Cover Story: SiC/SiC composites are promising structural materials for improving the performance of next-generation nuclear power systems, aero-engines, or land-based gas turbines. The influence of the interphase characteristics still needs to be clarified to optimize the mechanical performances. While the influence of its thickness is quite understood, the influence of its microstructure/texture must be explored. This work clearly demonstrates that the weakest interface is the fiber/interphase (F/I) interface, regardless of the PyC interphase thickness or texture. Moreover, control of pyrocarbon microsturture/texture allows monitoring F/I bonding strength. A highly anisotropic PyC interphase leads to cohesive failure (higher bonding strength), whereas lowly anisotropic PyC interphase leads to adhesive failure of the F/I interface (lower bonding strength).
