There are basically two bulletproof mechanisms of the Low price bulletproof jacket: one is to bounce off the fragments formed by the fragmentation of the bullet; the other is to dissipate the kinetic energy of the bullet through the bulletproof material. This Low price bulletproof jacket and later similar hardware Low price bulletproof jackets play a bulletproof role by popping off the bullet or shrapnel, or breaking the bullet to consume and decompose its energy. The soft low price bulletproof jacket with high-performance fiber as the main bulletproof material, its bulletproof mechanism is mainly the latter, that is, the use of high-strength fiber as the raw material to "catch" bullets or shrapnel to achieve the purpose of bulletproof.

When the bullet hits the Low price bulletproof jacket, the hard bulletproof material such as steel plate or reinforced ceramic material will act first. During this moment of contact, both bullets and hard bulletproof materials may deform or break, consuming most of the bullet's energy. The high-strength fiber fabric is used as the liner and second line of defense of the Low price bulletproof jacket, absorbs and diffuses the energy of the remaining part of the bullet, and acts as a buffer, thereby reducing non-penetrating damage as much as possible. In the two bulletproof processes, the previous one played the main energy absorption function, which greatly reduced the penetration of the projectile, which is the key to bulletproof.
The above is a brief introduction to some relevant knowledge about Low price bulletproof jacket.
