Abstract: In the last decades the composites have been widely used in the construction, automobile and aerospace industries. Among them, Natural fiber composites are emerging as low cost, lightweight and superior alternatives to synthetic fiber composites. This study related to the development of bio-degradable composites using Epoxy resin and Sisal/Jute fibers. The fibers are chemically treated at different percentages of NaOH i.e.,3%, 6% and 9%. Tensile and flexural strength of the composites were determined using UTM. The natural frequencies of the cantilever composite beam were determined analytically using Euler’s theory and numerically using Ansys 15.0. From the results, the results agree close to each other
