Abstract

The results of CFRP samples ultrasonic inspection during low-cyclic fatigue testing are  given in this article. It is established that for ultrasonic pulse-echo inspection during cycling mechanical testing and after the special correction of flaw detector’s gain and inspection’s sensitivity concerning back-wall echo decreasing in compare with testing specimen is necessary.
