Injection molded vetiver-polypropylene (PP) composites at various ratios of vetiver content and vetiver length were prepared. When compared to PP, vetiver-PP composites exhibited higher tensile strength and Young's modulus but lower elongation at break and impact strength. An increase in vetiver content led to an increase in viscosity, heat distortion temperature, crystallization temperature, and Young's modulus of the composites. On the other hand, the decomposition temperature, tensile strength, elongation at break, and impact strength decreased with increasing vetiver content. The chemical treatment of the vetiver grass improved the mechanical properties of the composites. (c) 2006 Elsevier Ltd. All rights reserved.
