From images to property computations in carbon/carbon composites at three scales
Gérard VIGNOLES, UNIVERSITE DE BORDEAUX

Carbon/carbon composites have outstanding mechanical and thermal properties at extreme temperatures, and consequently usages in the aerospace domain (propulsion, braking, atmospheric reentry).

Their design rests on a sound knowledge of the properties of their constituents and their arrangement in space. This is a particularly difficult task, due to the complexity of this arrangement.

We propose to review some approaches at several scales (molecular scale, fiber-scale, composite scale), based on imaging and computations in large domains built from these images. These methods are potentially very greedy of numerical resources.  They allow understanding the impact of the arrangement of the constituents on the global material behavior and hence a better design through virtual materials techniques.
