Bulletproof vest is a kind of protective clothing used to reduce bullet damage like armor. They are worn by the police and the army. Fundamentally speaking, there are two bulletproof mechanisms: one is to bounce off the fragments formed after fragmentation of the projectile; the other is to dissipate the kinetic energy of the warhead through bulletproof materials. Studies have shown that there are five ways for the software bulletproof vest to absorb energy. Let’s follow the editor of PASGT helmet Manufacturers china to have a brief look!
1. The deformation of the fabric: including the deformation of the bullet incident direction and the stretching deformation of the area near the incident point.
2. Fabric destruction: including fiber fibrillation, fiber breakage, yarn structure disintegration and fabric structure disintegration.
3. Thermal energy: Energy is dissipated in the form of heat through friction.
4. Acoustic energy: the energy consumed by the sound of the bullet hitting the bulletproof layer.
5. Deformation of the projectile. The bulletproof mechanism of the soft and hard composite body armor developed to improve the bulletproof capability can be summarized by "soft and hard". When a bullet hits the body armor, it is the hard bulletproof material such as steel plate or reinforced ceramic material that acts 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 bulletproof vest, 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 the introduction of the bulletproof vest of PASGT helmet Manufacturers china. I hope you can learn more about it.
