2. Influence of thermal stress on CMO behavior
Thermal attack on a CMO takes place in two phases. As the temperature rises, the material first undergoes thermal degradation. Defined by the ISO 13943 :2017 It is "the process by which the action of heat (...) causes a deterioration (...) of several properties". More generally, it can be seen as a temperature-related modification of thermophysical and mechanical properties. Secondly, it undergoes thermal decomposition, which corresponds to the set of mechanisms that lead to changes in its chemical structure (chain breakage, oxidation, formation of decomposition gases, pyrolysis, etc.).
