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. The standard grade of the Nicalon™ product line; offers the optimum mechanical properties and high temperature performance for most applications.Information from COI Ceramics, Inc.
