Experimental Investigation of the Mechanical and Tribological Properties of Jute Fiber Composites with Nano-Sized Al2O3 Ceramic Particle Reinforcement

Jute fiber, a sustainable and abundant material, has garnered attention as a potential reinforcement in composites. This study focuses on enhancing the jute fiber composite strength through the inclusion of Al2O3 nanoparticles at varying levels. Mechanical properties were rigorously examined to evaluate their suitability for high-stress applications. This research encompassed assessments of hardness, flexural strength, tensile strength, and impact resistance. The results indicate that the incorporation of Al2O3 nanoparticles significantly improves the composite mechanical properties. Increasing the Al2O3 content elevates hardness, enhancing resistance to indentation. Flexural strength tests highlight the increased stiffness and deformation resistance, rendering the composites suitable for structural use. Additionally, tensile tests reveal an enhanced load-bearing capacity under tension with higher Al2O3 percentages. An improved impact resistance confirms the durability and the ability to withstand sudden shocks. These findings present promising opportunities for utilizing Al2O3-reinforced jute fiber composites in industries requiring high-strength materials, such as the automotive, aerospace, construction, and sports equipment manufacturing industries, combining sustainability with enhanced mechanical properties.
