Evaluation of Mechanical Properties of Acacia-Jute-Sisal-Glassfibrereinforced Composite

Abstract

Now-a-days traditional materials are replacing the natural fibres in automobile components like dashboards, seat-backs and interior trims due to its properties like light weight, environment friendly, good stiffness and high strength to weight ratio . In the study three different continuous fibres, Acacia, Jute and Sisal were mixed in varying proportion with GFRP and epoxy resin on a determined ratio basis to get three different composite samples. These fibres were alkaline treated and moulded using compression moulding and hand lay-up technique. These samples were tested for their Tensile and Impact strengths to find the specimen with higher strength. Scanning Electron Microscope (SEM) test was also conducted to study the structure of all three specimens after tensile test. The study concludes that the sample ‘A’ which has maximum content of sisal has higher tensile strength than other two samples. Similarly impact test concludes that specimen ‘B’ and ‘C’ which has maximum content of Jute and Acacia has equal and higher strength.
