摘要
In this paper, the creep resistance of 2D braided SiC/SiC composites was studied under the stress conditions of 120MPa and 140MPa at 1200℃. The creep curve is obtained through the experiment. Through the analysis and calculation of the creep curve, the material has excellent creep resistance in the environment of 1200℃ and 120MPa, and the creep resistance is reduced due to higher stress in the environment of 1200℃ and 140MPa. Through calculation, the average creep rate of the materials under the two stresses is (5±1) × 10-8/s, (1.6±0.6) × 10-7/s respectively, and the creep rate is increased by 3.2 times under 140MPa stress.
