Ceramic woven textile composites represent a new class of integrally woven composites for high-temperature applications, where both strength and thermal conductivity are important. For high performance and reliability, a key issue is geometrical defects in the textile reinforcement, which trigger failure mechanisms and compromise strength. Due to the intricate 3D architecture of woven composites, damage initiation, propagation and failure is extremely challenging to investigate. 3D x-ray microscopy allows non-destructive imaging of the sample under simultaneous in-situ mechanical loading in the laboratory. Particularly for woven composites, it provides rich data that resolves cracks initiated at several different sites under load. We present results obtained on a 3 layer angle-interlocked woven composite subjected to in-situ mechanical loading. Through successive tomographic scans collected at different loads, the crack extension was tracked. These results provide 3D experimental data further useful to validate the fidelity of predictive modeling codes that simulate failure in composites.
