Abstract

Lamb-waves can be used to detect disbonds in composite plates. In this work, a photoacoustic technique was first applied to measure the dispersive property of a GLAss-REinforced (GLARE) composite panel. The measured phase velocity dispersion curves are consistent with the theoretical calculation using the classical transfer matrix method for layered media. Based on the obtained properties, a finite element method (FEM) model was constructed to study the influence of a disbond void on the Lamb wave propagation in the GLARE plate. It is found that the displacement amplitudes of the Ao mode Lamb wave decrease while its travel time increases as the disbond size increases.
