Paper Abstract

Guided wave ultrasound is well suited for inspection of laminate composite structures. Compared to nearly flat or gently curved composites, performing accurate NDT on sharply curved structures is more complex with standard ultrasound test methodologies, such as pulse-echo methods. Ultrasound propagation in curved composite structures is investigated for sharply curved geometries. Responses are predicted based on dispersion models. Experimental results are presented on 0.25 inch thick curved carbon fiber reinforced plastic (CFRP) composite geometry of an aircraft structural component and compared with predicted values.
