摘要： 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.

摘要： An apparatus for inspecting a tubular workpiece (200) may include a probe assembly (150) and a rotation mechanism (122). The probe assembly (150) may include a transducer array (150) positionable adjacent to an inner surface of the tubular workpiece (200). The probe assembly (150) may generate transmitted sound waves and may receive reflected sound waves. The rotation mechanism (122) may rotate the probe assembly (150) relative to the tubular workpiece (200) in a manner such that the transducer array (150) passes over the inner surface (214) in a circumferential direction (180) during transmission of the transmitted sound waves (166).
