Abstract

A method of manufacturing a workpiece includes heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven. A second fiber reinforced thermoplastic material is heated in an extruder. The second fiber reinforced thermoplastic material is extruded from the extruder, within the oven, to form an extrudate. The extrudate is positioned on the pre-formed blank of the first fiber reinforced thermoplastic material, within the oven, to form a composite blank. The extrudate may be formed into a shape before being positioned onto the pre-formed blank, after being positioned onto the pre-formed blank. The composite blank may then be transferred to a final shaping station.
