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.

Abstract
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.

Abstract: (french)
Dans le but d'optimiser la stabilité thermique de la matrice polyépoxydes standard et industrielle de base, nous avons élaboré un composite et nano-composite respectivement à matrice de polymères oxydes, DGEBA et DGETBBA puis DGETBBA et poudre très fine de Zn, suite à de nombreuses formulations.
La première série de formulation repose sur le mélange de la diglycidyléther de bisphénol A (DGEBA) et la diglycidyléther de tetrabromo de bisphénol A (DGETBBA), réticulé par le méthylène dianiline (MDA) comme agent durcisseur. Dans la seconde série, nous avons optimisé la composition d'une formulation à base de système DGETBBA/MDA et la charge minérale sous forme de poudre à base de zinc (Zn).
L'étude du comportement thermique des matériaux formulés a été évaluée par l'analyse thermogravimétrique (ATG) en régime dynamique. Les résultats obtenus, montrent que la stabilité thermique est confirmée par l'augmentation de la température de début de dégradation (TD) des systèmes étudiés par rapport aux matrices macromoléculaires standards.
Author Keywords: Formulation, composite, nanocomposite, matrice époxyde, DGETBBA, DGEBA, MDA, zinc et stabilité thermique.
