Natural fibers came into exposure from the research community like never before in the history, due to the number of advantages over traditional synthetic fibers, like low cost, low density, high specific strength and modulus, easy availability, renewability and much lower energy requirement for processing. This research deals about the mechanical properties of composites like Jute and Banana as reinforcing materials in epoxy resin based polymer matrix, for making partially green biodegradable material composite via hand lay-up technique. Jute is a rain fed crop, the fibers are extracted by retting. Banana fiber can be obtained easily from the plants, which are rendered as waste after the fruits have ripened. These fibers are exposed to NaOH treatment before reinforcement. The reinforcing of the resin with Jute and Banana fiber accomplished in four different orientations: 0°, 15°, 30° and 45° with reference to horizontal side of the sheet by employing optimized resin. Mechanical properties (Tensile, Impact) of both Jute fiber composites and Banana fiber composites were investigated as a function of fiber orientation. Results showed that the composite properties are strongly influenced by test direction and fabric characteristics. Comparatively, Composites tested along the Jute fabric 0° orientation obtained best overall mechanical properties.
