Workshop: Rheology In Composites Processing, Nantes, September 2017

Over the last decades, an increasing number of functional and structural parts has been reengineered by replacing metallic materials by polymers, reinforced polymers and composites. The motivation for this substitution may be the weight reduction, the simpler, cheaper or faster forming process, or the ability to exploit additional functionalities.
The fillers usually employed cover a broad range involving many scales: (i) the nanometer scale (e.g. carbon nanotubes, graphene); (ii) the micrometer to the millimeter scale (particles and short fibers); (iii) the centimeter (e.G.SMC patches); and (iv) the macroscopic scale (continuous fibers arranged in bundles).
In the case of continuous fiber reinforced polymers, the impregnation of the reinforcement with a low viscosity polymer involves the flow of a (non-)Newtonian fluid in the complex multi-scale microstructure related to the fiber and tow arrangement. The use of nano-charges raises new challenges such as dispersion of charges into the polymer matrix involving aggregation and disaggregation mechanisms.
In this workshop we expect covering advanced technics related to the multi-scale modelling and simulation of polymers, reinforced polymers and composites processes, involving flowing microstructures and flows inside a nearly stationary multi-scale microstructure.
