Sic/sic creep
WebApr 15, 1996 · In SiC/SiC composites, the matrix has greater creep resistance than the fibers. The consequent fiber deformation has been shown to transfer sufficient stress … Silicon carbide (SiC) ceramic matrix composites (CMCs) are a specific application of engineering ceramic materials used to enhance aerospace applications such as turbine engine components and thermal protection systems. Due to exhibiting high temperature capabilities, low density, and resistance to oxidation and corrosion, SiC/SiC CMCs are largely used in aerospace applications. The use of SiC/SiC CMCs on rotating engine components reduce the complexity of design and e…
