Abstract
This paper describes ongoing work into the use of acoustic Lamb waves for composite material characterization. Particular emphasis will be placed on the use of optical fiber based sensing techniques. Previous work described by the authors has concentrated on the utilization of optical fibers for the detection of acoustic waves in composite plates, and the subsequent evaluation of the acoustic signature to gauge damage in the material. In this paper we intend to explore materially integrated techniques for effective acoustic wave generation.
