COI Ceramics Nicalon™ HRV SiCO Ceramic Fiber
Categories: Ceramic; Carbide

Material Notes: Description: The fiber is homogeneously composed of ultra-fine beta-SiC crystallites and an amorphous mixture of silicon, carbon, and oxygen. The fiber has excellent strength and modulus properties for ceramic fibers, and retains its properties at high temperatures. Nicalon™ is highly resistant to oxidation and chemical attack.

Product Forms:
Continuous Fiber: Supplied as multi-filament tow, spooled on 3 inch ID bobbins to 500 meters in length (100 grams in weight). Also available in random lengths at a reduced price.
Woven Cloth: Available in three weave styles as shown in Table 2. Woven cloth is typically supplied as 1-meter-wide continuous rolls of specific lengths. Other weave or braid styles can be made available.
Chopped Fiber: Available of 1-mm length chopped multi-filament tow. Longer lengths also available. Packaged as 3 kg containers.
Felt / Mat: Random lengths of Nicalon™ ceramic fiber in a PVA binder. Customizable areal weights, shapes and sizes.

Uses: Nicalon™ ceramic fiber can be used as a reinforcement for plastic, ceramic, and metal matrix composites to produce high performance composite materials. Surface treatments are normally recommended to facilitate processing and maximize composite properties Nicalon™ can also be used to form fibrous products such as high temperature insulation, filters, etc. Its resistance to chemical attack allows it to be used in harsh environments. A low dielectric (high volume resistivity) fiber that is designed to offer an optimum balance of mechanical and electrical properties in dielectric structures.
