Abstract
In last few years, synthetic fibres are replaced by natural fibres for polymer composite due to their several benefits such as low density, environmental friendly, low cost and high specific mechanical performance.This work deals with the tensile, flexural and impact properties of the randomly oriented short sisal reinforced epoxy composite. The composites were prepared by hand lay-up method with various fibre length (5, 10, 15 and 20mm)but constant 30 weight percent of sisal fibre content. The result offered that tensile strength was not increased by reinforcing sisal but flexural strength was improved 25% by 15mm sisal fibreand large improvement was observed in impact properties by 20mm sisal fibre.
