In the present study, we performed three-dimensional observation and analysis of strain distribution for all-oxide ceramic matrix composite (CMC) using X-ray computed tomography (X-CT) and digital volume correlation technique (DVC). For testing, uni-directionally (UD) reinforced oxide matrix CMC was used for model material. Mechanical properties of the composites fabricated under two different conditions were characterized. Damage evolution during loading was successfully visualized by volumetric image and image analysis combined with deep learning. The results revealed that interlaminar failure occurs during loading. The results of strain distribution is in good agreement with 3D observation.
