摘要：

The creep behaviour of a SiC/Si-B-C composite at 1200 degreesC in argon is investigated under static and cyclic loading conditions. The SiC/Si-B-C composite consists of a multilayered self healing matrix reinforced with Nicalon fibers. It was produced via chemical vapor infiltration (CVI). The creep behaviour is examined with respect to the extent of damage created during an initial step of monotonic loading and controlled through the applied strain. The creep rate is shown to be dictated mainly by creep of fibers and interfacial debonding, whereas no significant creep induced matrix cracking was detected. (C) 2002 Elsevier Science Ltd.
