Carbon fiber member manufacturing method and carbon fiber member manufactured by method

Abstract

The present invention discloses a method for manufacturing a carbon fiber component, including: placing a film with a texture on a first side surface into a mould, where a second side surface of the film abuts against an inner wall of the mould; injecting melted carbon fiber composite plastic into the first side surface through an injection port of the mould to obtain a component in a first shape; and obtaining a component in a second shape from the component in the first shape by using a material removal technique. Compared with the prior art, with the manufacturing method provided in the present invention, on the basis of ensuring a use strength requirement of a component, processing efficiency may be effectively increased; and moreover, a surface of a carbon fiber component manufactured by using this method has a carbon fiber texture that can bring a favorable appearance effect. On this basis, the present invention further provides a carbon fiber component manufactured by using this manufacturing method.

Description

technical field [0001] The invention relates to the technology of carbon fiber components, in particular to a method for manufacturing carbon fiber components and the carbon fiber components produced by the method. Background technique [0002] With the development of science and technology and the improvement of application requirements, all kinds of electronic products are constantly being introduced, and gradually showing a trend of thinning and thinning; at the same time, under the premise of the same performance of the whole machine, a good product appearance effect will directly affect the user's experience. choose. [0003] For example, the current mobile phone has a large screen and thinner and lighter as the main development trend. As we all know, the use of a large screen and thinner design will inevitably reduce the strength of the mobile phone shell, so the current design usually uses materials with higher specific strength to make the mobile phone shell.

Problems solved by technology

However, this process is limited by its own characteristics and has the following insurmountable defects: a. The multi-layer carbon fiber cloth press molding takes a long time (hot pressing + cold pressing), the production capacity is low, and the cost is high; b. Since the multi-layer carbon fiber cloth passes through It is bonded with thermosetting glue, so the buckle structure obtained by processing is brittle and insufficient in strength; c. During the pressing and forming process of the component, the carbon fiber cloth will be distorted due to stretching, resulting in uneven appearance of the carbon fiber texture on the surface of the component, which affects the appearance quality
