Carbon fibre reinforced polymer (CFRP) is an extremely strong and lightweight
plastic of which the strength depends on the distribution of its fibres. Fibre bundles can be
visualized by means of phase contrast X-ray computed tomography (PCCT) based on
grating-based interferometry (GBI). However, many steps are involved in the reconstruction
of GBI-PCCT images. In this abstract, a workflow for the reconstruction of 3D CFRP phase
contrast images based on GBI projection data is presented.
