Failure behavior of interfacial domain in SiC-matrix based composites

In this work, the microstructure, failure behavior and interfacial properties with respective to the interfacial domain in SiCf/BN/SiC and Cf/PyC/SiC composites were studied via the fiber push-in test. The differences in the mechanical response of the interfacial domain were observed. During the fiber push-in test for SiCf/BN/SiC, the interface debonding accompanied with interphase fracture occurred, resulting in an obvious sign of the onset of...
