Abstract

Abstract: Natural fibre reinforced polymer composites have been proved to be competitor for glass fibre reinforced polymer composite due to their acceptable strength and low cost. The epoxy based sisal composites are prepared by Hand lay-up technique using short sisal fibres of sizes (5, 10, 15 and 20 mm) keeping constant 30 wt.% of total fibres content. The dynamic mechanical properties of short sisal fibre reinforced epoxy composite is determined in terms of storage modulus ( E ′ ), loss modulus ( E ′ ′ ) and damping ( Tan δ ) at different frequencies such as 1, 2 and 5 Hz. The results indicate that storage modulus and loss modulus are found to be high for the composite having 15 mm length of fibres .
