Embodiment 1

[0017] A carbon fiber composite plate molding process, comprising the following steps:

[0018] a. Lay-up: Lay the carbon fiber filaments in parallel on the lamination plate of the flat vulcanizing machine in the way of horizontal → vertical → horizontal. The ratio of the number of layers of the carbon fiber filaments in the horizontal direction and the vertical direction is 8: 7, and the carbon fiber filaments are 8K fibers Silk.

[0019] b. Glue brushing: Use a roller to repeatedly brush epoxy resin on the surface of the layup. The carbon fiber filaments are completely absorbed by the epoxy resin, and the excess epoxy resin is exported. The ambient temperature for epoxy resin coating is 35°C .

[0020] c. Pressing: Continue to pressurize the carbon fiber filaments after brushing to 12MPa, and keep the pressure for 3 hours to make it a carbon fiber composite board with uniform thickness.

[0021] d. Curing: heating and curing the pressed carbon fiber composite panel. The h...

Abstract

The invention discloses a carbon fiber composite board forming process, and relates to the technical field of carbon fiber composite structural member forming. The carbon fiber composite board comprises the following steps of layer paving, glue brushing, pressing, curing and demolding to obtain the carbon fiber composite board. The carbon fiber composite board forming process is simple, material waste and environmental pollution are avoided in the forming process, the prepared carbon fiber composite board is high in volume density, high in bearing capacity, smooth in surface, free of cracks and wrinkling and folding.

Description

technical field [0001] The invention relates to the technical field of forming carbon fiber composite structural parts, in particular to a carbon fiber composite plate forming process. Background technique [0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. It is formed by stacking organic fibers such as flake graphite microcrystals along the fiber axial direction. Microcrystalline graphite material obtained by processing. Carbon fiber is "soft on the outside and rigid on the inside". It is lighter in weight than metal aluminum, but its strength is higher than that of steel. It is also fatigue-resistant, corrosion-resistant, and X-ray transparent. 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. ...
