Résumé: Ceramic-matrix composites (CMCs) are interesting materials for aeronautic applications because of their good mechanical properties at high temperatures even under air. Contrary to bulk ceramics, CMCs have a non-brittle mechanical behaviour due tothe high strength of fibres and to optimized fibre/matrix interactions after matrix multi-cracking. Interactions between fibres and matrix act mainly at the interface level. When fibres and matrix are debonded, fibres slide with friction andenergy dissipation occurs. By using a shear-lag model, the energy dissipation can be calculated andthe evolution of the fibre/matrix interaction can be followed during fatigue. 2011-01-01T00:00:00Z
