An investigation of two nondestructive methods (ultrasounds and infrared thermography) is carried out. The defect detection by both methods is first examined. The determination of the position and dimensions are then studied. And finally, the feasibility and the time of the experimental protocol setting up is analysed. The aim is to compare two nondestructive methods: ultrasound and infrared thermography applied to composites samples. So, three different specimens are tested. It appears that the majority of the defects are detected very quickly with infrared thermography compared to ultrasounds method. However, certain defects are not visible by thermography IR.
