Abstract

This paper describes the integration of piezoelectric ceramic transducers within a carbon fibre reinforced polymer composite plate for the generation of a pure, zeroth order symmetric ultrasonic Lamb wave. The lateral dimensions of the transducers were in the order of 5mm - 12mm, which were considered suitable for practical embedding purposes. The composite plate configuration used throughout is an uni-directional structure, with the transducer embedded exactly within the centre. The mechanical integrity of composite plates was measured through both conventional c-scans and four point flexural tests. Importantly, degradation of the flexural modulus is shown to be less than 10% for the embedded transducer configuration. Finally, the transducer was observed to continue operating in pulse-echo mode when a load in excess of 3500N was applied to the plate structure.
