SiC/SiC Composites for 1200°C and Above

摘要: The successful replacement of metal alloys by ceramic matrix composites (CMC) in high-temperature engine components will require the development constituent materials and processes that can provide CMC systems with enhanced thermal capability along key thermostructural properties required for long-term component service. This chapter presents information concerning five silicon carbide (SiC) fiber-reinforced SiC composite recently developed NASA operate under mechanical loading oxidizing conditions hundreds hours at 1204, 1315, 1427°C, temperatures well above current capability. advanced stems large part from specific NASA-developed significantly improve creeprupture environmental resistance fiber as conductivity, creep resistance, intrinsic stability matrices.
