The current project work lays emphasis on the manufacturing and mechanical testing of an aluminium, Silicon Carbide, fly ash hybrid composite. The metal matrix selected ware aluminium and fly ash, Silicon Carbide constituents in different percentage composition were reinforced in it to manufacture the required hybrid metal matrix composite (MMC).Stir casting method was used to manufacture the MMC with (0, 2.5) (2.5, 0) (2.5, 2.5) % weight of fly ash and Silicon Carbide constituents in aluminium. Tribological analysis of the tribopairs formed between the smooth surfaces of cast iron disc and smooth MMC pin has been taken into consideration, friction force and wear of the MMC were evaluated by using a Pin-on-disc setup. Furthermore the morphological study and mechanical properties were evaluated as per ASTM standards. It was observed that the MMC with (2.5, 2.5)% weight of fly ash and SiC content in aluminium matrix results in higher hardness value and it is also noticed that the hybrid MMC shows very superior wear resistant properties and can be used in applications of disc brakes of two wheeler automobiles.
