Abstract

The invention relates to a preparation method of a carbon fiber reinforced carbon powder / ultra-high molecular weight polyethylene composite material. The preparation method comprises the following steps of: mixing ultra-high molecular weight polyethylene powder and charcoal in distilled water; placing a mixed solution in a grinding machine for grinding, and removing water by suction filtration; adding an appropriate amount of short carbon fiber, and fully and uniformly mixing in an ultra-high speed stirring machine to obtain a suspension in a molten state; removing the water, then placing the mixture of carbon fiber / ultra-high molecular weight polyethylene / charcoal powder and an appropriate amount of coupling agent in a drying box for drying; breaking into powder; and adding into a twin-screw extruder for mixing and compounding, and molding by extrusion. The preparation method has the advantage of solving the problems of too light weight, easiness in agglomeration, difficulty in dispersion and difficulty in compounding of carbon fiber and carbon powder / ultra-high molecular weight polyethylene during the melting and compounding processes. The composite material prepared by the preparation method disclosed by the invention has a smooth surface, can be bent arbitrarily without being fractured, has very high tensile strength and tensile elastic modules, and further becomes a high-performance composite material with extensive application prospects.
