Abstract

The invention discloses a method and system for continuously electroplating metal on the surface of carbon fiber. The method comprises the steps that carbon fibers continuously pass through a high-temperature glue removing device provided with an airflow filament spreading mechanism to be subjected to glue removing treatment, and pretreated carbon fibers are obtained; and carrying out electroplating treatment on the pretreated carbon fiber to obtain the metal composite carbon fiber. According to the method provided by the invention, the degumming effect on the surface of the carbon fiber is good, the electroplating dispersion is good, continuous and uniform metal electroplating can be realized under the condition that the original mechanical strength of the carbon fiber is maintained, and the electroplated carbon fiber does not have a black core phenomenon.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber metallization, and in particular relates to a method and a system for continuously electroplating metal on the surface of carbon fibers. Background technique [0002] Nickel-plated carbon fiber is a high-conductivity lightweight fiber material that uniformly coats the metal coating on the surface of carbon fiber on the basis of continuous nano-modification of the carbon fiber surface. Compared with traditional electromagnetic shielding materials, it has stronger corrosion resistance and lighter weight. , higher strength, and unique electrical and magnetic properties, it has important applications in aerospace, military equipment, rail transit, communication electronics, and new energy vehicles. [0003] The surface of the carbon fiber precursor will be coated with organic glue before leaving the factory, so that the surface of the carbon fiber is smooth and easy to wind. But the existence of...
