NICALON CERAMIC FIBER - COI Ceramics, Inc.

1 REV 1/06 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. Our San Diego, California facilitymanufactures CMC s while our Salt Lake City, Utahfacility serves as a worldwide FIBER distribution andtechnical support center. For more information onceramic FIBER capabilities and cost, contact ourtechnical staff at (801) 251-8111 or , (801) 251-8049or browse the web at Sendwritten requests to 7812 West 4100 South, Magna,Utah DESCRIPTIONNICALON CERAMIC FIBER is a multi-filament siliconcarbide-type FIBER manufactured by Nippon CarbonCo., Ltd. of Japan. The FIBER is homogeneouslycomposed of ultra-fine beta-SiC crystallites and anamorphous mixture of silicon, carbon, and FIBER has excellent strength and modulusproperties for CERAMIC fibers, and retains its propertiesat high temperatures.

2 NICALON is highly resistantto oxidation and chemical is available in a wide variety of electricalgrades, product forms, and surface treatment options,depending on the intended use. Typical propertiesare shown in Table CERAMIC FIBER can be used as areinforcement for plastic, CERAMIC , and metal matrixcomposites to produce high performance compositematerials. Surface treatments are normallyrecommended to facilitate processing and maximizecomposite can also be used to form fibrous productssuch as high temperature insulation, filters, etc. Itsresistance to chemical attack allows it to be used inharsh CERAMIC FIBER is available in two primarygrades, differentiated by electrical properties. Otherelectrical grades, such as low volume resistivity arealso available. Contact COI Ceramics to discussspecific Grade (CG) NICALON The standard grade of the NICALON product line;offers the optimum mechanical properties and high-temp performance for most Grade NICALON A low dielectric (high volume resistivity ) FIBER that isdesigned to offer an optimum balance of mechanicaland electrical properties in dielectric FORMSNICALON CERAMIC FIBER is available in severalphysical forms and with several surface treatmentoptions, to offer the maximum application FiberSupplied as multi-filament tow, spooled on 3 inch IDbobbins to 500 meters in length (100 grams inweight).

TO USEP olymer Matrix CompositesNICALON family of products is suitable forincorporation into standard resin prepreg, usingconventional prepreg techniques.

4 Unidirectional ororiented prepreg can be produced using continuousfiber, or woven cloth, respectively. Special FIBER surfacetreatments (see Table 3) are normally recommendedto maximize FIBER property translation into thecomposite and to afford superior retention ofcomposite properties under hot-wet conditions. Resinsystems can include the entire line of thermosets Matrix CompositesNICALON can be incorporated as the reinforcingphase for a variety of CERAMIC composites. StandardCMC processing techniques, such as sol-gel, chemicalvapor infitration, melt infiltration or polymer infiltrationcan be used, depending on the users needs andcapabilities. Candidate matrix materials include siliconcarbide, silicon nitride, alumina, glasses, and surface treatments are generally removed beforemaking CMC s, such as by heating to 600C for 30minutes. FIBER interface coatings, such as BN, arerecommended to achieve optimum CMC specific grade of NICALON and the specificprocessing technique is best determined by the Matrix CompositesChopped, woven, or continuous NICALON ceramicfiber can serve as a reinforcing phase in MMC s.

5 Thespecific grade of NICALON and the specific processingtechnique is best determined by the , Braiding, and CoatingAs a textile grade yarn, NICALON can be readilyincorporated into a large variety of woven tapes,braides, etc. Specialty interface coatings such as BN(often required for optimum CMC mechanicalproperties) may be applied to the tow or cloth.
