摘要： The present invention relates to the field of manufacture of polymer materials, and more particularly to an ultra-high molecular weight polyethylene (UHMWPE) composition and a cut resistant and creep resistant fiber prepared therefrom. The ultra-high molecular weight polyethylene composition comprises the following components: modified graphene, modified silicon carbide whisker, and ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene composition provided by the present invention has superior cut resistance, high strength and high modulus. By regulating the morphology of silicon carbide, the type of a coupling agent, the mixing ratio and so on, not only cut resistance, high strength and high modulus can be provided, but also creep resistance can be improved. Meanwhile, adding the coupling agent into the formulation makes silicon carbide being wrapped, so that direct contact with human body can be avoided, thus ensuring safety without toxic side effects while improving product performance.
