Identification of microscale ablative properties of C/C composites using inverse simulation

Yvan Aspa; Michel Quintard; Jean Lachaud; Gerard L. Vignoles

The objective of this work is to obtain, by an inverse approach, the reactivity of microscale components of ablative C/C composites. A model has been built for micro-scale ablation and a has been numerically implemented using a VOF method. The application of the approach is illustrated by the identification of reactivities from recession data and SEM observation of the ablated composite surface.
