The three major high-performance fibers in the world today are: aramid, carbon fiber, ultra-high molecular weight polyethylene fiber, and ultra-high molecular weight polyethylene fiber (UHMWPE) due to its high specific strength and specific modulus, is used in military, aerospace, high 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 been developed by leaps and bounds. At present, in the communications industry, the main The main material is glass fiber reinforced. In the past few years, it has also been promoted due to the comprehensive performance of aramid fiber. However, due to various factors such as cost, the market for aramid fiber (KEVLAR) reinforced fiber optic cable reinforced core Gradually shrinking, and more manufacturers and users focus on UHMWPE fiber, because UHMWPE fiber reinforced core has moderate cost and better performance. However, due to the various characteristics of the fiber (including temperature resistance, etc.), higher requirements for the processability and wettability of the resin have been put forward. Our company has matured and successfully applied vinyl resins to Treated surface aramid fiber pultrusion process, on this basis, introduced a vinyl resin suitable for ultra-high molecular weight fiber pultrusion, and was applied in batches. This kind of reinforced core is 40% lower than the cost of aramid fiber, but Has higher flexural and tensile properties.
