Problems solved by technology

However, helmets made of fiber-reinforced composite materials are mainly formed by prepregs impregnated with fibers and resins, which are formed by cutting, laying up and hot-pressing processes. During the pressing process, there will be an inevitable situation of unbalanced pressure with the top of the helmet, and this is also an inevitable problem in the helmet molding process, which will bring about the instability of the back convex height and side wall during the projectile penetration process
[0004] It can be seen that the composite bulletproof helmet prepared by the prior art still has the problem of unstable back convex height and side wall performance. Therefore, it is necessary to study a new composite bulletproof helmet

Abstract

The invention relates to a partially reinforced composite material bulletproof helmet, and belongs to the technical field of composite material bulletproof helmets. The helmet comprises an outer bulletproof layer, an intermediate buffer layer and an internal rigid reinforcement layer successively from outside to inside, and the interface layers of the outer bulletproof layer, the intermediate buffer layer and the internal rigid reinforcement layer are bonded into shape. The outer bulletproof layer is mainly composed of laminating and hot pressing pre-impregnated fabric which is formed by fiberimpregnated resin, the intermediate buffer layer is composed by compositing a fiber or foam structure material with a honeycomb hollow structure and a resin material, and the internal rigid reinforcement layer is composed of a composite material of high-modulus carbon fiber reinforced thermosetting resin, wherein the thicknesses of the internal rigid reinforcement layer of the forehead position and the hindbrain position is larger than that of other parts. According to the partially reinforced composite bulletproof helmet, by using the characteristics of the composite material, through partial arrangement of the reinforcement layer in the bulletproof helmet, the back-convex deformation height of key positions is ensured, and the problem of unstable side wall of the back-convex height in the projectile penetration process is greatly solved.

Description

technical field [0001] The invention relates to the technical field of bulletproof helmets made of composite materials, in particular to a bulletproof helmet made of composite materials which is partially reinforced and can improve the back convex deformation of the local impact of projectiles on the helmet. Background technique [0002] With the emergence and development of high-performance fibers, various high-performance special fibers have become the main reinforcement materials for composite material helmets due to their high strength and toughness, and this kind of composite material helmets have gradually replaced steel helmets. Quantify the main product of helmets, fiber-reinforced composite bulletproof helmets are mainly made of high-performance fiber-reinforced special resins such as UHMWPE fibers, aramid fibers, and PBO fibers, which have good ballistic performance. [0003] At present, although the traditional single-material composite bulletproof helmet has many...
