Influence of fibre weight fraction on the mechanical characteristics of the Caryota urens fiber reinforced polyester composite

The present study aims to assess the tensile properties of caryota urens fibre reinforced polyester composites. Composites were fabricated with different fiber weight fraction starting from 5% to 30% with 5% increment. The testing of composite material was done using ASTM standards. The results indicated that the tensile, impact and flexural properties of composite material were increased up to 25% fiber weight fraction after that it has been reduced due factors like fiber distribution had not uniform and adhesion between fiber and matrix had be reduced. Optimal weight fraction found from this study is 25%. The maximum tensile, impact and flexural strength obtained for the composites were 36.22 MPa, 62.21 MPa and 96.21J/m.
