Abstract
The mechanical characteristics of graphene and coconut shell ash (CSA) particles added to aluminium 6061 metal matrix composites (MMC) are examined in this work. In the process of fabricating composites, stir casting is used, with CSA fluctuations ranging from 0 to 8% and a constant graphene content of 0.6%. Scanning electron microscopy (SEM) micrographs were obtained to provide detailed insights into the microstructure of different aluminium matrix composites (AMCs) reinforced with graphene nanoparticles (0.6% C) and varying percentages of coconut shell ash (CSA) at different concentrations (2%, 4%, 6%, and 8% CSA). The hardness results show a consistent increase with higher coconut shell ash (CSA) content in aluminium (Al6061) composites, while keeping the nanographene content constant at 0.6%. The tensile test results for aluminium (Al6061) composites reinforced with 0.6% nanographene and varying percentages of coconut shell ash (CSA) in 2% increments up to 8%. The tensile strength and yield strength generally increase with higher CSA content, indicating improved mechanical properties.
