The thermal characterization of hybrid metal matrix composites is increasingly important in a wide range of applications. Thermal Analysis of Metal Matrix Composites is required to clearly examine the thermal properties viz., Thermal Conductivity, Temperature Difference, Thermal Capacity or Heat Difference, Coefficient of Thermal Expansion (CTE) and Rate of Heat Transfer. Thermal studies of composite materials are gaining greater impetus in the present scenario. This will help to understand the properties of materials as they change with temperature. It is often used as a term for the study of heat transfer through structures. The assessment of thermal parameters of composites will benefit to evaluate heat capacity, variation in the intensity of heat, heat diffusion and heat release rate. In the present scenario, research work is accomplished on hybrid composites based on thermal expansivity and specific heat capacity using Dilatometer and Differential Scanning Calorimeter, as limited research has been carried out on hybrid composite based on thermal properties. The coefficient of thermal expansion is one of the most important properties of MMCs. Since nearly all Metal Matrix Composites are used in various temperature ranges, measurement of CTE as a function of temperature is necessary in order to know the behaviour of the materials. The heat flow and heating rate are beneficial in the estimation of specific heat capacity for different percentage compositions of the hybrid composites. This technical paper emphasizes the experimental evaluation of CTE and specific heat capacity using encomiastic experimental techniques.
