UNSPECIFIED. (1994) LAMB WAVE TOMOGRAPHY OF ADVANCED COMPOSITE LAMINATES CONTAINING DAMAGE. ULTRASONICS, 32 (2). pp. 83-89. ISSN 0041-624X

Abstract

Ultrasonic techniques have been used to image damaged regions in two polymer composite plate samples. The two thin laminate samples studied consisted of 16 layers of carbon-fibre reinforced epoxy with a quasi-isotropic lay-up configuration and had been previously loaded in a biaxial test method until failure. The resulting damage, in the form of fibre failure, matrix cracking and delamination, has been imaged using a novel Lamb wave immersion tomography technique. Images created with this method were correlated with images obtained from C-scan techniques. Both C-scans and Lamb wave tomography were able to identify clearly regions of damage in the two samples.
