XCT provides 3D information on the internal composite structure. The X-ray attenuation contrast between the fibres, matrix and voids allows segmentation, visualization and quantitative analysis (volume fraction, fibre orientation, etc.) of the different phases. Furthermore, deformation and mechanical damage of in-situ loaded samples can be detected by 4D-XCT and quantified by digital volume correlation, a technique that is able to calculate full 3D displacement and strain fields by correlating the subsequent load-steps with the reference volume.
