Auteur(s): Fantozzi, G.; Reynaud, P.
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
