Main project: Characterization and modeling of surface mechanical properties at the micro-nanometer scale for the study of polymer and composite behavior in contact with industrial fluids
Supervisor(s): Thomas Pardoen
Currently the characterization of the mechanical properties of polymers after ageing with fluids is long and costly, as it is essentially based on the macroscopic characterization of saturated samples. In this context, the objective of the project is to exploit the potential of local methods to evaluate the evolution of the surface mechanical properties, through nanoindentation and atomic force microscopy (AFM), and to establish assessment protocols for the quantification of the impact of fluids on mechanical properties. With these local methods, the aging time could be reduced from months to a few minutes.
To achieve this objective it will be necessary to establish a modeling strategy based on a micro-mechanical basis. The aim of the modeling approach is to link nano- and microscopic measurements to the elasto-viscoplastic properties and to understand the root causes of the fluid impact on physical mechanisms.
