Problems solved by technology

[0004] For carbon fiber parts such as cavities or pipe fittings, the processing accuracy is very high. If there is a dimensional deviation, mold clamping failure or obvious seams will occur when two carbon fiber parts are molded together; the existing hot pressing process, the dimensional accuracy of carbon fiber parts At about 1mm, the two carbon fiber parts after mold closing usually have obvious seams, and usually need to be polished after gluing, and the grinding will destroy the surface texture of the carbon fiber parts, and the customer's sensory experience is not good, which will directly affect the selling price of the product

Embodiment Construction

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] see figure 1 , the embodiment of the present invention provides a method for preparing carbon fiber parts by hot pressing, and the carbon fiber parts are specifically pipe fittings, and the method includes:

(1) Foaming molding: a preformed mold is obtained by foaming molding of self-foaming materials.

[0021] (2) Foaming and baking: bake the preformed mold at 65° C. for 80 minutes and apply mold release oil.

[0022] (3) Cutting of carbon cloth: The carbon cloth pre-impregnated with resin is cut according to the design size. The carbon cloth is 6K carbon cloth and its resin content is 40%, and the resin is epoxy medium temperature resin.

[0023] (4) Lay-up: Lay the carbon cloth obtained in step (3) on the pre-forming mold while it is still hot, the ...

Abstract

The invention discloses a method for preparing a carbon fiber part by adopting a hot pressing method, and belongs to the technical field of carbon fiber products. The method comprises the steps of foam forming, foam baking, carbon cloth cutting, layering, vacuum bag filling, hot press forming, demolding and mold closing. According to the method, the machining precision can be below 0.4 mm, die assembly is facilitated, no obvious joint exists after die assembly, transition at the joint is natural, smooth transition is basically achieved, and the appearance is attractive.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber products, and particularly relates to a method for preparing carbon fiber parts by a hot pressing method. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the quality of automobiles. In order to adapt to the development of the times and the needs of consumers, automobile manufacturers around the world are constantly innovating, not only to improve the efficacy and quality of auto parts, but also to carry out various tooling and production lines for the production of auto parts. Improvements to increase productivity and reduce cost savings. At present, the structural parts and semi-structural parts of the automobile body are still metal products. In order to realize the lightweight of the automobile, a new type of carbon fiber material is used to replace the structural parts and semi-structural parts of the automobil...
