Experimental Investigations to Improve Mechanical Properties of Sisal Reinforced E-Glass Fiber

The composite materials are replacing the traditional materials, because of its superior properties such as high tensile strength, low thermal expansion, high strength to weight ratio. The developments of new materials are on the anvil and are growing day by day. Natural fiber composites such as sisal polymer composites became more attractive due to their high specific strength, lightweight and biodegradability. Mixing of natural fiber with E-glass-Fiber Reinforced Polymers is finding increased applications. In this study, sisal glass fiber reinforced epoxy composites is developed and their mechanical properties such as tensile strength, compression strength and Hardness tests are evaluated. The interfacial properties, internal cracks and internal structure of the fractured surfaces are evaluated by using Travelling Microscope. The results indicated that the incorporation of sisal fiber with E-glass can improve the properties and used as an alternate material for glass fiber reinforced polymer composites.
