Do you know what factors affect the software bulletproof vest? Let's follow the editor of Ballistic PE panel Manufacturers china to have a simple understanding!
The key to the energy absorption of such fragments by the soft bulletproof vest lies in the fact that the fragments cut, stretch and break the yarns of the bulletproof fabric, and cause the interaction between the inner yarns of the fabric and the different layers of the fabric to cause the overall deformation of the fabric. In the above-mentioned processes, the fragments do work to the outside, thereby consuming their own energy. In the above-mentioned type of body energy absorption process, a small part of the energy is converted into heat energy through friction and into sound energy through impact. In terms of bulletproof materials, in order to meet the requirements of bulletproof vests to absorb the kinetic energy of bullets and other projectiles to a large extent, bulletproof materials need to have high strength, good toughness, and strong energy absorption capabilities. The materials used in bulletproof vests, especially software bulletproof vests, are mainly high-performance fibers. These high-performance fibers are characterized by high strength and high modulus. Although some high-performance fibers such as carbon fiber or boron fiber have high strength, they are basically not suitable for human bulletproof vest due to poor flexibility, low breaking power, difficulty in spinning and processing, and high price.

Specifically, for ballistic fabrics, 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 The fineness of the fiber, the way the fiber is assembled, the fiber weight per unit area, the structure and surface characteristics of the yarn, the structure of the fabric, the thickness of the fiber mesh layer, the number of layers of the mesh layer or the fabric layer, 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.
