Composite material is a combination of two or more materials having compositional variations and depicting properties distinctively different from those of the individual materials of the composite. Aluminum hybrid reinforcement technology is a response to the dynamic ever increasing service requirements of such industries as transportation, aerospace, automobile, marine, etc. Manufacturing of aluminum alloy based casting composite by stir casting is one of the most economical methods of processing MMC. In present work we aim to manufacture composite material by reinforcing Al alloy with Al2O3 and fly ash particles. The wettability between all these materials is assured by stir casting process. Aluminium alloy A356 is uses as matrix material and hybrid reinforcement of Al2O3 and fly ash which is industrial waste. Reinforcement added in different percentage by weight of matrix material. Casting was made in rectangular permanent metallic mould having dimension 220x220x20mm3.These rectangular plate castings were used for further mechanical studies.

Keywords: Aluminium Matrix Composites (AMCs), Stir casting, Particulate Reinforcement, Hybrid Composite.
