Beschreibung
Zusammenfassung:	A method of forming a natural fiber polymer composite article includes the steps of introducing into an extruder a polymer, a natural fiber and a supercritical fluid to form a natural fiber polymer mixture; extruding the natural fiber polymer mixture to form a well-dispersed natural fiber polymer composite; and injecting the natural fiber polymer composite into a mold to form an article. The supercritical fluid may be introduced after the polymer is introduced into the extruder or injection molding machine. The supercritical fluid may be introduced before or after the natural fiber is introduced into the extruder or injection molding machine.
