Fiber Reinforced Ceramic Matrix

Continuous fiber reinforced ceramic matrix composites cmcs are currently considered for applications as structural materials in both aerospace and other industries since they retain the advantages of ceramics while providing an enhanced damage tolerance generally ceramic matrix composites are fabricated at high temperature i e.

The carbon fibers have the attractive properties such as low density high tensile modulus and strength low thermal expansion coefficient high thermal conductivity and so on which is often compounded with a matrix such as resin metal or ceramic to form a structural composite currently the fiber reinforced composites widely applied in many fields. This occurs in the presence of a wi as the crack resistance of the fiber matrix interface is low. Some gaseous precursors used in the cvi method and the corresponding ceramic yields are summarized in table 1 sayir incorporated an hfc matrix into a carbon fiber fabric by the cvi process tang et al.

Both the matrix and the fibers can consist of any ceramic material whereby carbon and carbon fibers can also be considered a ceramic material. Continuous fiber reinforced sic matrix composites as the most common ceramic matrix composites cmcs have been extensively studied in the last two decades due to low density high strength at. 100 in this method a nano zrb 2 sic slurry was brushed onto subdivided pyc coated c f to create fiber reinforced ceramic plates which were stacked together along the fiber direction or in a 0 90 layup. 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.

Typically 900 1100 c of the chemical. Sic sic matrix composite is a particular type of ceramic matrix composite cmc which have been accumulating interest mainly as high temperature materials for use in applications such as gas turbines as an alternative to metallic alloys cmcs are generally a system of materials that are made up of ceramic fibers or particles that lie in a ceramic matrix phase. Ceramic such as oxides nitrides silicides and borides are the continuous part of the composite in which the metal nanofiber or the ceramic nanofiber is reinforced to achieve a higher toughness of the composite.

Carbon fiber reinforced sic c f sic ceramic matrix composites have attracted great attentions for the improved strength and fracture resistance with the addition of high strength and modulus fibers 2 3.
