Nicalon™ Silicon Carbide Fiber
Nicalon™ is a Silicon Carbide (SiC) fiber that possesses high strength, corrosion and heat resistances. These fibers bring improvements to ceramics, polymer, and metal matrix composites (CMC, PMC, MMC). Nicalon™ has been used and tested in the Aerospace Industry. New innovations continue to be investigated by other industries as well.
