Silicon carbide fibers

This article is about loose or woven silicon carbide filament. For the rigid composite material made from silicon carbide fiber used in aerospace and other applications, see Ceramic matrix composite.

Silicon carbide fibers are fibers ranging from 5[1] to 150[2] micrometres in diameter and composed primarily of silicon carbide molecules. Depending on manufacturing process, they may have some excess silicon or carbon, or have a small amount of oxygen. Relative to organic fibers and some ceramic fibers, silicon carbide fibers have high stiffness,[2] high tensile strength,[2] low weight, high chemical resistance, high temperature tolerance[dubious – discuss] and low thermal expansion. (refs) These properties have made silicon carbide fiber the choice for hot section components in the next generation of gas turbines, e.g. the LEAP engine[3] from GE (General Electric).[4]
