Long-term behavior

The study of aging requires multidisciplinary skills and covers the following fields:

• Accelerated aging allowing for the simulation of different environments (oxidant, thermal, photochemical, radiochemical, hydrolytic, in contact with fluids, under ozone, under mechanical stress), on specimens or on parts.

• Characterization of aging (properties, mechanisms and gradients) in order to establish the structure / property relationships of aged materials.

• Kinetic modeling (Arrhenius, WLF) for forecasting long-term behavior and providing accelerated aging protocols which are representative of the parts.
