Influence of fiber parameters on tensile, flexural, and impact properties of nonwoven coir–polyester composites

The tensile, flexural, and impact properties of coir fiber/polyester composites were evaluated. The untreated green husk coir fibers with different proportion in length and content were used as reinforcements in polyester polymer-based matrices. The mathematical models of tensile, flexural, and impact properties were developed and optimized using statistical package to find the optimum fiber parameters for maximum mechanical properties. The results are shown that the fiber content in weight percentage is playing major role than the fiber length on the improvement of tensile, flexural, and impact strength properties.
