Abstract : Carbon yarns and composites were subjected to creep under tensile loading at 2000 to 3000 C. Changes in microstructure accompany changes in the apparent modulus of filaments and composites, as measured by a vibrating beam technique. Discussed are examples of decreased apparent modulus after high temperature creep and their implications for degree of fiber matrix interfacial debonding. Keywords: Carbon-carbon composites, Carbon fibers, Carbon yarns, Creep, Elastic modulus, High temperature creep, Microstructure, Resistivity, Vibrating beam.
