    A composite material is a ‘material system’ composed of a combination of two or more micro or macro constituents that differ in form, chemical composition and which are essentially insoluble in each other. Metal matrix composites are become a highly important material in automotive industries due to its light weight and high strength properties. In this investigation, the composites were fabricated using liquid metallurgy route i.e stir casting method. Ceramic particles along with solid lubricating materials were incorporated into aluminium alloy matrix to accomplish reduction in both wear resistance and coefficient of friction. The Al 7075/SiC/graphite hybrid composite was prepared with 3 wt.% graphite particles addition and 3,6, and 9 wt.% of SiC. The study of wear characteristics on Al 7075/SiC/Graphite hybrid composite were carried out. The wear properties of the hybrid composites containing graphite exhibited the superior wear-resistance properties.
