Abstract
A method of molding a hollow fan blade in which a preform (preferably constructed of glass fibers) is used to support the upper multiple layers of to-be-impregnated cloth within a mold. As resin is injected into the mold, the cloth and the preform become impregnated thereby bonding the two together to form a single unit during the molding operation.
