Embodiment
[0024] A carbon fiber automobile front hatch cover molding method of the present invention is applied on a molding production line of a certain automobile carbon fiber front hatch cover. The fast-curing carbon fiber prepreg is cured at a medium temperature of 130-150 ° C. The main equipment is a cutting machine (with automatic stripping) Prepreg upper / lower two-layer release paper function), press (with rapid heating / cooling function), forming mold, on the assembly line, the method of realizing the compression molding is as follows:
[0025] 1: Prepreg cutting: according to the designed shape of the front hatch cover, use a cutting machine to cut the required 4 layers of medium temperature curing carbon fiber prepreg (1 layer of 3K + 3 layers of 12K) in one piece. The 3K carbon fiber prepreg is The film layer is placed at the bottom;
[0026] 2. Mold entry: Put the cut prepreg (4 layers in total) directly into the molding mold that has been raised to a medium and low temperatu...
