Abstract

A method for measuring out-of-plane wrinkles in composite laminates is described. An example method includes scanning a first side of a composite laminate with an ultrasonic transducer. The method further includes locating an out-of-plane wrinkle of the composite laminate on a B-scan ultrasound image generated in response to the scanning of the first side of the composite laminate. The method further includes associating a first marker with the B-scan ultrasound image, the first marker determined based on a location of a crest of the out-of-plane wrinkle on the B-scan ultrasound image. The method further includes associating a second marker with the B-scan ultrasound image, the second marker determined based on a location of a trough focal point of the out-of-plane wrinkle on the B-scan ultrasound image. The method further includes determining an amplitude of the out-of-plane wrinkle based on a distance between the first marker and the second marker.
