<![CDATA[This research was conducted to obtain data on the effect of the volume fraction of palm fiber on the tensile strength, modulus of elasticity and impact strength of composites using a 157 Ortho-phthalic Unsaturated Polyester matrix with the hand lay-up method. The object of this research is a composite of palm fiber 2 mm with a variation of fiber volume fraction 15%, 25%, 30%. The highest tensile stress of fiber-reinforced composite 2 mm was found in the volume fraction of 25% with a value of 30.23 MPa. Meanwhile, the highest value of modulus of elasticity is in the volume fraction of 25%, which is 9063.33 MPa. And for the highest impact strength, fiber-reinforced composite 2 mm is found in the volume fraction of 30% with a value of 49.3 Kj/mm². Meanwhile, the lowest tensile strength is found in the volume fraction of 15% with a value of 15.9 MPa. And the lowest elastic modulus value is found in the 15% volume fraction with a value of 7046.66 MPa. And for the lowest impact strength value is in the 25% fraction with a value of 29.73 Kj/mm².]]>
