Long-range ultrasonic nondestructive evaluation of composite tubulars Conference Paper

abstract

• We report the development of a technique for the qualitative long-range ultrasonic nondestructive evaluation (UNDE) of composite tubulars. A piezoelectric transducer was used to excite Lamb waves, which propagate very long distances in the axial direction. The field scattered by a defect is measured through the use of a laser vibrometer. The technique was tested on graphite/epoxy and glass/epoxy composite pipes. It is shown that small defects in the pipe wall may be detected at a distances on the order of one meter from the transducer.
