Abstract
Abstract: The metal matrix composites are the wide family of materials aimed to enhancing of combined properties of reinforcements. The matrix utilized in the development of MMCs would be of any material, but preferably aiming for lighter structural materials and main objective is in the improvement of mechanical properties. Majority of the progress in the field of MMCs is closely connected to development in reinforcement for incorporation in MMCs. But the orientation of this research is towards the fabrication and testing of Al8011, Silicon Carbide and S-glass fibre are the combination to cast the hybrid MMCs. The metallic matrix used in the present investigation is Aluminium alloy. Metal matrix composites (MMCs) possess significantly improved properties including high specific strength; specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. There has been an increasing interest in composites containing low density and low-cost reinforcements. The present investigation has been focused on the using of silicon carbide and S-glass fibre as a reinforcement material in useful manner by dispersing in variable quantity into Aluminium-8011 to produce Hybrid MMCs by stir casting method and there by investigating its mechanical properties such as compressive strength and hardness of Al8011 metal matrix hybrid composites. Hence, it is proposed to form a new class of composite. Al8011 alloy reinforced with Silicon Carbide and S-glass to form MMCs using graphite crucible for casting. The MMC is obtained for different composition of SiC and S-glass fibre
