Problems solved by technology

[0004] The main purpose of the present invention is to overcome the problems that the structure of the body armor in the prior art is too simple, the resistance to deformation is poor, the impact force after the collision between the bullet and the body armor cannot be effectively reduced, and the collision between the bullet and the body armor is easy to produce stray bullets. Composite body armor, designed to optimize the existing body armor structure, can effectively avoid the generation of stray bullets and the risk of rib fractures caused by excessive impact force

Embodiment Construction

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

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

[0025] The bomb-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 small linear expansion coefficient. Aluminum foam as a filling material has low density and high impact absorption capacity. The purpose of this layer structure is to make the bullets collide with the body armor, and the body armor can absorb the bullets so as to avoid the genera...

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...
