Bulletproof composite material and body armor

Abstract

The invention belongs to the technical field of bullet prevention, and particularly relates to a novel bulletproof composite material. The novel bulletproof composite material comprises a soft bulletproof layer and a torsion double-layer graphene layer arranged on the side of the bullet facing face of the soft bulletproof layer. The torsion angle between two layers of single-layer graphene of thetorsion double-layer graphene layer is 4.44-10.20 degrees or 15.31-28.35 degrees. The invention further provides body armor prepared through the bulletproof composite material. According to the provided bulletproof composite material, the bullet facing face of the soft bulletproof layer is covered with the torsion double-layer graphene layer with a certain torsion angle, lower-layer soft bulletproof layer materials are protected, meanwhile, deformation of the lower-layer soft bulletproof layer materials is driven, the lower-layer soft bulletproof layer materials absorb more energy, so that thebulletproof performance of the bulletproof composite material is greatly improved, and the integral bulletproof performance of the body armor is improved. Meanwhile, through inner-layer soft bulletproof layer materials, deformation of the torsion double-layer graphene layer is hindered, and torsion double-layer graphene is protected as well.

Description

technical field [0001] The invention belongs to the field of bulletproof technology, and in particular relates to a novel bulletproof composite material and bulletproof clothing. Background technique [0002] At present, body armor is mainly divided into three types: soft body, hard body and soft-hard composite. Among them, the material of the soft body armor is mainly the composite non-weft fabric of high-performance textile fibers. When the bullet is impacted, the high-performance fiber material will be stretched and sheared by the projectile, and the impact force will be directed to the area other than the impact point. Diffusion, thereby absorbing the energy of the bullet; and the soft-hard composite body armor uses the soft bullet-proof layer as the second line of defense. The bullet first hits the hard bullet-proof layer, consumes part of the energy, and then contacts the soft bullet-proof layer to play Bulletproof effect. For soft bulletproof vests and soft and hard...
