The use of natural fibres like borassus flabellifer fiber, flax, sisal, jute, kenaf, etc. as replacement to manmade fibres in fibre-reinforced composites have increased now a days due to advantages like low density, low cost and biodegradability. But the natural fibres have poor compatibility with the matrix and they have relatively high moisture sorption. In this research, the standard test method of ASTM D638M-89is used to prepare specimens as per the dimensions for testing tensile properties of fiber-resin composites. The test specimen has a constant cross section with tabs bonded at the ends. The specimens were incorporated with borassus flabellifer fiber. Five identical specimens were prepared for each weight by varying fiber content in grams i.e. 0.5, 1.0, 1.5, 2.0, 2.5. Tensile strength of fabricated composites increases with increase in weight of fiber. The tensile properties of pure polyesters are also determined experimentally. The tensile strength of pure polyester is 35.2 N/mmÂ².The tensile strength of a fibered composite is 64.51 N/mm2 (for maximum loading fiber that is at 2.5 grams).
