The study of composites behavior in conditions of use is naturally multi-scale and multi-physics.
Mechanic tests give access to strain modes and damage and failure mechanisms. A large part of the studies is devoted to the influence of environment on the fatigue behavior and on lifetime. As a complement, studies on the chemical evolution of the materials without applied stresses are also conducted, with variations on the external conditions (pressure, temperature, composition of the aggressive atmosphere), in order to identify the relevant mechanisms. These works have led the lab team to develop specific testing apparatuses like a high-temperature tensile testing stage under synchrotron X-ray exposure, with fruitful partnerships with facilities like ESRF, Soleil, SLS and the characterization platform Placamat.
