Abstract
Single ultra-high molecular weight polyethylene (UHMWPE) fiber was modified by modified nano-graphite (NG) in wear resistance. Wear resistance, tensile strength, thermogravimetric analysis (TGA) were used to characterize the effect of modified NG on the properties of UHMWPE fiber. The results showed that with the increasing content of modified NG, the wear resistance of UHMWPE fiber was enhanced and its tensile strength was decreased. Considering the tensile strength and wear resistance of fiber, the optimum content of modified NG in UHMWPE fiber was around 0.58%. At this content, the wear resistance and thermal decomposition temperature of UHMWPE fiber were increased 1.88 times and 50°C respectively than pure UHMWPE fiber.
