... loading. For example, in the case of an SCS-6 fiber, large residual radial stresses have been identified at various interfaces (e.g., the carbon substrate/pyrolytic graphite interface and the SiC/pyrolytic graphite interface) that produce structural defects in the fiber ( Ref 20 , 21 ). These stresses...
