Influences of heat treatments on the strength properties of amorphous SiC fibers

Amorphous SiC fibers are known to have larger failure strain than crystalline SiC fibers, thereby facilitating manufacturing of ceramic matrix composites (CMCs). In this research, for the purpose of clarifying the influences of heat treatment temperatures and time on the failure strength of amorphous SiC fibers, the factors contributing to the changes in the failure strength of ZMI fibers, a type of amorphous SiC fibers, were examined through...
