Composite materials are now widely used in engineering application and the scope of its application is widespread mainly for its contrapuntal properties. In this research work composites were prepared by crosslinking the polyester resin with Methyl Ethyl Ketone Peroxide and finally reinforced with the Granite scrap powder. Granite stone as filler was used at 20%, 30%, 40% and 50% with respect to the weight of unsaturated polyester resin with styrene monomer at 7.5% as constant basis mentioning that 0% sample (without Granite Filler) was also prepared to compare the results with it. Thermal analysis of the prepared composite such as Thermo Gravimetric Analysis (TGA), Thermo-mechanical Analysis (TMA) and Thermal Conductivity of the composites were analyzed along with the SEM analysis to find out correlation between thermal properties with composite surface topology. Thermo gravimetric analysis is done to determine the kinetics of thermal degradation and Thermo mechanical analysis is to determine expansion co-efficient along with Tg of polyester resin and granite blends composite. To avoid the thermo-oxidative degradation, thermal analysis was carried out for samples in nitrogen atmosphere at heating rates of 20°C/min. Thermal Conductivity analysis is performed to determine the ability of the composite to conduct heat at various temperatures.
