In this research, the composite material was prepared from untreated and treated corn cob powder by acetylation process and the physical and mechanical properties have been studied. Cellulose is extracted using the Kürchner-Hoffer method and then acetylated. Untreated corn cob powder and Acetylated corn cob powder were mixed with unsaturated polyester resin in different concentrations (0, 1, 2, and 3 wt. %). The Mechanical and the physical test results showed that there is an enhanced in mechanical properties (Tensile, Impact, Hardness, and Bending) with the treatment (Acetylation) by increasing treated corn cob powder mass fraction (1, 2, and 3wt. %) respectively.
