Abstract

The mechanical properties and failure behavior of a tightly woven carbon-carbon composite were investigated and correlated with microstructural features. The analysis of fracture surfaces and microstructural characterization were accomplished using scanning electron microscopy. The tensile strength, flexural strength, fracture toughness, and failure mechanisms of this composite were determined at elevated temperatures. Strength and fracture toughness of the composite increased in argon, but decreased in air as the temperature increased. Microscopic observations of the fracture surfaces of the broken specimens revealed that the composite failed in a tension/shear mixed mode rather than in pure tension.
