Abstract

A method and apparatus of molding a hollow fan blade is disclosed wherein a fiberglass preform is used to support the upper layers of fiberglass cloth within a mold. As resin is injected into the mold, both the fiberglass cloth and the fiberglass preform become impregnated thereby bonding the two together into a single unit during the molding operation during which heat and pressure is applied.
