Description

technical field [0001] The invention relates to a method for preparing a coating on the surface of carbon fiber cloth, in particular to a method and device for preparing a coating by cathode plasma electrolysis assisted by copper tubes, and belongs to the technical field of carbon fiber cloth surface modification. Background technique [0002] Carbon fiber is a microcrystalline graphite material fiber obtained by carbonizing and graphitizing organic fibers (polyacrylonitrile fibers, pitch fibers, viscose fibers or phenolic fibers, etc.). The carbon content of carbon fiber is more than 90%, and it is black. It has high strength, high specific modulus (the strength is 10 times that of steel, and the quality is only half of aluminum), light weight, corrosion resistance, fatigue resistance, and small thermal expansion coefficient. , small friction coefficient, high and low temperature resistance and other superior properties, it is widely used in engineering. Carbon fiber is ge...
