ABSTRACT:
The invention provides a preform for a resin transfer molding process and a preform core for same. The invention further provides a resin transfer molding process employing such preform. A surface portion of the core having a concavity therein, the core comprises a flexible web secured to its surface forming a convexity over such concavity. The convexity formed by the web is deformable into the concavity during the resin transfer molding operation, but prior to the molding operation is sufficiently firm to support, without substantial deformation, oriented continuous fibers applied under tension onto the surface of the core.
