(Summary description)In practice, the material used for bulletproof vest does not allow excessive deformation, so the fiber used for bulletproof vest needs to have a high resistance to deformation at the same time, that is, high modulus. The influence of the structure of the yarn on the ballistic resistance is due to the difference in the single fiber strength utilization rate and the overall elongation deformation ability of the yarn due to different yarn fabrics.

Information

In practice, the material used for bulletproof vest does not allow excessive deformation, so the fiber used for bulletproof vest needs to have a high resistance to deformation at the same time, that is, high modulus. The influence of the structure of the yarn on the ballistic resistance is due to the difference in the single fiber strength utilization rate and the overall elongation deformation ability of the yarn due to different yarn fabrics. The breaking process of the yarn depends on the breaking process of the fiber, but because it is an aggregate, there is a big difference in the breaking mechanism. If the fineness of the fiber is fine, the entanglement in the yarn is tighter, and the force is more uniform, thus increasing the strength of the yarn. In addition, the straightness and parallelism of the fiber arrangement in the yarn, the number of transfers of the inner and outer layers, and the twist of the yarn have an important influence on the mechanical properties of the yarn, especially the tensile strength and elongation at break. In addition, due to the interaction between the yarn and the elastic body during the bombardment process, the surface characteristics of the yarn will have the effect of strengthening or weakening the above two effects. The presence of oil and moisture on the surface of the yarn will reduce the resistance of bullets or shrapnel to penetrate the material, so people often need to clean and dry the material, and seek ways to improve the penetration resistance. Synthetic fibers with high tensile strength and high modulus are usually highly oriented, so the fiber surface is smooth and the coefficient of friction is low. When these fibers are used in bulletproof fabrics, the ability to transfer energy between the fibers is poor after bombardment, and the stress wave cannot spread quickly, thereby reducing the ability of the fabric to block bullets.
The above is the introduction of bulletproof visor Manufacturers china editor: You can learn more about the influencing factors of bulletproof vest.
