Problems solved by technology

[0004] However, the overall defensive properties of advanced bulletproof fiber composites have bottlenecks after all. There are still problems in preventing the penetration of projectiles fired by large single-person weapons such as sniper rifles, heavy semi-automatic rifles, and heavy submachine guns. To meet the requirements, it is necessary to make products with large thickness and heavy weight, which often makes the original characteristics of lightweight composite materials lost, and loses the meaning of mobility and flexibility.

Abstract

The invention discloses a ceramic composite material bullet-proof chest board and a preparation method thereof. The ceramic composite material bullet-proof chest board is composed of a carbon fiber composite surface rigid layer, a ceramic composite material sheet combination layer, a bullet-proof fiber composite material body layer and a back elastic surface carbon fiber composite back-convex-proof layer. The ceramic composite material sheet combination layer is made of special fiber reinforced ceramic matrix materials and is of a needling insertion type combined structure or a three-dimensional crazing-prevention framework structure; a composite cementing and micropore riveting combined technology is adopted between the ceramic composite material layer and the bullet-proof body layer; finally, the ceramic composite material sheet combination layer and the bullet-proof fiber composite material body layer are wrapped in a rigid structure composed of the carbon fiber composite surface rigid layer and the back-convex-proof layer to form a whole. The ceramic composite material bullet-proof chest board has various advantages of being light, low in back convex, stable in high and low temperature structure, long in service life and the like. Meanwhile, the problem that a seam bullet-proof characteristic in a traditional splicing structure of ceramic sheets is poor is effectively avoided, and the ceramic composite material bullet-proof chest board has the overall characteristics of multiple bullet-proof materials.

Description

technical field [0001] The invention relates to a ceramic composite bulletproof chest plate and a manufacturing method thereof, in particular to a method for preparing a bulletproof chest plate combined with ultra-high molecular weight polyethylene fibers, carbon fiber reinforced composite materials and ceramic sheets. Background technique [0002] Although the world tends to develop peacefully and large-scale wars and conflicts are less likely to occur, incidents such as international terrorist activities and internal riots continue to occur. Such incidents, which are characterized by small-scale and individual crimes, are naturally Peacekeepers, especially individual police or individual soldiers, put forward special requirements for protective equipment. For rioters or terrorists, they still hold long-distance and high-injury weapons such as sniper rifles, heavy submachine guns, and heavy semi-automatic rifles. For the personal safety of soldiers and policemen, it is nece...
