 This study investigates the effects of fiber orientation and volume fraction on the mechanical and thermal properties of laminated jute-reinforced polyester composite, using hand-layup method to fabricate composite sheets with different orientations, 0°, 90°, 0°, 90°, 0°, 45°, 0°, 45° and 45°, 90°, 45°, and volume fractions of 20% and 30%. The study found that the mechanical strength, surface hardness and thermal conductivity of the composite sheets are increased with fiber volume fraction and varied with fiber orientation. The tensile strength, energy absorption and load bearing capacity are highest for 45°, 0°, 45° fiber orientation, while the flexural strength is highest for 0°, 90°, 0°, fiber orientation. The method and procedure of this research work can be used to fabricate moderate-sized jute-reinforced polyester composites with elevated in-plane strength in both longitudinal and lateral directions.
