APPARATUS AND METHOD FOR MANUFACTURING MOLDED COMPOSITES USING A DISCRETE NETWORK OF TOOL SURFACE RESIN DISTRIBUTION GROOVES

A tool and its method of use, where a plurality of grooves (42, 44, 46, 48, 52, 54, 56, 58) are formed into the tool surface (22) of the tool. The grooves (42, 44, 46, 48, 52, 54, 56, 58) have different cross-section dimensions, different lengths, different configurations and/or different patterns t...

Zusammenfassung:	A tool and its method of use, where a plurality of grooves (42, 44, 46, 48, 52, 54, 56, 58) are formed into the tool surface (22) of the tool. The grooves (42, 44, 46, 48, 52, 54, 56, 58) have different cross-section dimensions, different lengths, different configurations and/or different patterns that function as tool surface resin distribution grooves (42, 44, 46, 48, 52, 54, 56, 58). The grooves (42, 44, 46, 48, 52, 54, 56, 58) distribute and deliver resin (70) supplied to the tool surface (22) throughout a dry fiber composite layup positioned on the tool surface (22) in resin infusion and resin transfer molding. The grooves (42, 44, 46, 48, 52, 54, 56, 58) are formed in the tool surface (22) extending to discrete areas on the tool surface (22) to direct a flow of liquid resin (70) to the discrete areas and infuse the dry fiber composite layup with the liquid resin (70) at those discrete areas of the tool surface (22).
