METHOD OF MAKING POLYMER/NATURAL FIBER COMPOSITE PELLET AND/OR A COUPLING AGENT/NATURAL FIBER PELLET AND THE PELLET MADE BY THE METHOD

摘要

A method of making a polymer/natural fiber composite pellet and/or a coupling agent/natural fiber pellet and the pellet made by the method. The pellet is intended to be used in molded structural composites comprising thermoplastic polymers and fibers. It is produced by carding or combing the natural fibers and to form a sliver or roving therefrom, which is combined with the polymer and/or coupling agent in a melted or dissolved state. The fibers may either be dispersed in the polymer through an extrusion process or be present as an inner core surrounded by an outer sheath of polymer and/or coupling agent.
