1. Kevlar
The appearance of this high-performance fiber ballistic fabric greatly improves the performance of soft textile bulletproof clothing, and also improves the comfort of bulletproof clothing to a great extent. The U.S. military took the lead in using Kevlar to make spherical fabric and developed two types of bulletproof vests. The new bulletproof clothing takes Kevlar fiber fabric as the main material and bulletproof nylon cloth as the envelope. The light bulletproof vest is composed of 6 layers of Kevlar fabric, with a medium weight of 3.83kg. Compared with nylon and glass fiber bulletproof vests, the weight of bulletproof vests made by Kevlar ballistic fabric is reduced by 50%. When the mass per unit area is the same, its protective force can be increased by at least twice, and it has good flexibility.
2.UHMWPE
Ultra high molecular weight polyethylene fiber (UHMWPE), as a new bulletproof material, is a ballistic fabric spun from polyethylene with a relative molecular weight of 1 million to 5 million. It is the ballistic fabric with the highest strength and the lightest proportion in the world. Its strength is 15 times higher than that of steel wire, but it is very light, up to 40% lighter than aramid and other materials.
In terms of national defense Quartermaster Equipment, due to its good impact resistance and large specific energy absorption, UHMWPE Baltic fabric can be made into protective clothing materials, helmets and bulletproof materials in military, such as armored protective plates of helicopters, tanks and ships, protective shell covers of radar, missile covers, bulletproof clothing, stab proof clothing, shields, parachutes, etc, Among them, the application of bulletproof clothing is the most eye-catching.
3. Carbon nanotubes
Carbon nanotubes are one of the best ballistic fabrics with mechanical properties found so far. They have very high tensile strength and elongation at break. Its density is only one sixth to one fourth of that of steel. The tensile strength per unit mass is 276 times that of steel. The elastic modulus parameter of carbon nanotubes is 2.4 times stronger than that of Kevlar. As a balistic fabric, the comprehensive properties of carbon nanotubes far exceed any other materials found and manufactured by human beings.
