Bulletproof vests are divided into structural materials. Do you know which ones are available? Let’s follow the editor of ballistic PE panel Manufacturers china to have a brief look at it!
1. Software bulletproof vest. The bulletproof layer is generally made of multiple layers of high-strength and high-modulus fiber fabrics quilted or directly laminated. When bullets and fragments penetrate the bulletproof layer, they will produce directional shear, tensile failure and delamination failure, thereby consuming their energy.

2. Hardware bulletproof vest. The bulletproof layer is usually made of metal materials, high-strength and high-modulus fiber laminates made of resin-based composite materials heated and pressurized, bullet-proof ceramics, and high-strength and high-modulus fiber composite boards. The bulletproof layer of metal material is used to consume the energy of the projectile mainly through the deformation and fragmentation of the metal material. The bulletproof layer of the high-strength and high-modulus fiber bulletproof laminate consumes the energy of the projectile through delamination, punching, resin matrix rupture, fiber extraction and fracture. The bulletproof layer of bulletproof ceramics and high-strength and high-modulus fiber composite board is used. When the high-speed projectile collides with the ceramic layer, the ceramic layer breaks or cracks and spreads around the impact point to consume most of the projectile’s energy. The modulus fiber composite board further consumes the remaining energy of the projectile.
3. Flexible and hard composite bulletproof vest. The surface layer is made of hard ballistic materials, and the inner lining is made of soft ballistic materials. When bullets and fragments hit the surface layer of bulletproof vest, the bullets, fragments and the hard materials of the surface layer are deformed or broken, consuming most of the energy of the bullets and fragments. The inner soft material absorbs and diffuses the energy of the remaining parts of the bullets and fragments, and plays a role of buffering and reducing non-penetrating damage.
The above is the editor of ballistic PE panel Manufacturers china telling about the structural material classification knowledge of bulletproof vest. I hope you can learn more about it.
