A two-stage combined ballistic ceramic unit

Abstract

The invention discloses a two-section combined bulletproof ceramic unit. The two-section combined bulletproof ceramic unit is characterized in that the unit is composed of two parts, an upper half structure is composed of aluminium oxide ceramic materials, a lower half structure is composed of boron carbide materials, and a binding agent is arranged between the two structures. The total height of the combined bulletproof ceramic unit is 15-30 mm. The radius of a cylinder part of an upper half aluminium oxide ceramic and the radius of a cylinder part of a lower half boron carbide ceramic are equal and are 12-28 mm. A protruded arc face is arranged on the top of the aluminium oxide ceramic, and the radius of a curved surface is 1 / 2-2 / 3 of the total height of the ceramic unit. The height of the boron carbide ceramic is 40%-65% of the total height of the ceramic height. The butt joint mode of the upper half structure and the lower half structure is embedding of one to two columns, and the height of the columns is 2-5 mm. The two-section combined bulletproof ceramic unit integrates with the advantages of effectively resisting high-speed bullets of the aluminium oxide ceramic and being low in density of the boron carbide ceramic. According to the two-section combined bulletproof ceramic unit, the two sections of ceramics of the aluminium oxide materials and the boron carbide materials are combined to the bulletproof ceramic unit, and penetration of armor-piercing incendiaries with middle and small calibers, particularly armor-piercing incendiaries of 7.62 mm, 12.7 mm, 14.5 mm and the like, can be effectively resisted.

Description

Technical field [0001] The patent of the present invention relates to a ballistic resistant ceramic unit, in particular to a two-stage combined ballistic resistant ceramic unit, which is mainly used to resist the penetration of high-speed armor-piercing incendiary bombs, and can be applied to armored vehicles, armed helicopters and upper layers of ships The armor protection of buildings and other fields. Background technique [0002] The general development trend of armor materials is toughness, light weight, multi-function and high efficiency. Ceramic material is an important part of bulletproof materials. It has high hardness and wear resistance, high compressive strength and excellent ballistic performance under high stress. Compared with metal armor, ceramic armor has better resistance to elasticity, especially for high-speed bullets. The most commonly used ceramic bulletproof material is bulletproof alumina, but the weight of bulletproof alumina can no longer meet the fast...

AI Technical Summary

Problems solved by technology

This traditional ceramic column structure is not only dense, but also the ballistic resistance of alumina is significantly lower than that of other ceramic materials such as boron carbide and silicon carbide.
