Abstract: Metal Matrix Composites (MMCs) are the competitive and proficient materials that possess natural opportunities for modern material science and development. The mechanical, tribological, thermal and machinability properties of composite materials are extensively pertinent for aerospace and automotive applications. In this paper, the determination of density, volume fraction and porosity has been carried out successfully. In the research, Al 6061 is the matrix alloy and Silicon Carbide and Graphite are the reinforcements considered, being fabricated using stir casting technique. Microstructural analysis has been carried out using Scanning Electron Microscope to examine the distribution of the reinforcements. Finite Element Analysis (FEA) has been used to simulate the thermal and mechanical behaviour of Metal Matrix Composites. Computational simulation for the investigation of thermal properties of hybrid metal matrix composites has been performed depending on the variation in volume fraction of hybrid MMCs. To carry out computational modelling, the experimental values have been used to show the temperature distribution and heat flow distribution characteristics, being considered as the salient thermal properties of composite materials.
 
Keywords: Metal matrix composites, material science, volume fraction, porosity, microstructural analysis, finite element analysis, computational modelling and heat flow distribution.
