Example Embodiment

[0023] The present invention will be further described below through specific embodiments.

[0024] See Figure 1 to Figure 5 , The body armor with a composite structure provided by the present invention mainly includes a bullet-absorbing layer 200, a protective layer, a buffer layer 300, and an energy-absorbing layer 400 from the outside and the inside, and the layers are glued together.

[0025] The bullet-absorbing layer 200 includes two carbon fiber layers 201 and an aluminum foam layer 202, and the aluminum foam layer 202 is sandwiched between the two carbon fiber layers 201. Compared with traditional metal materials, carbon fiber has the characteristics of high strength, high modulus, low density, and low linear expansion coefficient. As a filling material, aluminum foam has low density and high impact absorption capacity. The purpose of this layer structure is to make the bullets collide with the body armor, the body armor can absorb the bullets to avoid stray bullets.

Abstract

Composite body armor comprises a bullet absorbing layer, a protection layer, a buffering layer and an energy absorbing layer from exterior to interior. The bullet absorbing layer is used for absorbingbullets so as to avoid stray bullet generation, two carbon fiber layers and an aluminum foam layer are included, and the aluminum foam layer is sandwiched between the two carbon fiber layers. The buffering layer is used for converting point impacts into face impacts. The absorbing layer is used for absorbing deformation of the buffering layer. The composite body armor can effectively avoid straybullet generation and fighting personnel rib fracture danger caused by excessive impact force.

Description

technical field [0001] The invention relates to the technical field of safety protection equipment, in particular to a composite body armor. Background technique [0002] With the development of modern technology, more and more attention has been paid to military protective equipment. Body armor is a single protective equipment used to prevent bullets and shrapnel from causing harm to people. This plays a very important role in guaranteeing the safety of soldiers, so higher performance requirements are put forward for the protective performance of body armor. [0003] Existing body armor mainly uses ceramic materials such as steel plates, hard alloys or alumina as protective plates to prevent warhead shrapnel and the like from causing harm to people. However, because the outermost layer of the traditional body armor is made of steel plates, when the bullet hits the body armor, there is a high probability that the bullet will eject and form a stray bullet, which may cause th...
