The three major high-performance fibers in the world today are: aramid fiber, carbon fiber, and ultra-high molecular weight polyethylene fiber, and ultra-high molecular weight polyethylene fiber (UHMWPE) has the characteristics of high specific strength and specific modulus. Performance composite products (sports equipment, ropes, etc.) have been widely used in various industries. At present, China’s ultra-high molecular weight fiber technology has also made great progress in recent years. The glass fiber reinforcement is the main material, and in the past few years, it has been promoted to a certain extent due to the comprehensive properties of aramid fiber. However, due to various factors such as cost, the market of aramid fiber (KEVLAR) reinforced optical cable reinforced core is in the Gradually shrinking, and more manufacturers and users will focus on UHMWPE fiber, because the ultra-high molecular weight polyethylene fiber reinforced core has moderate cost and better performance. However, due to the various characteristics of the fiber (including temperature resistance, etc.), higher requirements are placed on the processability and wettability of the resin. The company has successfully applied vinyl resin to untreated resin many years ago. On the basis of the surface aramid fiber pultrusion process, vinyl resin suitable for ultra-high molecular weight fiber pultrusion has also been introduced, and has been applied in batches.The cost of this reinforcing core is 40% lower than that of aramid fiber, but Has higher flexural and tensile properties.
