Hybrid composites were fabricated using jute fibers oriented at 45°, 60°, and 90°, combined with glass fibers in an epoxy matrix. Mechanical testing included hardness and impact tests to understand the influence of fiber orientation on the overall properties of the composites. The results demonstrated a significant correlation between fiber orientation and the mechanical behavior of the composites. The 60° jute fiber orientation exhibited superior impact strength, attributed to its ability to absorb and dissipate energy more effectively under dynamic loading conditions. On the other hand, the 90° orientation resulted in higher hardness values, indicating better resistance to localized deformation. The 45° orientation showed balanced performance but did not surpass the other configurations in either hardness or impact strength. This study highlights the importance of fiber orientation in designing hybrid composites to achieve desired mechanical properties. By optimizing orientation, it is possible to tailor the composite for specific applications, such as automotive, aerospace, and structural components, where lightweight materials with enhanced strength and durability are crucial. These findings provide valuable insights for future development of sustainable, high performance composite materials.

Hybrid laminates were fabricated by combining natural jute fibers with synthetic glass fibers in an epoxy resin matrix, with the jute fibers oriented at 45°, 60°, and 90°. Mechanical evaluations were carried out through hardness and impact strength tests to assess the influence of fiber alignment on the composite’s response to static and dynamic loading. The experimental results revealed that fiber orientation plays a critical role in governing the overall mechanical performance of the composites. Among the tested configurations, the 60° jute fiber orientation achieved the highest impact resistance, attributed to enhanced energy absorption and dispersion capabilities. Conversely, the 90° orientation produced superior hardness values, indicating better localized load resistance. The 45° orientation demonstrated moderate performance, balancing between hardness and impact properties but not exceeding the other two orientations. These outcomes emphasize the significance of optimizing fiber orientation in hybrid composites to tailor material properties for diverse engineering applications. The findings contribute to the development of sustainable and high-performance composite materials, suitable for automotive, aerospace, and structural components where lightweight design and mechanical efficiency are essential.

Hybrid samples were fabricated with jute fibers arranged at 45°, 60°, and 90°, in combination with glass fibers within the epoxy matrix. The composites were evaluated through impact and hardness tests to determine how orientation affects their overall performance.The experimental findings revealed a clear dependence of mechanical properties on fiber orientation. Composites with a 45° jute fiber alignment displayed the highest impact,hardness and bending strength, owing to their enhanced energy absorption capacity during dynamic loading. Meanwhile, the 60° orientation resulted in superior hardness, indicating stronger resistance against localized surface deformation. The 90° orientation showed balanced performance but did not surpass the other configurations in either hardness,impact or bending strength.These results emphasize the importance of selecting appropriate fiber orientations to tailor composites for specific applications. Optimized orientation can significantly enhance the design of lightweight structural materials, making them suitable for use in automotive, aerospace, and construction industries. Overall, the study contributes useful insights toward the development of sustainable and high-performance hybrid composites Mon, 11 Aug 2025 00:00:00 GMT http://suspace.su.edu.bd/handle/123456789/2532 2025-08-11T00:00:00Z http://suspace.su.edu.bd/handle/123456789/2531 INVESTIGATION OF MECHANICAL PROPERTIES OF HARDENER RESIN COMPOSITES REINFORCED WITH JUTE AND GLASS FIBERS Alamin, Mia This thesis investigates the mechanical properties of epoxy resin composites reinforced with jute and glass fibers, aiming to develop eco-friendly materials with industrial applicability.
