Manufacturing process of carbon fiber automobile door outer plate

Abstract

The invention discloses a manufacturing process of a carbon fiber automobile door outer plate. The manufacturing process comprises the following steps of 1) manufacturing a special forming mold; 2) laying carbon fiber cloth; 3) closing the mold, injecting glue, and simultaneously vacuumizing; 4) curing and maintaining the pressure; and 5) demolding and taking out. In the forming mold, a lower mold(2) is provided with a knife edge (4) for cutting flash generated during forming at the edge of a cavity (3), and the forming mold further comprises a vacuumizing device. By adopting the manufacturing process, one-time compression molding can be realized through the mold without subsequent cutting of an extension edge and polishing of a cutting edge, so that the process is simple, the productionefficiency is high, and meanwhile, the product quality can be guaranteed.

Description

technical field

[0001] The invention relates to the technical field of forming carbon fiber products, in particular to a manufacturing process of a carbon fiber automobile door outer panel. Background technique

[0002] Existing auto parts are developing in the direction of light weight. It is necessary to ensure its strength and reduce its weight as much as possible. For the outer panel of the automobile door, it is preferred to have strength and lightness. Therefore, carbon fiber materials are usually used for manufacturing, because carbon fiber has the advantages of lighter weight than aluminum, higher strength than steel, corrosion resistance, high temperature resistance, and high modulus. At present, there are many methods of manufacturing carbon fiber products, and the most suitable method for making automobile door outer panels is the compression molding method. This compression molding method is to put the carbon fiber material that has been pre-impregnated with re...
