ABSTRACT
Silicon carbide based ceramics matrix composites (CMCs) seek to replace nickel superalloys in gas turbine components due to their comparatively
low density and high strength at elevated temperatures, however, the introduction of these new composite materials can only be achieved after failure mechanisms are properly understood. Harsh combustion environments are known to decrease fatigue life of these
composite materials, though the effect of oxidation on mechanical properties is still not fully understood, leading to unpredictable failure of components. A review of the current literature relating to static fatigue of siliconized silicon carbide is presented
with emphasis given to oxidation mechanisms within the composite system. Gaps within literature are addressed and a plan for continued research into the effects of oxidation on static fatigue behavior in siliconized silicon carbide is proposed.
