Abstract
A composite material molding method is provided for forming a composite material. The molding includes disposing carbon fiber in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When a threshold value of the pressure inside the cavity is set to a pressure that is lower than the clamping pressure and the resin is injected into the cavity while exerting an injection pressure that is equal to or greater than the clamping pressure on the resin until the pressure inside the cavity reaches the threshold value. Then, after the pressure inside the cavity has reached the threshold value, the inside of the cavity is suctioned.
