Mechanical and Micro Structural Properties of Aluminum Metal Matrix Composites (MMC) Reinforced with Coconut Shell Ash Particulates and Graphene

Abstract

This research article mainly focused on the fabrication of aluminum metal matrix composite reinforced with coconut shell ash particulates and graphene to enhance the mechanical and micro structural behaviour. The coconut shell ash particulates (CSA) and graphene are reinforced with 6061 aluminum alloy. The fabrication of aluminum metal matrix composites were prepared by adding various weight percentages of graphene and coconut shell ash particulates in aluminum alloy by using stir casting techniques with a restricted environment. The proper reinforcement on 6061 aluminum alloy materials play a very important role in enhancing its mechanical and micro structural properties. The results obtained reveal that the mechanical properties were improved by increasing the percentage on graphene and coconut shell ash particulates such properties are tensile strength, hardness and yield strength of 6061 aluminum alloy materials. The micro structural analysis reveals that the proper dispersion of graphene and coconut shell ash particulates in 6061 aluminum alloy materials. The enhanced mechanical properties were obtained by addition of 8wt% of coconut shell ash particulates and 0.8wt% of graphene.
