Several studies have been completed on silicon carbide fiber-reinforced silicon carbide (SiC{sub f}/SiC) composites produced with carbon-coated fibres having a 0/90{degree} architecture. Yet, while mechanical property measurements have been made at temperatures up to 1,473K in air and argon high-temperature creep tests have been carried out only under protective atmospheres. To clarify the creep behavior patterns displayed by continuous-fiber-reinforced CMCs, while simultaneously providing information relevant to aeroengine turbine design, the tensile creep and creep fracture properties of a 0/90{degree} SiC{sub f}/SiC composite have been determined over a stress range giving creep rupture lives up to approximately 2,000 hours in air at 1,573K.
