Problems solved by technology

[0002] Bulletproof helmet is an important equipment for personal combat head safety protection. At present, traditional bulletproof helmets are made of UHMWPE fiber composite material or aramid fiber composite material by hot pressing. There are many problems in the characteristics, for example, the high temperature creep problem of UHMWPE fiber composite material is serious, and the overall deformation in the protection process of projectile invasion and retreat is relatively large; the anti-ultraviolet aging problem of aramid fiber composite material is serious, which affects the service life and safety of the overall helmet
In order to improve these problems, researchers tried to use carbon fiber and the above fibers to form a laminated bulletproof helmet to solve the problem of rigidity and aging resistance during bulletproof and service, and achieved good results. However, the protection level of these helmets has always been It cannot be effectively improved, and only stays at the defense level of pistol bullets
In the face of submachine guns, automatic rifles or semi-automatic rifles, there is no effective protection performance.
[0003] Bullet-proof ceramic materials have excellent mechanical properties such as high hardness and low density, and have been widely used in heavy-duty bullet-proof armor. Research on individual soldier protective equipment of composite configuration is prepared by using bullet-proof ceramics and traditional composite materials to form a combined structure Less, mainly because the overall density of bulletproof ceramics is higher than that of fiber composite materials, and the overall weight affects the portability and comfort of carrying and wearing

preparation example Construction

[0036] On the other hand, the present invention also provides a kind of preparation method of above-mentioned honeycomb barrier structure ballistic helmet, comprises the following steps:

[0037] Firstly, the two-dimensional fabric of high-strength fiber is impregnated with composite thermoplastic resin, which is laminated by cutting technology, and the inner buffer layer helmet shell is formed by molding process; the high-strength carbon fiber two-dimensional fabric is impregnated with composite thermosetting resin matrix to form a pre- Immerse the raw material, also use the cutting technology to stack the layers and prepare the middle rigid layer on the outer layer of the inner buffer layer helmet shell by compression molding. The maximum pressing pressure used is 25MPa, and the hot pressing temperature of the buffer layer is in the range of 120-140°C. The hot pressing temperature of the rigid layer is controlled within the range of 120-160°C.

[0038]Further, both the middl...

Abstract

The invention discloses a bullet-proof helmet with a honeycomb block structure and a preparation method of the bullet-proof helmet, and belongs to the technical field of bullet-proof helmets. The bullet-proof helmet comprises a honeycomb block layer, a middle rigid layer and an inner buffer layer from outer surface to inner surface sequentially, wherein the honeycomb block layer is formed by filling a hexagon columnar ceramic micro-cylinder with a chopped carbon fiber composite material; the middle rigid layer is formed by impregnating carbon fiber 2D woven fabric with a thermosetting resin matrix; the inner buffer layer is formed by a thermoplastic resin matrix reinforced by a preform fabric structure with a high-toughness fiber 2D woven structure; a carbon fiber thermosetting composite material layer is further arranged on the outer layer of the honeycomb block layer. The bullet-proof helmet is high in toughness, small in overall deformation under bullet impact, lighter in weight andconvenient to carry and wear, and comfort is improved.
