ABSTRACT

Nowadays composite materials have become more popular for its wide range of applications and design flexibility. Since the fuel costs are increasing day to day, most of the automobile industries are conducting various experiments to develop composites having less densities and superior mechanical and tribological properties which are equally cost effective. In view of these types of composites most of the research is focused on improving mechanical and tribological properties aluminium alloys by adding with ceramic reinforcements.

Silicon carbide is a compound of silicon and carbon with chemical formula SiC. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.             Graphite is well known for its self-lubricating properties, which is a semi metal and an allotrope of carbon.

Research was done to improve the properties of aluminium using both graphite and SiC as reinforcements on various alloys. This work mainly focuses on the “Preparation and Analysis of Silicon Carbide & Graphite Particulate Reinforcements in Aluminium Matrix”.
