In thiswork, we are interested in the study of radiochemical aging formulations of two epoxy composites with an epoxy resinmodel of diglycidylether of bisphenolA(DGEBA) crosslinkedwithmethylene dianiline (MDA),which contains as filler carbon black (CB) and the glass powder (GP). Then we highlighted the thermal and radiochemical composites made by differential scanning calorimetric (DSC) and Fourier Transformer Infrared (FTIR). The study of this thermal and spectroscopic behavior shows an improvement in terms of performance thermal, mechanical and radiation hybrid materials made from the unfilled matrix. Monitoring changes in bands oxidation products has enabled us to establish a mechanism for radiooxidation after irradiation.
