Comparative study of Pulsed IR Thermography and Ultrasonic Testing to obtain a porosity mapping of oxide/oxide CMC specimens
Résumé
In this paper, a Non Destructive Testing approach by active infrared thermography is used to investigate porosity in oxide/oxide CMC specimens. In this study, an experimental bench is developed using pulsed thermography in reflection or transmission modes coupled with transient heat transfer modelling in order to detect inhomogeneities. Results obtained are discussed and compared to ultrasonic testing which is commonly used in Non Destructive Tests.
