Abstract Scope Textile composites with ceramic fiber tows woven into complex 2D/3D architectures in a ceramic matrix are important material options for structural applications in hypersonic service conditions. Environmental barrier coatings further expand the capabilities for extremely corrosive environments. The hierarchical microstructural complexity of these materials pose significant challenges in their complete characterization. Lab X-ray microscopes present new opportunities for 3D non-destructive characterization and enable 3D and 4D investigations including in-situ studies. In this work, we conducted high resolution tomographic imaging of a model CMC system consisting of SiC fibers in SiC matrix. Multiscale imaging combining deep-learning based image reconstruction allows improving image quality for detailed investigation of crack networks. By combining additional microscopy modalities such as laserFIB and SEM, deeper insights can be obtained at much smaller length scales. Results presented will highlight the importance of applying combined microscopy and image processing workflows to fully characterize materials in extreme structural applications.
