can absorb more energy after fragmentation, it is widely used in military protection, such as the protection of various armored vehicles, armored vehicles, ships, as well as the protection of civilian safes and armored cars. The bulletproof ceramic plate has better ballistic performance than alumina ceramics, which is approximately 70-80% of boron carbide ceramics. However, due to its low price, it is particularly suitable for applications where the amount is large and the protective armor is not too thick or heavy. It can effectively prevent the penetration of the warheads of firearms of the third-level or above. At the same time, it can avoid or significantly reduce the non-penetrating damage caused to the human body when it is struck. Bulletproof ceramic armor plate can be used as a protective armor for weapons and equipment such as vehicles or airplanes, especially for armored missiles. And it can be customized according to different protection levels, different thickness, shape (square or hexagon) size, etc.
