Mechanism of cumulative damage to short fiber type C/SiC under tension

Study on the Mechanical Property of High‐Performance Silicon Carbide Fiber

“…[9,10] After that, the study has been developed rapidly, and so far, SiC fibers have been developed for the third generation. [11,12] First-generation fiber is rich in oxygen and carbon elements, whose oxygen content is about 10% (w) and contains part of SiC x O y phase and free carbon, which, at higher temperatures, causes many defects such as holes and cracks inside the fibers, resulting in a sharp decrease in the mechanical properties of the fibers. [13] Second-generation fiber has low oxygen and high carbon content.…”
