Abstract
One of the promising methods for thermal nondestructive testing of products made of polymer structural materials (PSMs) is vibrothermography, i.e., when the thermal excitation of a test object is performed using mechanical vibrations at sonic or ultrasonic frequency and the change in the temperature field of the object is monitored by thermography methods. The paper considers the testing procedure and presents the results of thermographic studies during vibration strength tests of PSM products with impact damage.
