Sylramic™ SiC Fiber products. is manufactured at the COIC San Diego facility, which also specializes in the manufacture of both oxide and nonoxide CMC products. The COIC Salt Lake City facility serves as the worldwide distribution and customer service center for ceramic fiber reinforcement products. The use of two facilities ensures the confidentiality of the customer-specific fiber and CMC business areas. COI Ceramics, Inc. (COIC) is the leading supplier of high temperature Sylramic™ and Nicalon™ SiC fibers. COIC has also been manufacturing and supplying ceramic matrix composites (CMCs) that incorporate these fibers since 1999.

- Uses
Sylramic™ SiC Fiber is typically used as a reinforcement in various materials including ceramic, plastic, and metal matrix composites. These products are used in severe environments such as aircraft and land-based turbine engines, hypersonic vehicles, thermal protection systems, and components in chemical manufacturing equipment. The use of Sylramic™ SiC Fiber provides increased strength, toughness, chemical resistance, and high temperature creep resistance of various Sylramic™ SiC Fiber products
Properties
- Typical Properties
- Special Properties
Sylramic™ SiC Fiber has excellent room temperature strength and stiffness. The fiber has excellent creep resistance, maintaining strength and stiffness for extended times at extremely high temperatures (> 1400°C / 2252°F). These fiber properties are due to its chemical composition, crystalline structure, small crystal size, and very low oxygen content. This also allows it to have excellent wear and corrosion resistance capability. See Table 1 for typical properties and composition information. Sylramic™ SiC Fiber overcomes the disadvantages of other materials. Oxide fibers and superalloys may lose their mechanical properties above 800°C (1472°F). SiCO fibers lose mechanical properties above 1000°C (1832°F), while amorphous SiC fibers lose mechanical properties above 1200°C (2192°F). Larger diameter (100 µm), crystalline SiC fibers are not easily woven
