Effect of Fibre Orientation on Specific Gravity, Hardness, Flexural Strength and Tensile Properties of Jute/Hemp Hybrid Laminate Composite

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.
