THE APPLICATION RESEARCH OF NEW TESTING TECHNIQUE ON MECHANICAL EXPERIMENT FOR LARGE-SIZE CMC STRUCTURE

摘要

In this paper, the challenge in respect of high-temperature experiment and thermal-strength test is introduced for the application of CMC structure. Aimed at the two difficult points in the condition of high-temperature environment, which are the measurement problem in dynamic test and the disfigure check problem in strength coupling test, the characters of wireless measuring technique using laser equipment and acoustic emission technique(AE) in high temperature are discussed. Then, the application in these two aspects is introduced and the developable direction about these researches in the future is pointed out.
