Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

The present paper is concerned with the ultrasonic inspection of composite panels, fabricated by attaching a thin (<1mm) layer of aluminium to a rigid foam substrate using an epoxy resin, and of composite materials, consisting of aluminium sheets bonded together with an epoxy adhesive layer. These materials are represented schematically in Figs. 1(a) and 1(b) respectively. The characterization of such materials involves the detection of a delamination at an aluminium/epoxy interface, and the measurement of the properties of the epoxy layer, which may be affected by curing conditions and chemical composition.
