Example Embodiment
[0030] Such as figure 1 As shown, the method for screening the surface forming performance of a carbon fiber composite material mold of the present invention has the following steps:
[0031] (1): Use a CNC machine tool to process the master mold according to the parabolic equation to form a molding surface with a certain surface accuracy and surface roughness;
[0032] (2): Lay the mold prepreg on the surface of the master mold in step 1. During the prepreg placement process, the prepreg is pre-pressed according to the pre-pressing system of the mold prepreg resin system; After the prepreg is placed, the composite material mold is cured and formed in an autoclave or oven according to the curing system of the mold prepreg resin system;
[0033] (3): After the composite material mold completes the curing and forming of step two on the master mold, the composite material mold is released from the master mold to ensure that there is no delamination and cracking damage during the demold...
