Book excerpt: This report describes an evaluation study for the application of stereo-X-radiography as a tool for three dimensional visualization and quantitative assessment of mechanical damage in graphite-epoxy structural materials. Comparison of image quality produced using X-ray opaque liquid penetrant materials was made for stereo-X-radiographs of panels that contained mechanical damage. A new X-ray opaque penetrant material was formulated and used for development of a high resolution stereo-X-radiographic technique. The technique was used to document damage accumulation in a series of pre-damaged panels during incremental tension-tension fatigue loading. The high resolution technique was shown to be useful in assessment of accumulated damage and in quantitative location of the damage within a panel. Features of the technique include use of a new X-ray opaque penetrant formulation, use of a unique penetrameter, 'soft radiation' and a fine grained X-ray film.
