Ceramic Matrix Examples

Both the matrix and the fibers can consist of any ceramic material whereby carbon and carbon fibers can also be considered a ceramic material.

Ceramic matrix examples.

13th annual conference on composites and advanced ceramic materials cocoa beach fl usa january 1989. Cmcs are designed to overcome the main drawback of monolithic ceramics namely their brittleness. Example uses turbines furnaces brake disks and machine parts such as slide bearings. 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.

And wada s sic matrix composites reinforced with internally synthesized tib 2. In some cases the same kind of ceramic is used for both parts of the structure and additional secondary fibers may also be included. Ceramic matrix composites cmcs are a special type of composite material in which both the reinforcement refractory fibers and matrix material are ceramics. A similar effect can be achieved by adding a reducible compound containing the desired transition metal alloying addition.

For example adding nio or nial 2 o 4 to a preform in order to dope the growth alloy with ni 45. 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. Ceramic matrix composites may also be designed for high tensile strength flextual strength and extreme durability. Ceramic matrix composites cmcs are a subgroup of composite material as well as a subgroup of technical ceramic.

Ceramic matrix composites cmcs generally consist of ceramic fibers or whiskers in a ceramic matrix. They consist of ceramic fibers embedded in a ceramic matrix thus forming a ceramic fiber reinforced ceramic cfrc material.
