Abstract
Since the early eighties Snecma Propulsion Solide (SPS) pioneered development into the Ceramic Matrix Composites (CMC) to increase the durability of the Carbon-Carbon materials in oxidative environment. Because aircraft engine application are aimed, long life endurance of thousands hours in operation are needed. Moreover, CMC very high temperature resistance much more over current metallic alloys capacities, allows to increase performance and comply with new environmental constraints requested for future aircraft engines. SPS has now a palette of industrial CMC materials relevant for aircraft engine applications as for nozzle mixers, nozzle plugs, flaps, etc…
