In order to optimize the thermal stability of the polyepoxide matrix standard and industrial of the base, we developed composite and nanocomposite oxides with respect to the polymer's matrix, DGEBA and DGETBBA then DGETBBA and a very fine powder of Zn, following many formulations. The first formulation series are based on the mixture of the diglycidylether of bisphenol A (DGEBA) and diglycidylether Tetrabromo bisphenol A (DGETBBA), cross linked with methylene dianiline (MDA) as an enuring agent. In the second series, we have optimized the composition of a formulation based system DGETBBA / MDA and the inorganic filler in powder form based on zinc (Zn). The study of the thermal behavior of formulated materials was evaluated by thermogravimetric analysis (TGA) under dynamic conditions. The results show that the thermal stability was confirmed by the increase of the degradation onset temperature (TD) of the studied systems over standard macromolecular matrices.
