| Research Abstract |
This study investigates mechanism of the high-speed impact damage of 2-dimensional plain-woven ceramics-matrix-composites (CMC) in order to evaluate the reliability of the woven CMC for the foreign object damage (FOD). The damage patterns were observed in detail, and we clarified the FOD mechanism and found that the specimens with thermal load over 1000°C were significantly embrittled. We also developed a fracture simulation using a particle method, which could analyze the large deformation and the spall fragment. The FOD mechanism of a brittle material was then investigated by the particle simulation method.
