Abstract:
The effect of fiber volume fraction on the tensile properties of rice husk reinforced polyester composites was studied. Tensile properties was evaluated by using different volume fraction of rice husk fibers, (5%, 10%, 15% and 20%). Composites were produced by using a hand-layout technique. Untreated rice husks were mixed with unsaturated polyester and pour into the mould. Analysis of variance (ANOVA) was conducted at the end of the experiment by using one way ANOVA. The results showed the decreased tensile strength and tensile modulus when increasing the fiber volume fraction, which indicates that ineffective stress transfer between the fiber and matrix.
