Tensile strength of carboncarbon composites (1) effect

The tensile fracture stress and strain of carbon fiberreinforced carbon matrix composites (CCs) were examined as functions of the bulk density. When the density increased, the interfacial strength of the CCs monotonically increased, and the tensile fracture strain decreased. In contrast, the tensile fracture stress was improved and degraded in the regions of density lower and higher than 1
