A method for compression molding a resin-impregnated preform to fabricate an impact-resistance, fiber-reinforced composite fan blade for use in a high bypass turbofan engine. The method is compatible with the use of high viscosity resin systems that contribute greater impact resistance to the fan blade, but whose flow through the fan blade during molding would cause unacceptable movement of the reinforcing fibers. The method entails restricting the flow of the resin system within the preform through selective placement of a resin-impervious material on certain surfaces of the preform, so as to prevent resin loss and fiber movement during the compression molding operation.
