Mechanical Characterization of Palmyra- and S Glass Fibre-Reinforced Hybrid Polymer Composites

The need of composite materials is intensive in last few decades as the reinforced polymer composites can be processed easily in many constraints and there are many advantages of using Palmyra fibre. Here, the Palmyra fibre is combined with glass fibre as matrix epoxy resin is taken to improve the properties. In the present work, Palmyra fibre is reinforced with glass fibre and epoxy resin in different ratios by hand lay-up method and is processed and different tests are conducted. This includes evaluation of tensile strength, flexural strength, compression strength and impact strength has been studied and discussed. The characterization of composites reveals that different ratios of Palmyra palm and glass fibre are having significant effect on the mechanical properties of composites. Tensile strength, tensile modulus, flexural strength, flexural modulus, compression strength, compression modulus and impact strength are found to be improved for all treated samples when compared to untreated samples. Flexural and tensile properties are improved due to removal of dust particles on surface of fibre; hence, cell walls of fibre are opened to wet matrix interface
