Beschreibung
Zusammenfassung:	An RTM molding method comprising disposing a reinforcing fiber substrate (9,23) in a cavity of a mold (1,20) consisting of a plurality of dies (2,4,21,22), clamping the mold, and thereafter injecting resin to complete molding, characterized in that divided areas with respect to the surface direction of the reinforcing fiber substrate are assumed, each divided area is one in which injected resin expands over the entire surface in the area and can be substantially uniformly impregnated in the thickness direction of the substrate, and resin introducing paths are formed for respective assumed divided areas for introducing the injected resin into the respective divided areas; and a random mat layer is placed in the reinforcing fiber substrate.
