OS05F113 Nondestructive Evaluation of Advanced Composites using X-ray CT Scanner

Abstract

Micro-Focused X-Ray CT Scanner has been used for nondestructive evaluation of composite materials at Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency. Some successful examples of NDE of composites using Micro CT will be presented in this presentation. One example is debonding of fiber/matrix interface, splitting of fiber bundle and matrix crack in carbon/carbon composite. Another example is NDE of stitched CFRP. It was easy to evaluate state of stitch fiber. It has been demonstrated that Micro CT is a powerful device for detecting small damage/flaw in composites, such as delamination, matrix crack and void.
