Abstract
The present invention provides a composite ultra-high molecular weight polyethylene fiber and a preparation method thereof, wherein the method comprises mixing glass fiber, graphene slurry, UHMWPE powder and white oil, and then swelling to a molten state, then cooling into a gel-spun, and finally making the fiber from the gel-spun. The method of the present disclosure not only can solve the problem that the glass fiber has poor dispersibility in the case of high viscoelasticity of the ultra-high molecular weight polyethylene, but also can improve the cut resistance of the ultra-high molecular weight polyethylene fiber on the basis of ensuring the flexibility of the yarn.
