The temperature was monitored by infrared spectrometer within ±2℃. Calculational results indicate that the activation energy is 84.8 kJ / mol and activation volume is 0.754 nm_3. The creep friction stresses are 127, 115, 95.6 and 90.3 MPa at 1900, 2050, 2200 and 2350℃ respectively. By extrapolation of the temperature dependence upon zero creep friction stress, the temperature seems to be about 3375℃ just to approach the sublimation one of carbon.(Correspondent: QIAO Shengru, associate professor, Faculty No.401, Northwestern Polytechnical University,Xi'an 710072 ) Key words:  unidirectional carbon/carbon composite      high temperature creep      creep friction stress      creep activation energy      creep activation volume      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1994/V30/I23/524 1BuckleyJD．ceramBull,1988;67(2):3642FitzerE．Carbon．1987;25:1633SinesG,YangZ,VikersBD．Carbon,1989:27:4034SinesG,YangZ,VikersBD．ActaMetall,1989;37:26735SinesG,YangZ,VikersBD．JAmCeramSoc,1989;72(1):546HawthorneHM,JMaterSci,1976;(11):97 [1] HOU Jieshan; ZHANG Yulong; GUO Jianting; JI Guang; ZHOU Lanzhang; YE Hengqiang.
