- 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
