Abstract
Thermal characterization and analysis of composite materials have been gaining greater importance. Thermal an alysis of composites will be beneficial for comprehending the properties of materials as they change with temperature. The determination of thermal properties of composites have been constructive for the evaluation of thermal capacity, variation in the intensity of heat, heat diffusion and heat release rate. It has been customary to control the temperature in a predetermined way either by increase or decrease in temperature at a constant rate by the processes of linear heating or cooling. The thermal characterization of composite materials will depend on the factors that persuade on the thermophysical properties. It is a major challenge as composite materials are susceptible to the type of reinforcement and method of manufacture. The decisions based on the selection of materials for components are exposed to temperature variations and thermal gradient. For aerospace and automotive applications, low density, low coefficient of thermal expansion, moderate thermal conductivity and high electrical conductivity of composite materials .Hence it is mandatory for the design engineer to have a lucid comprehension about the thermal responses and characterize the thermal properties of a broad assortment of materials. Thermal analysis of composite materials are essential to examine the thermal properties viz., specific heat capacity, enthalpy, thermal diffusivity, thermal conductivity, temperature potential, thermal expansivity, latent heat, thermal displacement, thermal strain, thermal stresses, thermal gradient, thermal flux, rate of heat flow, and thermal shock resistances based on experimental and numerical approaches. This research paper emphasis the relevance and research scope of experimental and numerical thermal analysis of Aluminium hybrid composites
