In today’s world low weight and high efficiency with no compromise to mechanical properties is the main area of attention of researcher’s. In this arena design of composite materials is emerging as the challenging field of research. With the design of Metal Matrix Composites (MMC’s) one can achieve tailor made properties, which otherwise are impossible to achieve out of single material. In this book, liquid metallurgy technique has been suggested to develop Aluminum-Silicon Carbide (Al-SiC) Metal Matrix Composite (MMC’s). Then emphasis has been made to characterize the tribological properties of the MMC’s with its focused application in the automobile sector.
