ABSTRACT:
A fiber-reinforced thermoplastic composition for producing composite structural members and a method for making same is provided. The composition is made by combining a thermoplastic resin with pre-treated high moisture cellulosic materials, such as discarded newspaper, having lignin contained therein. Moisture treatment of the cellulosic materials exhibit improvements over composites using dry cellulosic materials. The composite composition may then be extruded or compression molded into various articles of manufacture.
