Natural fiber reinforced composite materials were manufactured by reinforcing Grewia Serrulata with unsaturated polyester matrix material. To improve the adhesion between fiber/matrix interphase; fibers were treated with Silane, Acetylation and Potassium Permanganate solutions. Partially biodegradable composite materials were prepared using hand lay-up technique. Toughness and hardness of the materials were investigated according to ASTM standards. Acetylation and Silane treatment of Grewia Serrulata improved the compatibility between the matrix and the fibers and resulted in significant enhancement of hardness and impact strength.
