Ceramic Matrix Examples

Ceramic matrix composites cmcs generally consist of ceramic fibers or whiskers in a ceramic matrix.

Ceramic matrix examples.

They are referred to as inverse composites which is to say that the failure strain of the matrix is lower than the failure strain of the fibers whereas it is the reverse in most polymer or metal. Ceramic matrix composites cmcs are a subgroup of composite material as well as a subgroup of technical ceramic. Both the matrix and the fibers can consist of any ceramic material whereby carbon and carbon fibers can also be considered a ceramic material. For example as noted the presence of transition metals in the alloy used to grow an al 2 o 3 matrix composite results in a refinement in the matrix microstructure.

In some cases the same kind of ceramic is used for both parts of the structure and additional secondary fibers may also be included. 13th annual conference on composites and advanced ceramic materials cocoa beach fl usa january 1989. Example uses turbines furnaces brake disks and machine parts such as slide bearings. Ceramic matrix composites cmcs are a subgroup of composite materials as well as a subgroup of ceramics they consist of ceramic fibers embedded in a ceramic matrix.

For example adding nio or nial 2 o 4 to a preform in order to dope the growth alloy with ni 45. Ceramic matrix composites cmcs are a special type of composite material in which both the reinforcement refractory fibers and matrix material are ceramics. To be published in the proceedings. And wada s sic matrix composites reinforced with internally synthesized tib 2.

Ceramic matrix composite 1. They consist of ceramic fibers embedded in a ceramic matrix thus forming a ceramic fiber reinforced ceramic cfrc material.
