Carbon fiber forming mold and method

Abstract

The invention discloses a carbon fiber forming mold and method. The forming mold comprises a mold frame and a carbon fiber base material with a surface coated with resin or the surface mixed with theresin for winding, wherein the mold frame comprises a plurality of mold pieces and fixing pieces, the plurality of mold pieces are distributed at intervals along the circumferential direction of the fixing pieces, and mold pieces are detachably connected with the fixing pieces correspondingly; the method comprises the following steps that 1) the carbon fiber base material with the surface coated with the resin or the surface mixed with the resin winds around the mold frame; 2) the whole mold and the wound carbon fiber base material are placed together in a heating device for heating; 3) the mold is taken out after the carbon fiber base material is solidified; and 4) the mold pieces of the mold frame are disassembled to obtain a carbon fiber product which is in a curling shape and in a three-dimensional contouring. According to the carbon fiber forming mold and method, the carbon fiber product which is in the curling shape and the three-dimensional contouring can be obtained, and the carbon fiber product has relatively complicated spatial form and is attractive in appearance; and the method has the characteristics of ingenious design, simple process, low cost and the like.

Description

technical field [0001] The invention relates to a forming die, in particular to a carbon fiber forming die and method. Background technique [0002] At present, the existing carbon fiber molding methods mainly include the following two types: [0003] 1) Use carbon fiber substrate cloth, the surface is covered with resin, put it into the metal mold cavity and heat it to a certain temperature to solidify and form. [0004] 2) Use carbon fiber base cloth to form a wrapping on the surface of a specific fixture, mix resin on the surface, and heat to a certain temperature to cure and shape. [0005] The shape of carbon fiber products formed by the above existing molding methods is relatively simple, and complex spatial shapes cannot be formed, or the molding cost is relatively high. Contents of the invention [0006] The invention provides a carbon fiber molding die and method, which overcomes the shortcomings of the carbon fiber molding technology in the prior art. [0007]...
