The invention discloses a method and device for continuously processing the surface of carbon fiber. The device comprises a high-voltage power supply, a rack and a processing channel which is fixed on the rack; an outlet and an inlet of the channel are respectively provided with a conductive guide roller, and the conductive guide rollers are fixed on the rack; the outer surface of the processing channel is insulated, and the processing channel is provided with an air inlet and an air outlet; a positive plate is arranged in the processing channel or the inner wall of the processing channel is configured to be the positive plate; and the positive plate is connected with the anode of the high-voltage power supply, and the guide rollers are connected with the cathode of the high-voltage power supply. The method comprises the steps of: moving the carbon fiber on two spaced conductive guide rollers, introducing oxidizing gas, then electrifying, and finally, processing the surface of the carbon fiber by using corona discharge. The method has the characteristics of high processing efficiency, high controllability and no pollution. The device is simple, small in floor space and low in cost. The carbon fiber surface energy of the processed carbon fiber is increased to ensure that enough oxygen-containing functional groups are obtained and the surface chemical energy is increased, so that the property of the carbon fiber compounding with materials such as resin, metal and the like is improved.
Description
technical field [0001] The invention relates to a method and device for carbon fiber surface treatment. Background technique [0002] Carbon fiber composite material is a high-performance material in the 21st century. Its light weight, high strength ratio, high modulus ratio, corrosion resistance, high temperature resistance and many other excellent properties make it widely used in many high-tech fields such as national defense, aerospace, wind power, automobiles, and power transmission. Applications are numerous and location is extremely important. Carbon fiber composites are limited by the interfacial properties of carbon fibers. Carbon fibers without carbon fiber surface treatment have a smooth surface and weak hydrophilicity, and cannot form a good and stable interface with the composite material matrix, which greatly reduces the overall performance of carbon fiber composite materials. Therefore, it is particularly important to carry out surface treatment on carbon fi...
