Effect of Microstructure on the Mechanical Behavior of Continuous-Fiber-Reinforced Ceramic-Matrix Composites
The mechanical behavior of a unidirectional continuous‐fiber ceramic‐matrix composite (CFCMC) was correlated with matrix‐rich channels in the microstructure. A large population of CFCMCs was prepared via alkoxide infiltration, which incorporated either uncoated Nicalon fibers (64 samples) or BN‐coat...

Zusammenfassung: | The mechanical behavior of a unidirectional continuous‐fiber ceramic‐matrix composite (CFCMC) was correlated with matrix‐rich channels in the microstructure. A large population of CFCMCs was prepared via alkoxide infiltration, which incorporated either uncoated Nicalon fibers (64 samples) or BN‐coated fibers (118 samples). No structure/property correlation was observed for the uncoated composites, because of the uniformity of the microstructure. For the BN‐coated composites, both the flexure strength and work of fracture (WOF) were correlated with oriented matrix‐rich channels. The channels were |
