  • Cut resistant and creep resistant UHMWPE fiber and preparation method thereof
    Patent number: 11859071
    Abstract: 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.
