Prediction of mechanical properties of hybrid aluminium composites

Abstract

The modern manufacturing industry needs highly characterized materials for a variety of applications, which leads the material researchers were focuses on hybridization in the aluminium metal matrix with various reinforcements. In this research investigates the mechanical properties of aluminium alloy Al 6061 with the reinforcement of silicon carbide and eggshell particles in various proportionalities. The stir-casting method is used to prepare the Al 6061 based hybrid aluminium composite material by varying the weight percentage of both silicon carbide and eggshell particles; the reinforcement material of eggshell increases the hardness of the material with least expensive. The Al 6061 based hybrid aluminium metal matrix test specimens were fabricated as per ASTM standards in the water jet machining process. The Al 6061 based hybrid aluminium metal matrix composite was characterized by various mechanical tests such as tensile load, tensile strength, percentage of elongation, yield load, yield strength, compressive strength, impact strength, impact energy and Rockwell hardness. In the tests reveals that performance of the pure aluminium alloy Al 6061 considerably lower value in impact tests. The 8 wt% of silicon carbide with 4 wt% eggshell particles reinforce hybrid aluminium metal matrix composite is performed very well in the tensile, compressive and hardness tests.
