<P>PROBLEM TO BE SOLVED: To provide an RTM method which not only improves the quality of a design surface of a molded object but also molds a thick-walled structure with excellent resin impregnation properties. <P>SOLUTION: In the RTM method, the resin flow resistance of a second resin diffusing medium arranged on the second surface of a reinforcing fiber base material is made lower than that of the first resin diffusing medium arranged on the first surface of the reinforcing fiber base material in a mold and the reinforcing fiber base material is impregnated with a resin by sucking the resin through the second resin diffusing medium while injecting the resin into the first resin diffusion medium. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
