This study examines the tensile properties of cellulose microfiber (CMF) / maleic acid polypropylene (MAPP) /polypropylene (PP) composites. To form interface between CMF and PP, surface of CMF was coated with a hydrophobizing agent (HA). HA helps CMF dispersion in PP. MAPP that having interface modification effect added in PP to improve CMF dispersion. CMF have a length of 10 μm or more, and diameters of 1 μm or more. Using twin-screw extruder operating at 200rpm and 200°C, CMF/MAPP/PP composites were prepared by melt-kneading. Tensile tests were performed to examine the tensile properties of CMF/MAPP/PP composites. The maximum stress of the composites improved with the increase of CMF content, but the failure strain decreased significantly. The MAPP content had an effect on the tensile properties of 5wt%CMF/MAPP/PP composites.
