Fibers and filaments consist of bulk, chopped fibers or strands and continuous monofilaments of materials and are used in reinforcing composites as well as other specialized electrical and thermal applications

Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members.

Cylindrical ceramic fiber heaters consist of an iron-chrome-aluminum (ICA) heating element and a thick layer of ceramic fiber insulation within a cylinder-shaped housing

Flat ceramic fiber heaters consist of an iron-chrome-aluminum (ICA) heating element and a thick layer of ceramic fiber insulation within a non-curved housing

Aramid fiber and fabrics consists of bulk, chopped fibers, continuous strands or woven cloth forms of aromatic polyamide thermoplastic for reinforcing polymer matrix composites and other applications

Specialty optical fiber is modified, usually by doping, for a specialized function.

Carbon fiber and carbon fiber cloth consist of bulk, chopped fibers, continuous strands or woven cloth forms of carbon or graphite.
