Material mechanical property testing device and method under high-temperature gas environment
By designing a material mechanical property testing device under high temperature and high pressure environment, and adopting a double-wall structure and high-pressure cooling system, the problem of existing equipment being unable to simulate high pressure characteristics and unstable flow rate was solved. This enabled accurate mechanical property testing of CMC materials under high temperature and high pressure environment, ensuring the authenticity and accuracy of the test data.
