Scatter dark field imaging with an X-ray grating interferometer has been implemented to probe the micro-structure of polymers, fibre-reinforced composites or light metals. The method has now been developed further to enable the characterisation of the fibre laminate structure. Experimental results obtained by scatter dark field computed tomography illustrate how information on the microstructure such as micro-cracks density and weave pattern can be gained. Future developments of the technology aim at increasing the size of the field of view and improving the robustness.
