Comparative Analysis of Mechanical Properties in Hybrid Composites Using Neem and Indian almond Fiber

This study examines the mechanical properties and microstructural aspects of epoxy composites that have been reinforced with neem and Indian almond fibers. These fibers were first treated with a 5% NaOH solution by immersing them in it, leading to increasing surface roughness and improved bonding with the epoxy resin. Composite samples were made using the hand lay-up method, and a weight ratio utilized was 70:30 for resin-to-fiber. The tensile, flexural, impact, and wear strengths were analyzed in the testing profile of the composites. The composites were analyzed using FTIR spectroscopy and microstructural investigations to get insight into the interactions between the fibers and matrix, as well as the shape of the materials. Results showed that the tensile and flexural strengths had been improved significantly in comparison to the original epoxy material. It is, therefore, the results emanating from impact and wear tests, which rescue the endurance of these composites for application in the automobile and construction industries. The results indicate that the inclusion of natural fibers in polymer matrices not only improves mechanical performance but also promotes environmental sustainability.
