Effects of SiC and carbon black on mechanical properties (tensile and flexural) of AA6082/SiC/CB metal matrix composites

The metal matrix composites (MMCs) consisting aluminium as matrix with variety of high strength reinforcements are extensively used in the manufacturing sectors due to its excellent mechanical properties, i.e., high strength and stiffness to weight ratio and corrosion resistance. The objective of the current research work is to investigate the effect of infusion of silicon carbide (SiC) and carbon black on mechanical properties of aluminium 6082/SiC/carbon black MMCs. The experimental research shows that the mechanical properties initially increases with increase in weight fraction of SiC particulates and weight fraction of carbon black in the matrix. Further infusion of SiC and carbon black particulates in the matrix material decreases the mechanical properties of the composite. On the other hand, for tensile strength and flexural strength, the influence of SiC has been found most significant than carbon black while for impact strength and hardness, carbon black influence is more significant than SiC.
