This research investigates the mechanical characteristics of bio-composites reinforced using jute and sisal fibers. Natural fibers have emerged as promising alternatives because of their low density, renewability, biodegradability and approving mechanical properties. The research involvedfabricating bio-composite plates using the hand lay-up method with varying orientations of jute and sisal fibers. The mechanical parameters, including tensile strength, impact strength, and flexural strength, were rigorously assessed and compared across various fiber orientations. The results revealed that composites with a 90-degree fiber orientation expressed loftier tensile andflexural strengths compared to those with a 45-degree orientation. The 90-degree oriented composite exhibited a tensile strength of 31.84 MPa and a flexural strength of 88.2 MPa, while the 45-degree oriented composite showed a tensile strength of26.21 MPa and a flexural strength of 43.7 MPa. Contrarily, the 45-degree oriented composite displayed a significantly higher impact strength of 24.6 kJ/m2 compared to 11.59 kJ/m2 in the 90-degree oriented composite. The results indicate that the orientation of fibers is essential in influencing the mechanical performance of composites reinforced with natural fibers. The 90-degree orientation is recommended for applications requiring higher tensile and flexural strengths, whereas the 45-degree orientation offers better impact resistance. These bio-composites holds a great potential for applications in the aerospace, automotive and construction industries, where material sustainability, weight reduction and mechanical efficiency are critical. The study underscores the viability of using natural fibers as ecofriendly augmented materials in composite structures, promoting a shift towards greener alternatives in material engineering.
