Abstract
This paper presents some creep results performed at the LERMAT laboratory o n monolithic ceramics and on ceramic matrix composites: TiC, SiC-Al, 2D SiC f-MLAS and 2.5D C-f-SiC. It is shown that if for ceramics classical creep m echanisms are involved, i.e. dislocation or diffusion creep, or grain bound ary sliding, in the case of ceramic matrix composites the damage-creep mech anism appears the most realistic process to explain the creep behavior of t hese materials, if the applied stresses and temperatures are not high enoug h to provoke dislocation motion, diffusion or grain boundary sliding.
