SiC fibers see increasing use in high-temperature applications

GE replaces nickel alloys with SiC fiber-based composites for jetliner engine parts

Ceramics made with SiC fibers are two-thirds lighter than nickel-based superalloys.

TOKYO -- Silicon carbide (SiC) fibers are emerging as an alternative to traditional, nickel-based superalloys for components requiring high heat resistance, such as aircraft engine parts.

Ceramic matrix composites (CMCs) made with SiC fibers are twice as strong and 20% more heat resistant than the alloys despite being two-thirds lighter.
