    Abstract: A twin screw extruder compounds a thermoplastic resin material with a randomly oriented fiber reinforcing material to produce a molten fiber reinforced thermoplastic extrusion from a die. The extrusion is cut into preforms which are immediately inserted into a compression mold for making parts. A unidirectionally oriented fiber reinforcing material can be added in the die. The fibers are monofilaments which are debundled and heated before entering either the extruder or the die.
