<P>PROBLEM TO BE SOLVED: To provide an RTM molding device that can achieve a high resin-impregnation velocity keeping the number of injection holes small when the resin is injected from a plurality points of the inner surface of a reinforcing fiber base material to achieve a short impregnation time, and to provide a molding method. <P>SOLUTION: There are provided: the RTM molding device, wherein a mold forming a cavity where the reinforcing fiber base material 7 is arranged includes a resin casting opening 9 open to face one surface of the reinforcing fiber base material 7, and wherein the resin is cast from the resin casting opening 9 to impregnate the reinforcing fiber base material with the resin, a cross-sectional surface of a resin passage at the tip end 21 of the resin casting opening 9 is enlarged, in view of the resin flow direction, compared with the cross-sectional surface of the resin passage just in front of the tip end; and the RTM molding method. <P>COPYRIGHT: (C)2013,JPO&INPIT |
