Abstract

This paper exhibits the investigative work conducted on fracture toughness of aluminum–graphite metal matrix composites. The materials chosen for the study are aluminum 6061 as matrix and graphite particles as reinforcement. The said composite is prepared by using stir casting method. Al6061–graphite has been prepared for 3, 6, 9 and 12% of graphite particles. The fracture experiments of the Al6061–graphite metal matrix composites are carried out. Taguchi’s method is used to optimize the different parameters. The results of the experiments of Al6061–graphite MMC are compared with Al–SiCp MMC. From the results, it is cleared that the Al6061–graphite can be considered as a promising material for aerospace and automobile applications where high crack arrest capabilities and high strength with reduced weight are required.
