Description

technical field [0001] The invention provides a device and method for continuously compounding electroplated metal and nano particles on the surface of carbon fibers. Background technique [0002] Carbon fiber is one of the most important reinforcing fibers in composite materials. In carbon fiber reinforced metal matrix composites, a very critical factor is the wettability between the fibers and the matrix metal. In order to improve the interfacial bonding force and prevent excessive interfacial chemical reactions, it is necessary to coat the carbon fiber surface. Commonly used methods include electroless plating, electroplating, physical vapor deposition, chemical vapor deposition, ion sputtering, etc., but the chemical plating process is complicated, consumes a lot of chemicals, the equipment required for physical vapor deposition and chemical vapor deposition is expensive, and the quality of the coating needs to be improved. The electroplating method has the advantages ...
