Ceramic Matric Composities

Ceramic matrix composites cmc are generally made from ceramic fibres or whiskers embedded in a ceramic matrix.

Ceramic matric composities.

Ceramics consist of alumina silica zirconia and other elements refined from fine earth and sand or of synthetic materials such as silicon nitride or silicon carbide. 1650 f 900 c structural applications solvent free ceramic matrix. The materials are manufactured in net shape braided and multi directionally reinforced billet configurations to suit complex designs in a variety of propulsion and thermal protection applications. They consist of ceramic fibres embedded in a ceramic matrix forming a ceramic fibre reinforced material.

350 f 177 c initial 2000 f freestanding fire. 13th annual conference on composites and advanced ceramic materials cocoa beach fl usa january 1989. To provide a comprehensive overview of ceramic matrix composite technology outlining the history applications benefits ceramic composite systems methods of fabrication quality control and supportability. Ceramic matrix composites cmcs are a special type of composite material in which both the reinforcement refractory fibers and matrix material are ceramics.

And wada s sic matrix composites reinforced with internally synthesized tib 2. To be published in the proceedings. Ceramic matrix composites cmcs provide high temperature oxidation stability relative to metals and enhanced toughness relative to monolithic ceramics. Both the matrix and the fibers can consist of any ceramic material whereby carbon and carbon fibers can also be considered a ceramic material.

They consist of ceramic fibers embedded in a ceramic matrix. Aircraft engine components ducting oil gas tubing advanced energy motorsports. For the latter applications ceramic matrix composites cmcs are seeing increasing use although the technology for cmcs is less mature than that for pmcs. Ceramic matrix composites cmcs are a subgroup of composite materials as well as a subgroup of ceramics.

To specify the methods and procedures to be used in the characterization of ceramic matrix composites and their constituents. Fmi ceramic matrix composites cmcs are designed to replace refractory metals and other materials in high temperature applications where erosion or deformations are a concern. In some cases the same kind of ceramic is used for both parts of the structure and additional secondary fibers may also be included.
