Ceramic matrix composite material structure temperature testing method based on optical fiber sensor
The invention relates to a ceramic matrix composite structure temperature testing method based on an optical fiber sensor, and belongs to the technical field of aero-engine testing. According to the method, a high-temperature-resistant ceramic composite coating is prepared on the surface of a curved part made of a ceramic-based composite material base material to mount and fix a flexible optical fiber sensor, and the structural temperature of the part made of the composite material base material is tested through a temperature fitting curve obtained by calibrating test data of the optical fiber sensor in advance. The method can be used for testing the structure temperature of a ceramic matrix composite material curved surface part for a next-generation aero-engine in a high-temperature working environment, and effective data support is provided for development, verification and improvement of related materials and parts.
