    摘要: A process is provided for forming a fiber-reinforced resin structure having an opening therein by vacuum bag forming. A resin infusion port is disposed adjacent a mold surface. The resin infusion port has a resin inlet and at least one resin outlet. A fiber-reinforced ply is distributed adjacent the mold surface about the resin infusion port. A flexible covering is placed over the fiber-reinforced ply and the mold surface to form a chamber therebetween. The chamber is evacuated. Resin is dispensed into the resin infusion port through the resin inlet. The resin is infused into the ply by dispensing resin into the chamber from the resin infusion port through the resin outlet. The resin is cured within the resin infusion port and within the chamber to form a cured resin structure which is subsequently removed from the mold surface. An opening is formed in the resin structure by removing the resin infusion port and a portion of the resin structure adjacent the resin infusion port.

    摘要: In accordance with the present invention, there is provided a process for optimizing resin distribution during VARTM fabrication of a fiber-reinforced resin structure having a core body having a core upper surface extending between first and second edges, and at least one ply disposed upon the core upper surface. Longitudinal resin distribution grooves acre formed along the core upper surface substantially parallel to the longitudinal resin flow axis. Lateral resin distribution grooves are formed along the core upper surface. A vacuum is drawn between the resin infusion and the vacuum application ports. Resin is dispensed at the resin infusion port. The longitudinal and lateral resin distribution grooves are formed to wet the fiber-reinforced ply at substantially equal ply resin wetting rates in directions along the longitudinal resin flow axis and perpendicular thereto.

    摘要: In accordance with the present invention, there is provided a process for forming a fiber-reinforced resin structure against a mold surface by vacuum bag forming. The process includes grooving the mold surface to form resin distribution conduits therein. A fiber-reinforced ply is distributed adjacent the mold surface. A flexible covering is placed over the fiber-reinforced ply and the mold surface to form a chamber therebetween. The chamber is evacuated. Resin is dispensed into the evacuated chamber such that the resin enters the resin distribution conduits and is thereby distributed about the ply.
