AN IMPROVED LONG LIFE DURATION CERAMIC MATRIX COMPOSITE MATERIAL FOR JET AIRCRAFT ENGINE APPLICATIONS

A new concept of Ceramic Matrix Composite (CMC) material, mainly based on the use of a self–sealing technology for matrix and the use of a multilayer woven reinforcement, has been developed by Snecma for achieving high performance levels targeted by future jet engines. The driving force for this development has been to increase both lifetime and temperature capability of previous C/SiC and SiC/SiC composites materials using a monolithic SiC CVI matrix and finishing treatment against oxidation.
