Natural fiber reinforced composites are potentially useful materials with respect to environmental concerns. The geometry or the forms of the reinforcement in a composite greatly influences the mechanical properties of the composite. The common forms of jute reinforcement are chopped fiber, sliver, yarn, woven fabric, knitted fabric and nonwoven mat. In the present study, Composites were fabricated by incorporating jute sliver in unsaturated polyester (UPE) resin. Jute sliver (JS) reinforced unsaturated polyester (UPE) resin composites [JS/UPE] were prepared by compression molding technique. Jute fiber content in the composites were varied from 10-60% by weight and mechanical properties were measured in both longitudinal (along fiber/sliver axis) and transverse direction. Composite comprised of 50% jute sliver showed the best mechanical properties. At optimized fiber content (5o% fiber by weight) the value TS, TM, BS, BM and IS of jute sliver reinforced UPE composite, JS/UPE, were found to 140.25 MPa, 6.75GPa, 160.5. MPa, 13.7 GPa and 27.2 KJ/m2 in longitudinal direction and 18.32 MPa, 0.8 GPa, 44.1 MPa, 1.3 GPa and 5.2 KJ/m2 in transverse direction respectively.
