摘要：
The tensile creep tests of SiC fiber reinforced SiC composites at 1000-1300 C were conducted. The apparent stress exponent and activation energy for creep increase with a decrease in stress. The threshold stress approach was used to interpret the experimental data. Creep of SiC matrix is attributed to the rate-controlling process for the creep of the SiC/SiC composites. Creep fracture mechanism and life prediction method were also discussed.
