The incorporation of nanolayered silicate has been considered in recent years for improving the properties of thermoplastic composite. In this study a composite of polypropylene (PP) and bagasse fiber (BF), with different concentrations of nanoclay and maleic anhydride (MA) as compatibilizer, were fabricated by injection molding. Then physical and mechanical properties of the composites were tested according to ASTM standards. The results indicated that tensile modulus and flexural strength increased with an increase in clay loading; however, impact strength and water absorption decreased with an increase in nanolayered silicates. The degree of nanoclay dispersion in PP/BF composite was characterized by X-ray diffraction (XRD) method. The morphological study showed that the intercalation morphology in nanocomposite samples and d-spacing of layers increased with an increase in clay content. The effect of compatibilizer was positive in terms of enhancing the properties of composites. The maximum physical and mechanical properties of samples were achieved with 3% nanolayered silicates and 2% coupling agent. Key words: Bagasse, compatibilizer, injection molding, nanolayered silicates, polypropylene Introduction The global wood plastic composites (WPC) market has been experiencing double digit growth since 2003, with a similar trends projected up to 2010. Current product lines include lumber, decking and railing, window profiles, wall studs, door frames, furniture, pallets, fencing, .
