Steady-State Creep Of 1-D-C/C with pyrolytic carbon matrix

摘要

The tensio steady-state creep behavior of 1-D-C/C with pyrolytic carbon matrix was investigated at tgigh temperatures up to 2160 degree and at a stress from 133.83 to 213.46 MPa. Based on the creep experiments of single spcecimen method, the apparent activation energy and the stress exponent was determined for steady-state creep by the use of a self-made apparatus and a auto-testing system. Values of apparent activation volume is provided and the creep mechanism has also been discussed.
