Bulletproof vest is a kind of protective clothing used to reduce bullet damage like armor. From the point of view of materials, body armor can be divided into three types: soft, hard and soft and hard composite. The material of soft body armor is mainly made of high-performance textile fibers. These high-performance fibers are much higher than the energy absorption capacity of general materials and endow the body armor with bullet-proof function. And because this kind of body armor generally adopts the structure of textiles, it has considerable The softness is called soft body armor. So do you know about its bulletproof effect? Let’s follow the editor of Ballistic PE panel Manufacturers china to have a simple look!

Its bulletproof effect mainly depends on the following aspects: fiber tensile strength, fiber elongation at break and work at break, fiber modulus, fiber orientation and stress wave transmission speed, fiber fineness, fiber assembly method, unit Area fiber weight, yarn structure and surface characteristics, fabric organization structure, fiber mesh layer thickness, number of mesh layers or fabric layers, etc. The performance of the fiber material used for impact resistance depends on the breaking energy of the fiber and the transmission speed of the stress wave. The stress wave is required to spread as quickly as possible, and the fracture energy of the fiber under high-speed impact should be as high as possible. The tensile rupture work of a material is the energy that the material has to resist damage by external forces, and it is a function related to tensile strength and elongation deformation. Therefore, theoretically, the higher the tensile strength, the stronger the elongation deformation ability of the material, the greater the potential for energy absorption.
