Investigation of Mechanical Characterization on Al-7075 Reinforced with Silicon Carbide and Graphite

Abstract

Composite materials defined as two or more chemically different constituents that are combined microscopically to yield a useful material. The properties of new material are significantly different than that of constituents. This can be classified into three different types, which are metal matrix composite, polymer matrix composite, ceramic matrix composite. In this journal we work is on metal matrix composite. Aluminium Metal Matrix Composites (AMMC) have good mechanical properties which has various applications like automobile, military industries, aerospace and others due to light weight, thermal properties, stiffness, high mechanical strength corrosion resistance. The present work deals with the preparation and mechanical characterization of Aluminium 7075 metal matrix reinforced with silicon carbide and graphite. Composition can be made 3% graphite and silicon carbide variations like 2%, 4%, and 6% with Aluminium. To prepare this material and test mechanical characterization like tensile strength, compressive strength and hardness
