The quality ballistic fabric from hard to soft bulletproof materials, changed people's understanding of the mechanism of bulletproof, and greatly expanded the space of bulletproof materials; the latter accelerated the development of bulletproof materials in the direction of lighter weight and comfort. quality ballistic fabric is very good.
At present, the high-performance fibers that are industrialized and mass-produced mainly include para-aramid fibers (aramid fibers), ultra-high molecular weight polyethylene fibers and carbon fibers. The first two are widely used in the field of bulletproof. The specific strength and specific modulus of aramid fiber are 10 times that of steel, while the specific strength of ultra-high molecular weight polyethylene fiber is about 1.5 times higher than that of aramid fiber. 

A single fiber or bundle of filaments cannot play the role of bulletproof. Only when the fibers are arranged and integrated according to a certain rule, can they effectively resist the attack of bullets or fragments. quality ballistic fabric are fixed together by woven fabric through a certain sewing process, or laminated together by multiple layers of non-weft cloth. Its bulletproof mechanism is different from hard bulletproof materials. 
The latter uses its own hardness to change the shape of warheads or fragments, reduce kinetic energy, and play a bulletproof effect. The quality ballistic fabric absorbs the energy of the projected object through the deformation of the fiber to achieve the purpose of bulletproof. When the warhead or fragment hits the fabric, there are two basic mechanisms of tensile failure and shear failure. The occurrence of these two mechanisms is mainly related to the shape, material and speed of bullets or fragments. When bullets with a conical head are shot into the fabric, they are mainly tensile failure; for high-speed irregular fragments, shearing is used. Cut damage mainly.
