Abstract
This work studied the thermal aging performance of HY-201 polyimide composite material for gas turbines under different temperature conditions to provide data support for engineering applications.The changes in morphology,mechanics,chemical structure,and other properties of HY-201 polyimide composite material were revealed through various characterization methods such as microscopes,universal testing machines,and Fourier transform infrared spectroscopy.The thermal stability of the sample was tested using a thermogravimetric analyzer.It was found that HY-201 polyimide composite material had excellent aging resistance and heat stability.According to the mechanical performance test results,HY-201 polyimide composite material could be used for a long time under thermal aging conditions of 100℃ and 120℃.
