Embodiment Construction

[0012] see figure 1 and figure 2 , The helmet of the present invention is composed of a ceramic matrix layer 1 in the middle, a PE layer 2 attached to the inner side of the ceramic matrix layer 1, and a PE layer 3 attached to the outer side of the ceramic matrix layer 1 and formed by thermocompression bonding.

[0013] The ceramic matrix layer 1 is composed of a plurality of polygonal prisms, pyramids and truncated polygons 4 , and the facets between adjacent ones of them are closely attached to each other without gaps. The number of edges of the polygonal prism, polygonal pyramid and polygonal truss 4 is 3-7. The different curvatures of different regions of the helmet are formed by splicing polygonal pyramids with different tapers and polygonal trusses and polygonal prisms. The material of the ceramic matrix layer 1 includes aluminum oxide, boron carbide, silicon carbide or silicon nitride.

[0014] Through testing, the present invention can effectively resist automatic r...

Abstract

The invention discloses a ceramic light-quality bulletproof helmet and preparing method, which is composed of ceramic base layer in the middle of helmet and PE layer on two sides through hot-pressed attaching, wherein the ceramic base layer is split by multiple prismoids, multiple pyramids and multiple bosses. The preparing method comprises the following steps: designing PE layer on the inner side of outer and inner surface of inner mould; splitting a layer of ceramic multiple prismoids, multiple pyramids and multiple bosses on the inner side of PE layer; pressing inner and outer mould through heating.

Description

technical field [0001] The invention relates to a safety protection device for a human head and a manufacturing method thereof, in particular to a bulletproof helmet. Background technique [0002] Most of the existing bulletproof helmets are stamped from metal bulletproof plates, which are heavy and easy to detect targets with infrared rays. Usually, they can only protect Type 54 pistol bullets, and the protection level is low. At present, there are a small amount of bulletproof helmets made of polymer materials. The weight has been reduced, but the protection level is very low. Faced with the continuous upgrading of light weapons, semi-automatic rifles, automatic rifles, and sniper rifles are more powerful. The original bulletproof helmets have been difficult to meet bulletproof requirements. Better bulletproof helmets must be produced to meet the needs of future wars and anti-terrorist struggles. Contents of the invention [0003] The object of the present invention is ...
