HI-NICALON CERAMIC FIBER

1 CERAMIC composites. It can also be used as areinforcement for plastic, and metal matrix treatments are normally recommended tofacilitate processing and maximize compositeproperties. The FIBER can also be used to form fibrousproducts such as high temperature insulation, filters,etc. Its resistance to chemical attack allows it to beused in harsh environments. Typical FIBER propertiesare shown in Table FORMSHI- nicalon CERAMIC FIBER is available in severalphysical forms to offer the user application FIBER is coated with polyvinyl alcohol (PVA) sizingfor improved FiberSupplied as multi-filament tow, spooled on 3 inch IDbobbins to 500 meters in length (100 grams inweight).

2 Also available in random lengths at a ClothAvailable as Plain Weave, 5HS Weave or 8HS Weave,as identified in Table 2, HI-NICALON cloth istypically supplied as 1 meter-wide continuous rolls ofspecific lengths. Other widths, weave or braid stylescan be made available. Contact COI Ceramics todiscuss specific FiberAvailable as 1-mm length chopped multi-filamenttow. Longer lengths also available. Contact COIC eramics to discuss specific TO USEC eramic Matrix CompositesHI- nicalon FIBER can be incorporated as thereinforcement for a variety of CERAMIC CMC processing techniques, such as sol-gel, chemical vapor infiltration, melt infiltration, orpolymer infiltration can be used, depending on theuser s needs and capabilities.

3 Candidate matrixmaterials include silicon carbide, silicon nitride,alumina, glasses, and others. FIBER surface treatmentsare generally removed before making CMC s, suchas by heating to 600C for 30 minutes. FIBER interfacecoatings, such as BN, are generally applied to thefiber to achieve optimum CMC properties. The specificfiber type and the specific CMC processing techniqueis best determined by the 1/06HI-NICALONTMCERAMIC FIBERCOI Ceramics, Inc. (COIC) is a leading supplier ofceramic reinforcements and CERAMIC matrixcomposites (CMC). COIC began operations in 1999and employees a highly technical staff with extensiveexperience and knowledge in high performanceceramics.

(NCK) of Japan. NCK is known worldwide asthe leading manufacturer and innovator of multi-filament silicon carbide-type fibers. HI-NICALON ismanufactured near-oxygen-free using electron-beamcuring.

5 The FIBER is homogeneously composed of ultra-fine beta-SiC crystallites and carbon. The FIBER hasexcellent strength and modulus properties, and hashigher thermal stability than nicalon . HI-NICALON is highly resistant to oxidation andchemical attack and is available in a variety of productforms, depending on the intended CERAMIC FIBER is primarily designedto be used as reinforcements for high temperatureCOI Ceramics, Incorporated 7812 West 4100 South Magna, Utah 84044 Tel: or Fax: 8 01.
