On the ultrasonic characterization of the stacking sequence of CFRP laminates Universiteit Gent
Ultrasound in pulse-echo scan mode has already been demonstrated for the extraction of local fiber angle dis-tribution in composite laminates. Depending on the ultrasonic (scan) parameters employed, different sensitivity, spatial resolution, and dynamic depth range can be reached. This study investigates the use of pulse-echo ultrasound testing in different frequency ranges to characterize the in-plane fiber angle distribution and ply stacking ...
