Fatigue of 2D woven ceramic composites at high temperatures
Fatigue of continuous fibre reinforced ceramic matrix composites (CMC) is currently receiving a lot of attention. The main efforts have been focused on the low temperature tension-tension behaviour. It is now well established that the in-situ fibre strength as well as interfacial frictional sliding and wear dominate the fatigue response under these conditions. The present investigation aims at extending this understanding to the intrinsic, environment-independent, fatigue behaviour at high temperatures. Uniaxial tests are performed under high vacuum and the evolution of the hysteresis loops in terms of shape, width and apparent stiffness is followed with the aim of characterizing the damage processes occurring under high temperature fatigue loading.
