The work focuses on the preparation of polymer matrix nanocomposite materials by hand lay-up, it was prepared from the unsaturated polyester resin as a matrix reinforced with a different weight percent of Magnesium oxide nanoparticles (MgO NPs(. This research includes studying the thermal analysis, (TGA, DTG, and DSC) for this nanocomposite material. Study of non- isothermal kinetics decomposition of (UP) and (UP/MgO NPs) nanocomposites were carried out by utilizing (TGA). The samples were heated from room temperature to (600°C) at a constant heating rate of (10°C/min) under an oxidative atmosphere using air. TGA and DTG curves obtained from the decomposition were analyzed using the Coast- Redfern method. Kinetic parameters were determined for all specimens that show a good correlation with the linear correlation coefficient. It was found that the Coast –Redfern procedure the best to obtain results in good estimate of the kinetic parameters.
