The purpose of this study is to fabricate and characterise the aluminium matrix composite reinforced with graphite through stir casting process. Composites and Functionally Graded Composite Materials (FGCMs) are one of the potential and advanced classes of engineering materials, which exhibits gradual transitions in the microstructure and/or the composition in a specific direction leading to variation in the functional performance of a component.  The objective of the present investigation is to fabricate and characterize graphite hybrid particle reinforced aluminium functionally graded composite. Gravity casting was used for making hybrid composite and centrifugal casting method was used for making functionally graded hybrid (primary silicon and graphite) composite. the results showed the movement of graphite particles towards the inner region in centrifugal cast and also showed the dendrite structure in gravity cast specimen
