Zusammenfassung:	A tool and its method of use, where a plurality of grooves and/or a channel are formed into the tool surface of the tool. The grooves and/or channel distribute and deliver resin supplied to the tool surface throughout a dry fiber composite layup positioned on the tool surface in resin infusion and resin transfer molding. The grooves are formed in the tool surface extending to discrete areas on the tool surface to direct a flow of liquid resin to the discrete areas and infuse the dry fiber composite layup with the liquid resin at those discrete areas of the tool surface. When a channel is formed in the tool surface, a perforated plate extends over the channel to prevent fibers from the preform from being pulled from the preform and into the liquid resin flowing through the channel.
