Abstract: In this research, the alkaline treated and untreated sugarcane bagasse was used as reinforcement with unsaturated polyester to make composites. The composites were made with 0 to 20 weight percentage of fibers using compression molding. Acoustical, dielectrical and mechanical properties of the composites were studied according to the American Society for Testing Materials (ASTM) standards. The result shows that the composites with higher sugarcane bagasse loading show higher acoustical and dielectrical properties. The composites tensile strength increased up to 10wt% of fiber loading and then starts decreasing eventually. Tensile strength and sound absorption coefficients of alkali treated fiber composites shown slightly better results than untreated fiber composites. The dielectric constant of treated fiber composites were lower compared with untreated fiber composites.
