The use of synthetic fibers harms the environment. Therefore, this study uses natural fibers, to determine the effect of fiber angle orientation on composite jute-epoxy fibers on bending and impact strength. The material used is jute and epoxy fibers. Percentage of gunny volume: epoxy is 40%: 60%. The orientation used is 0°, 45° and 90° with variations 0° + 0°, 0° + 45°, 0° + 90° and 45° + 90°. Composites are made using the pressing method. The standards used for bending and impact tests are ASTM D 790 and ASTM D 6110. The average value of bending strength is obtained and the modulus of elasticity of bending is highest at 100% epoxy and variations of 45° + 90° are 53.58 MPa and 1.889 GPa. The highest average impact strength of 100% epoxy is 0.0127 Joule/mm2. The use of fiber orientation does not increase the strength of the impact of jute-epoxy fiber composites. © 2023 Author(s).
