Abstract

An extruder capable of manufacturing fiber reinforced thermoplastics is disclosed. The extruder includes a barrel having two parallel bores of equal diameter, the centre distance between the two bores lesser than the diameter of the bore; and a shaft located within each bore, each shaft configured for rotation in the same direction; the shaft forming three zones within the barrel, the zones including a fiber entry zone configured for receiving fibers from an extruder inlet; a fiber incorporation zone configured for incorporation the fibers into a polymer mix, the fiber entry zone and fiber incorporation zone generate waves in the polymer mix; and a wave disruption zone capable of cutting of fibers to a desired length; wherein the fiber entry zone and the fiber incorporation zone includes at least one extruder wave element; and the wave disruption zone includes at least one wave disruption element
