Bagasse fiber composites were fabricated to improve the formability and quality. To archive this objective, MFI, surface roughness and odor were studied. The MFI in the composites was increased by using high-flow polypropylene to improve the formability. The surface roughness was most smooth when the injection conditions were in range of high injection speed and high temperature in mould. This was due to the skin layer formed in the composites. The odors in the composites were found as cyclopentenelones and guaiacols by gas chromatography analysis. These odors were caused by thermal pyrolysis of a hemicellulose with water. To avoid the odors, the effect of the thermal drying were investigated.
