Abstract:For a study of wood (cellulose) polypropylene composite with high filler content, the effects of resin content and cellulose fiber length on the fluidity of compound and physical properties of mold products were evaluated and discussed. Results are summarized as follows: 1. In the compounding process, void induced by cellulose fiber had influence on the discharge rate, 2. Results of viscoelasiticity and wet strength indicated the effect of tangle of fiber is dependent on resin content and cellulose fiber length. 3. The compound of 300ƒÊm fiber length and 20% resin content showed thixotoropic flow and improved the molding characteristics. This paper would contribute for manufacture of high performance composites with high content of cellulose fiber. Key Words:Cellulose-plastic-composite, Tangle of fiber, Viscoelasitc, MFR
