abstract The inner material structure as well as voids and damages in composite materials have a significant influence on mechanical material behaviour. Thus, for a reliable application of composites in safety relevant lightweight structures, knowledge of the inner material structure is of utmost significance. Computer tomography is an especially important part of nondestructive testing (NDT) both in research and industrial applications for non-transparent composites. Besides that, a novel in situ CT which enables the preparation of tomograms of specimens under loading conditions offers a better understanding of damage processes in composites. The paper gives examples for the advanced analysis of fibre-reinforced composites and their degradation behaviour using novel CT systems. The advantages of high resolution CT scans as well as corresponding FEM results are shown and an overview of the numerous application possibilities is given.
