    Abstract

    The results of an experimental study of penetrant enhanced stereo X-ray radiography for damage documentation in resin-matrix composite materials are presented. The results show that penetrant enhanced stereo radiography can describe accurately the spatial distribution of matrix cracks and delaminations. Presence of fiber fractures can be inferred from the matrix cracking patterns.
