The industrial application (not described for confidential reasons) needs the assembly of a ceramic piece and a steel one. This PhD research work aims to provide a reliable industrial bonding between ceramic and steel substrate using structural adhesive. This industrial joint shall withstand a wide range of temperature with pretty brutal thermal changes and also severe humidity conditions. As prerequisite to this bonding assembly qualification, the purpose of this work is the study of the durability, in a hot-wet environment. Depending on the formulations, we observe different behaviours in term of weight uptake, morphological, thermomechanical and chemical modifications of the epoxy network.
