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 major role of the fiber-matrix interphase in ceramic matrix composites (CMC) is to increase the composite fracture resistance; thus the properties of these materials are dominated by the interphase. To achieve this, the interphase is designed to provide friction sliding contact between fiber and matrix, which prevents fracture of fibers due to matrix cracking [1,2]. Due to the relatively low stiffness of the fiber-matrix interphase compared to fiber and matrix, the interphase also has a dominant effect on the transverse and shear stiffnesses of CMC materials [3]. Therefore, to obtain optimal performance in CMC materials quantitative characterization of the fiber-matrix interphase is necessary.
