Due to exhibiting high temperature capabilities, low density, and resistance to oxidation and corrosion, SiC/SiC CMCs are largely used in aerospace applications.
The implementation of SiC/SiC ceramic matrix components will improve aircraft and space vehicle performance and fuel efficiency, reducing additional harm to the environment in a cost-effective manner.
Additional applications of SiC/SiC CMCs include combustion and turbine section components of aero-propulsion and land-based gas turbine engines, thermal protection systems, thruster nozzles, reusable rocket nozzles, and turbopump components for space vehicles.
With the development and implementation of future SiC/SiC CMCs, the SiC fiber creep and rupture properties must be examined.
Defects such as grain size, impurities, porosity, and surface toughness all contribute to SiC fiber creep and rupture.
