Summary

Novel Ceramic Matrix Composites (CMC), consisting of a multilayer woven, carbon interphase and a self sealing matrix has been developed by SNECMA for achieving high performance levels targeted by the jet engines development programs. The main drive of this development has been to increase both life time and temperature capability of previous SiC/SiC using Nicalon and a CVI SiC matrix, and more particularly to bring a composite useable beyond its mechanical yield point. The approach retained for the composite development has been to work first on the material components and, during a second phase, with selective criteria based on tensile/tensile fatigue tests, to combine them at the composite level. Basic thermal and mechanical properties have been measured on the selected material CERASEP® A410. This composite has also been submitted to extensive cyclic loading at high temperature, taking into account environmental effects, in order to study damage accumulation resulting from mechanical fatigue and oxidation, and to evaluate the life time duration. Moreover, subelements attempt to meet design requirements relative to shapes, clamping, attachment concepts and the most important point concerns manufacturing feasability. Some subelements have been produced and tested.
