Porosity analysis of long-fiber-reinforced ceramic matrix composites using X-ray tomography

This study has been devoted to a volumetric exploration of the meso-structure of a two-dimensional SiCf-SiC composite with cross-weave fibers using X-ray tomography. A series of projection images have been used to reconstruct the three-dimensional composite's architecture and a quantitative analysis of the morphology of the porosity network has been carried out in order to characterize the fiber-tissue structure. The suitability of X-ray tomography for characterizing this structural material at a meso-scale level is critically assessed
