ABSTRACT:
In a resin transfer molding process a preform is positioned in the cavity of a molding tool, the molding tool is closed and resin is introduced into the cavity. The preform is a resin transfer molding core with fiber reinforcement material affixed to its outer surface. Internal communication passages extend within the interior of the core, a first and a second internal communication passage each having an inlet opening and a discharge opening extending through the outer surface of the core. The molding tool has a first port and a second port. Fluid-tight communication is formed between the first port and the inlet opening of the first internal communication passage. Fluid-tight communication also is formed between the second port and the discharge opening of the second internal communication passage. Uncured resin is introduced into the cavity through the first port, to and through the inlet opening of the first internal communication passage. The cavity is vented through the discharge opening of the second internal communication passage, to and through the second port. The resin is cured to provide a fiber reinforced composite structure.
