Ceramic matrix examples.

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. Ceramic matrix composites cmcs are a special type of composite material in which both the reinforcement refractory fibers and matrix material are ceramics. 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 cmcs are a subgroup of composite material as well as a subgroup of technical ceramic. They consist of ceramic fibers embedded in a ceramic matrix thus forming a ceramic fiber reinforced ceramic cfrc material. 13th annual conference on composites and advanced ceramic materials cocoa beach fl usa january 1989.

A similar effect can be achieved by adding a reducible compound containing the desired transition metal alloying addition. Ceramic matrix composite 1. 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 composites may also be designed for high tensile strength flextual strength and extreme durability.
