Background

The bulletproof helmet is important equipment for head safety protection of individual soldiers or single police combat, the traditional bulletproof helmet is generally prepared by adopting an UHMWPE (ultra-high molecular weight polyethylene) jurisdiction composite material or an aramid fiber composite material in a lamination hot-press molding mode, and the integral bulletproof performance and the impact deformation resistance of the bulletproof helmet prepared by the single material are determined by the physical characteristics of the material. In the traditional materials, the UHMWPE fiber and the aramid fiber composite material have good bullet impact stopping characteristics, but the impact deformation resistance (back convex height) of the UHMWPE fiber is obviously different due to the difference of the physical characteristics of the fibers, the back convex height caused by the natural high-temperature creep characteristics of the UHMWPE fiber is larger, and the back convex height of the aramid fiber is lower, so that the impact protection safety of the inner wall of the helmet shell of the helmet under the same impact condition of the two bulletproof helmets made of different materials is obviously different.
The inventor finds that the aramid helmet has stronger impact resistance and lower back bulge resistance height of the inner wall of the helmet shell, but the aramid helmet has weaker ultraviolet aging resistance and seriously affects the protection stability of the service life of the helmet.

Example 5
In contrast to example 1, the outer surface of the hollow shield body was a three-dimensional woven material of T300 carbon fibers. The height of the back bulge of the lining part of the bulletproof helmet is 1mm. The three-dimensional woven material has better strength against deformation of the UHMWPE fibers than the two-dimensional woven material, but the three-dimensional woven material is costly.
Comparative example 1
In contrast to example 1, the hollow protective body employed a UHMWPE fiber composite layer alone.
The height of the back bulge of the lining part of the bulletproof helmet is 15mm.
The single UHMWPE fiber composite material layer has the anti-elastic capability, but the back convex height is larger, so that the helmet is larger in bulge and damage is caused to the head, therefore, in the embodiment of the application, the hollow protective body adopts the composite structure of the UHMWPE fiber composite material layer and the carbon fiber composite material layer, and the back convex height of UHMWPE fibers can be remarkably reduced.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
