Special personnel bulletproof vests. Mainly used for special tasks. On the basis of infantry bulletproof vests, neck protection, shoulder protection, and abdominal protection functions have been added, increasing the protection area; There are insert pockets on the front and back
Different Bulletproof Materials for Bulletproof Vests
Bulletproof vests are divided into:
1. Infantry bulletproof vests. Equipped with infantry, Marine Corps, etc., to protect personnel from various types of debris.
2. Special personnel bulletproof vests. Mainly used for special tasks. On the basis of infantry bulletproof vests, neck protection, shoulder protection, and abdominal protection functions have been added, increasing the protection area; There are insert pockets on the front and back for adding bulletproof inserts and improving bulletproof performance.
3. Artillery bulletproof vests. Mainly used by artillery during combat, it can protect against fragments and shockwave damage.
According to structural materials, bulletproof vests are divided into:
1. Soft bulletproof vests. The bulletproof layer is generally composed of multiple layers of high-strength and high modulus fiber fabrics with stitching and stitching, or directly stacked. When bullets and fragments penetrate the bulletproof layer, directional shear, tensile damage, and delamination damage occur to consume their energy.
2. Hard bulletproof vests. The bulletproof layer is usually made of laminated plates made of metal materials, high-strength and high modulus fibers, resin based composite materials heated and pressurized, bulletproof ceramics, and high-strength and high modulus fiber composite plates. The bulletproof layer made of metal materials mainly consumes the energy of the projectile through deformation and fragmentation of the metal material. The bulletproof layer of high-strength and high modulus fiber bulletproof laminates consumes the energy of the projectile through layering, punching, resin matrix rupture, fiber extraction, and fracture. The bulletproof layer of the composite plate made of bulletproof ceramics and high-strength high modulus fibers is used. When the high-speed projectile collides with the ceramic layer, the ceramic layer will shatter or crack and diffuse around the impact point, consuming most of the projectile's energy. Subsequently, the high modulus fiber composite plate will further consume the remaining energy of the projectile.
3. Soft and hard composite bulletproof vests. The surface layer is made of hard bulletproof material, and the inner lining is made of soft bulletproof material. When bullets and fragments hit the surface layer of the bulletproof vest, the bullets, fragments, and hard materials on the surface layer undergo deformation or fracture, consuming most of the energy of the bullets and fragments. The soft lining material absorbs and diffuses the energy of the remaining parts of the bullet and fragments, providing cushioning and reducing non penetrating damage.
