Influence of fiber surface modifications on the mechanical behavior of Vetiveria zizanioides reinforced polymer composites

ABSTRACT

The natural fiber is pretreated with chemicals namely, alkali, peroxide, and benzoyl chloride. Composites are prepared using chemically treated fibers as reinforcements and mechanical characteristics are tested. The results confirmed that, benzoylation improved the tensile, compressive, and impact strengths of the composite by 113%, 56.78%, and 95%, respectively. Peroxide treatment has improved the flexural strength by 56.13% and improved the elongation of the composite during tension, flexure, and compression tests. The surface morphology showed minimal defects in the benzoylated composite and hence, benzoylation is suggested for the best overall behavior and peroxidation for enhanced bending and elongation.
