Abstract

Bio-composites are taking over the polymer based composites due to their multi fold advantages. In this work, the natural fibre (jute-hemp) hybrid composite was prepared by traditional hand-lay-up method. The hardness, tensile and flexural properties of the composite specimen was evaluated in order to study the effect of fibres and fibre orientations using standard procedures. A significant improvement in hardness (114RHN), tensile (79.13mpa) and flexural (120.06mpa) properties were observed with fibre orientation of 900 compare to 300 & 450 orientations. Specific gravity test were conducted by using ASTM D792 standard at the temperature of 230c. The specific gravity was found to increase for 900 orientation of the fibre in the composite. It is also observed that the polyester based hybrid composite exhibits higher values of mechanical properties compared to epoxy based hybrid composites.
