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 …

In-situ stepwise and dynamic imaging Time-resolved imaging is a necessity in our research, as many processes we study under compression, tension, bending, imbibition, or during heating, are time dependent. Time is, therefore, the fourth dimension (4D-XCT)to be considered. Depending on the specific research, the changes to the microstructure can be relatively slow (hours or even …
