Summary

A novel ceramic matrix composite using Si-Ti-C-O fiber and inorganic materials, which can be produced from polytitanocarbosilane, was successfully obtained by the hot-pressing method at 1950°C because Si-Ti-C-O fiber kept a fibrous shape up to 2000°C. Another type of the ceramic matrix composite could be also fabricated by the use of only Si-Ti-C-O fiber under the same conditions. In the cross section of the composite produced from only Si-Ti-C-O fiber, the fiber was found to be distorted from a cylindrical shape to a hexagonal columnar shape in order to get the closest packing. These new types of ceramic matrix composites, which have a bending strength of 200-500 MPa, can be expected to have high heat-resistance and excellent fracture toughness at above 1600°C in air.
