Abstract
Abstract Aluminium and its alloys (AA) offers greater potential for weight reduction in automotive, ship building, and aerospace industries. But the main problem in aluminium alloy is less endurance to high temperatures and less wear resistance characteristics. In order to overcome these problems, researchers have been reinforcing ceramic particles with AA. In this study SiC and Graphite (Gr) with aerospace grade aluminium alloys and its recent development clearly reviewed. The effects of SiC and Gr on the microstructures, mechanical and wear properties of the composites were studied. From the literature, hardness and tensile strength of the composite increases with increasing SiC content and decreases with increasing graphite. The damping capacity of MMCs dependent on graphite volume fraction and relatively independent on SiC particulates volume fraction. The wear resistance increases with addition of SiC and Gr when compared to the base alloy.
