Electric casting manufacturing device and process of carbon fiber reinforced metal

Abstract

The invention relates to an electric casting manufacturing device and a process of carbon fiber reinforced metal. Carbon fibers are wound on the surface of a cathode core mold under the condition of flexible pressing for electric casting formation. Under driving of a rotating motor and a guider, the carbon fibers are continuously wound and fully paved on the whole cathode core mold, and meanwhile, metal nickel is continuously deposited on the cathode core mold and the carbon fibers. In the process, a flexible pressing device is always tightly bonded on the surface of the cathode core mold. A water sucking material on the surface of the flexible pressing device can permeate electric casting liquid into the carbon fiber bundle to increase compactness of a prepared electric casting layer; and the flexible pressing device can remove hydrogen bubbles generated by the reaction and other impurities through the effects of extrusion and friction on the cathode core mold and the carbon fibers. The device needed by the process comprises an electric casting system, a carbon fiber winding system and a flexible pressing system. The device and the process can prominently reduce internal holes and surface defects of a carbon fiber reinforced metal electric casting layer, and prominently improve the quality and the mechanical performance of the prepared carbon fiber reinforced metal electric casting layer.

Description

technical field [0001] The invention relates to the field of electroforming technology, in particular to an electroforming manufacturing process and device for carbon fiber reinforced metal. Background technique [0002] As a precision special processing method, electroforming technology uses the principle of electrodeposition of metal ions on the surface of the cathode to manufacture parts.

[0003] There are still some problems that have not been solved in the traditional electroforming manufacturing technology. For example, the thickness uniformity of the electroformed layer is poor, defects are prone to occur, and the mechanical properties are not ideal. Among them, the mechanical properties have a great influence on the development of electroforming ...

AI Technical Summary

Problems solved by technology

[0006] Commercially available carbon fiber threads are bundled fibers composed of hundreds or thousands of carbon fiber monofilaments. During the electroforming process, it is difficult for the electroforming solution to penetrate into the bundled fibers so that each carbon fiber monofilament is in contact with the electroforming solution, resulting in The prepared carbon fiber reinforced electroforming layer has a large number of voids inside and many carbon fiber monofilaments are in a suspended state, which does not play a reinforcing role
