Example Embodiment

[0019] The specific implementation of the present invention will be described in detail below with reference to examples. It should be understood that the examples are used to illustrate the present invention and not to limit the present invention. The scope and core content of the present invention are determined based on the claims.

[0020] 1. Design the mold according to the product size.

[0021] 2. Design the size of the carbon fiber cloth according to the mold size, and set the cutting point (that is, the cutting and folding position, which helps the product size to be more accurate).

[0022] The carbon fiber cloth used is made by infiltrating resin and carbon fiber and then curing. The carbon fiber cloth is formed by a number of carbon fiber bundles forming a staggered angle of 0°, ±20°, and ±45°. 0° yarn can reinforce the rigidity of the carbon fiber yarn; 20° can increase the tensile strength of the carbon fiber yarn; 45° can reinforce the cutting opening and increase t...

Abstract

The invention relates to carbon fiber cloth and a pasting method of a carbon fiber composite material composed of the carbon fiber cloth. The carbon fiber cloth is formed by a plurality of carbon fiber bundles according the to texture angles of 0, +/-20 degrees and +/-45 degrees in an intersecting manner; and then the carbon fiber cloth is subjected to layer laying by adopting an overlap joint andfolding overlapping manner, then demolding is performed, and curing is performed. The carbon fiber cloth with the special texture angles is adopted for the pasting method, various layers of compositematerials are pasted more closely by adopting the overlap joint and folding overlapping layer laying manner, it is not likely to generate bubbles during hot pressing forming, stress of various positions is balanced, and therefore the product performance is improved.

Description

technical field [0001] The invention relates to the technical field of hot pressing forming technology of composite materials, in particular to a carbon fiber cloth and a bonding method of carbon fiber composite materials formed by it. Background technique [0002] The hot press molding process of carbon fiber composite products is as follows: after heating the processing mold, put the preformed carbon fiber composite material into the mold cavity, fix the mold on the heating plate with pressure, and control the melting temperature and time of the resin to After melting, harden, cool, and then take out the finished model. Usually, before thermoforming, multi-layer carbon fiber cloth of a certain shape and size is superimposed and flattened on the designed model, demoulded, and then thermoformed. There is following technical problem in above-mentioned technique: [0003] 1. Directly superimpose multiple layers of carbon fiber cloth, the fit is not tight, and there are air b...
