Description
Technical Field
The embodiment of the invention relates to the field of bulletproof equipment, in particular to a bulletproof vest with strong electromagnetism repulsion.
Background
With the development of science and technology and the rise of novel composite materials, the performance of the bulletproof vest serving as a protective article is greatly improved since the emergence of the bulletproof vest, and the core performance which the bulletproof vest should have first is bulletproof performance serving as a protective article. Meanwhile, as a functional garment, the garment also has certain performance for the garment. The bulletproof performance of the bulletproof vest is mainly embodied in two aspects: on one hand, the anti-explosion sheet is an anti-explosion sheet, and high-speed fragments generated by explosion of various explosives such as bombs, land mines, shells, grenades and the like are one of main threats on a battlefield; another aspect is prevention of non-penetrating injury: the bullet, after hitting the target, generates a very large impact force, which is often fatal to the human body.
Body armor (Bulletprofvest) is used for protecting the damage of bullets or shrapnel to human bodies, and the composite body armor developed up to now is generally applied, namely, a light ceramic plate is used as an outer layer, and high-performance fiber fabrics such as Kevlar and the like are used as an inner layer. The soft bulletproof inner layer, such as single-layer weftless cloth, can be used as a main structure of the soft bulletproof garment after being laminated, and can be used as a hard bulletproof material for bulletproof reinforcing insertion plates and the like after being pressed in multiple layers, wherein most of the energy of the bullet body is absorbed by breaking the fiber at the impact point or the fiber nearby the impact point through overstretching or puncturing; and fiber breakage hardly occurs in the needle-punched non-woven felt, and the needle-punched non-woven felt is composed of a large number of short fibers, has no interweaving points, and hardly has fixed point reflection of a strain wave. The ballistic effectiveness depends on the diffusion rate of the ballistic energy in the felt. The hard bulletproof outer layer absorbs the impact energy of the bullet by the dent and the rupture of the bullet after the bullet hits. Although the soft and hard combined scheme does improve the bulletproof effect of the bulletproof garment to a great extent, the bulletproof effect of the bulletproof garment with only one hard bulletproof layer and one soft bulletproof layer is still insufficient.
