Abstract

The invention discloses a molding process of a carbon fiber composite material and belongs to the technical field of molding of carbon fibers. The molding process comprises the steps of laying, gumming, heating, curing and carrying out quality inspection treatment. The molding process of the carbon fiber composite material specifically comprises the following steps: S1: laying; S2: gumming; S3: heating; S4: curing; and S5: carrying out the quality inspection treatment. The molding process is simple and efficient; raw materials of the carbon fibers can be sufficiently utilized and the wastes of the materials are not caused; the production efficiency is improved and the yield of a carbon fiber product is high; and an autoclave is used for curing, so that stripes caused by the fact that a ventilation felt and other auxiliary materials are retracted can be effectively eliminated, and cured surfaces of the materials are smooth and have no folds, and furthermore, the quality of products is improved very well.

Description

technical field [0001] The invention relates to the technical field of carbon fiber molding, in particular to a carbon fiber composite material molding process. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside", lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. Carbon fiber has many e...
