A Study on Mechanical Properties of Silicon Carbide, E-Glass and Red Mud Reinforced Aluminium (LM25) Composite

Abstract

In this paper results of an experimental investigation of the mechanical properties of SiC, E-Glass and Red mud reinforced aluminium alloy (LM25) composites samples, processed by stir casting route are reported and analyzed. Four sets of composites with constant weight fraction of two reinforcements and varying one reinforcement (3 Sets) and a base metal specimen. The main mechanical properties studied were the tensile strength, ductility impact strength &hardness. Unreinforced LM25 samples were also tested for the same properties. In our study we varied the reinforcing material in smaller quantity to avoid the mixing problem. And from the results what we got shows the addition of reinforcing materials like Red mud, E-Glass and SiC improves tensile strength, Impact strength and reduces % Elongation. But addition of E-Glass minimizes the hardness.
