Study on the mechanical behaviour of metal matrix composites (MMC)

Abstract

Combining two or more different base metals to create Metal Matrix Composites (MMC) results in the creation of new metals. Compared to their underlying material, composites offer superior characteristics. In today's industrial sectors, composites are notably important in the automobile sector. In order to create a novel composite using the stir casting process at standard ambient temperature, this work describes the reinforcing of the aluminium alloy with silicon carbide and copper in various ratios. Materials having metals as the base and separate, usually ceramic phases added as reinforcements to improve the characteristics are known as metal matrix composites. Whiskers and particles are examples of possible reinforcements. By changing the type of ingredients and their volume percent, the properties of metal matrix composites can be adjusted. They provide a superior mix of qualities that no monolithic material currently in use can match, and as a result, the aerospace and automotive industries are using them more frequently. MMCs' main advantage over other materials is their increased strength and hardness per unit weight. In this study, the tensile strength, hardness, and flexural strength of the composite were assessed. Sample 2 was discovered to have a maximum tensile strength of 175 MPa and a hardness of 71. The outcome demonstrates that the hybrid composite has superior mechanical characteristics.
