The study reports development of graphene nanoplatelets reinforced aluminium A380 matrix nanocomposites using a powder metallurgy and were fabricated by Spark Plasma Sintering Furnace (SPS) technique in vacuum at 540 °C. 0.25, 0.5, 0.75 and 1% wt-% of graphene nanoplatelets are used for the synthesis of nanocomposites. Testing and analysis of fabricated composites revealed improved metallurgy, mechanical properties and wear behaviour. Grain refinement action caused by graphene, high hardness and graphene's self-lubricating nature is reasoned for these improvements. The microstructures are analysed through a scanning electron microscope. The wear resistance of resultant composites is reported at a higher side, decreasing friction coefficient owing to graphene's self-lubricating nature. Moreover, incorporation of lubricant grapheme nano sheets significantly reduced the wear rate and the friction coefficient in comparison with the AlA380 matrix composites.
