Summary
The stress-rupture and stress-relaxation behavior of carbon fiber-reinforced melt-infiltrated silicon carbide composites was investigated in ambient air at 1000¿̐ưC. It was found that the compliance of the material increases continuously with time when subjected either to a constant composite stress or strain in air at 1000¿̐ưC. The changes in compliance are explained based on the oxidation of the fiber coating, and on the oxidation, loss of cross-sectional area and rupture of the reinforcing fibers. In the case of stress-rupture, the load previously carried by failed fibers is redistributed to their surviving neighboring fibers inducing further fiber failure. During stress-relaxation, fiber failure is reflected directly on the reduction of the load carried by the composite.
