Beschreibung
Zusammenfassung:	A method of RTM molding characterized in that a reinforcing fiber substrate (4) is placed in a mold (1), a resin distribution medium (5) exhibiting a resin flow resistance lower than a resin flow resistance of said reinforcing fiber substrate is placed on a surface of said reinforcing fiber substrate opposite to said mold, a degasification medium (54) comprising a gas permeation film (50) and a gas permeable substrate (51) is provided between said reinforcing fiber substrate and said mold, a resin (10) is injected into said mold through said resin distribution medium after a pressure in said mold is reduced by evacuation, and said resin injected is impregnated into said reinforcing fiber substrate by evacuating said resin injected from a degasification space formed between said gas permeation film and said mold.
