Nondestructive testing of carbon-carbon composite plate by thermal method and laser vibrometry with 12 impact damages of the same energy were carried out. Thermograms and distributions of vibrations from the plate surface at its heating and acoustic excitation are obtained. Complex diagnostics made it possible to detect all available defects by synthesizing data, as well as to increase the accuracy and informative value of quality control. It is shown that the control efficiency depends on the side of the plate selected for shooting, the type of method used to process the obtained data in the thermal control, as well as on the choice of the direction of acoustic wave movement when using laser vibrometry.
