Natural fiber composites have attracted significant response in the field of structural mechanics for more than a decade since they hold varieties of desirable advantages. They exhibit comparably minimal amount of pollution effect to the environment. Because of being with great strength to weight ratio, different kind of research works with different kind of natural fibers have been made by the researchers for many specific application areas. In the proposed work, sisal and banana natural fibers have been hybridized with the distributing medium of epoxy resin under three different combinations to form the composite structures. Mechanical strength analyses were performed on the proposed composite specimens such as tensile strength and flexural strength tests. Numerical analyses have also been made for ensuring the experimental results. Grey Relational Analysis has been performed with the results of the two mechanical strength tests to identify the best combination among the three which yields good mechanical property under all tensile and flexural loading conditions.Natural fiber composites have attracted significant response in the field of structural mechanics for more than a decade since they hold varieties of desirable advantages.
