Abstract: Hybrid composites are those composites which have a combination of two or more reinforcements in a single matrix. In this study, Hybrid Aluminum Metal Matrix Composites were fabricated by using Stir Casting technique. Hybrid composites with three reinforcements such as Aluminum oxide(Al2O3), Silicon Carbide (SiC) and Boron Carbide (B4C) in different proportions are considered and Aluminum alloy 6061-T6 (Al-6061) as base alloy matrix. Later, the cast aluminum metal matrix composites were machined as per ASTM standards with required dimensions. Mechanical tests such as tensile, flexural, Charpy impact, Brinell Hardness tests were conducted on the composites fabricated inorder to evaluate effect of reinforcements. Morphological study of the composites is carried out by using Scanning electron microscope (SEM). The test results were studied and analyzed.
