Abstract :

The present work is on the mechanical study of hybrid composites made out of s-glass fiber being combined with carbon fiber as synthetic reinforcements reinforced with thermoset polymer matrix; namely epoxy by hand layup technique of required laminate thickness suitable for testing as per ASTM standards. The mechanical behavior of the hybrid material formed with the differently stacked fiber layers at required proportion were maintained for the tests. The physical and mechanical properties such as density, tensile, impact, flexural and hardness properties of the hybrids composites were determined after being subjected to various mechanical loads under controlled standard condition. The test results, reveals that the combination of 4K-2S-4 K-E-HC hybrid in the material system has higher hardness, density, tensile, and impact properties, but the material configuration of 3K-2S-3K-2S-E-HC exhibited good flexural strength. S-glass fiber being employed in the hybrid has been quite increased the mechanical abilities. SEM pictures taken show the morphology of failed sample under tensile loading indicating fiber breakage, fiber pull-outs and matrix failure across the fiber interaction.
