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.
Certain amount of elongation in cmc improves the tensile and compressive property.
Properties of cmc tensile compressive behaviour no sudden failure in cmc as like in ceramics.
Large grains of one phase embedded in a nanocrystalline matrix of a second phase fig.
Material having ceramic as a matrix material in composites called as ceramic matrix composite cmc.
Grains of one phase separated by grain boundaries of a second phase fig.
Fracture toughness it limits to ceramics but for cmc s fracture.
Ceramic matrix composites cmcs may be processed via conventional layup and curing techniques while only requiring a free standing high temperature sinter cycle to prepare them for high temperature use.
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 in design is the property of its rightful owner.
Ceramic matrix composites cmcs generally consist of ceramic fibers or whiskers in a ceramic matrix.
The microstructure can have equiaxed nanoscale grains of different phases fig.
Next generation ceramic matrix composites cmcs are being developed for future applications such as turbine blades top left these may use new technologies such as water like polymers that can be processed into 1700 c capable low density ceramics bottom or nanofibers grown onto silicon carbide sic reinforcing fibers for increased toughness top right.
