The Bulletproof Ability of UD Fabric is Affected by UHMWPE Fiber

The influence of the structure of UD fabric on its bulletproof ability is due to the differences in single fiber utilization and overall elongation and deformation ability caused by different UHMWPE fibers.

The Bulletproof Ability of UD Fabric is Affected by UHMWPE Fiber

The influence of the structure of UD fabric on its bulletproof ability is due to the differences in single fiber utilization and overall elongation and deformation ability caused by different UHMWPE fibers. The fracture process of UD fabric first depends on the fracture process of UHMWPE fibers. However, due to its aggregation, there are significant differences in the fracture mechanism. The fine fineness of the bulletproof material fibers results in a tighter fit in the UD fabric and a more uniform force distribution, thereby improving the strength of the UD fabric. In addition, the straightness and parallelism of fiber arrangement, the number of inner and outer layer transfers, and yarn twist all have important effects on the mechanical properties of UD fabric, especially tensile strength and elongation at break.

In addition, due to the interaction between fibers and the projectile during the impact process, the surface characteristics of UD fabric will either enhance or weaken the above two effects. The presence of UD fabric surface oil and moisture can reduce the resistance of bullets or shrapnel penetrating materials, so people often need to clean and dry the materials and seek ways to improve penetration resistance. Synthetic fibers with high tensile strength and high modulus are usually highly oriented, resulting in a smooth surface and low friction coefficient. When these fibers are used in bulletproof fabrics, their ability to transfer energy between fibers after being hit by bullets is poor, and stress waves cannot spread quickly, thereby reducing the fabric's ability to block bullets.

Longkui possesses professional skills and capabilities in researching and producing UHMWPE fibers of different specifications, including breaking tension, modulus, and elongation. Based on the different requirements of customers for the weight, bulletproof level, and bullet defense of bulletproof vests, helmets, plates, and other products, we will choose different specifications of UHMWPE fibers to produce different styles of UD fabrics to meet their requirements.
