PROBLEM TO BE SOLVED: To provide a molding method and a molding device for a composite material where mold fastening pressure can be suppressed while reducing molding time.SOLUTION: Provided is a molding method for a composite material where a reinforcing base material is arranged at a cavity at the inside of a molding die capable of opening/closing, a resin is poured into the cavity in a state where mold fastening pressure is applied to the molding die, and the resin is cured to mold a composite material. After the closing of the molding die, the resin is poured into the cavity, when the pressure in the cavity attains the threshold value of the mold fastening pressure or lower, the inside of the cavity is evacuated, and the resin is expanded while exhausting the air (S201 to S207). In this way, the time of vacuum drawing is reduced, and, from the start of the injection of the resin to the completion of the injection thereof, the resin is injected in such a manner that the pressure in the cavity does not exceed the mold fastening pressure.SELECTED DRAWING: Figure 4 |
