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.

Description

TECHNICAL FIELD

[0001] The present invention relates to a composite ultra-high molecular weight polyethylene fiber and a preparation method thereof, and belongs to the technical field of high performance fibers.BACKGROUND

[0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is also known as ultra-high strength polyethylene (UHMWPE) fiber, ultra-high modulus polyethylene (UHMWPE) fiber. Due to its unrivaled ultra-high tensile strength, UHMWPE can be used to produce fibers with ultra-high modulus of elasticity and strength by gel spinning, and the resulting fibers have a tensile strength of up to 3-3.5 Gpa, and a tensile elastic modulus of up to 100-125 GPa; and the fiber strength of which is the highest of all fibers that have been commercialized to date, 4 times larger than carbon fiber, 10 times larger than steel wire, and 50% larger than aramid fiber. It is widely used in military equipment, aerospace, marine operations, sports equipment and other fields.
