Abstract
Official abstract text for this publication.
Disclosed is a coating layer-bonded continuous ceramic fiber formed from a continuous ceramic fiber having a coating layer of a metal compound with a thickness of 50 nm or less on the surface. Also disclosed is a ceramic matrix composite material having the above-described coating layer-bonded continuous ceramic fiber.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coating layer-bonded continuous ceramic fiber comprising a continuous ceramic fiber having a coating layer of a metal compound with a thickness of 7 nm or less on the surface. 2. The coating layer-bonded continuous ceramic fiber according to claim 1 , wherein the metal compound is at least any one of a zirconium compound or a lanthanum compound. 3. The coating layer-bonded continuous ceramic fiber according to claim 1 , wherein the metal compound is zirconia or lanthanum oxide. 4. The coating layer-bonded continuous ceramic fiber according to claim 1 , wherein the continuous ceramic fiber is at least any one of a continuous alumina fiber or a continuous mullite fiber. 5. A ceramic matrix composite material comprising the coating layer-bonded continuous ceramic fiber according to claim 1 . 6. The ceramic matrix composite material according to claim 5 , wherein an interfacial strength is 10 MPa or less. 7. A method for producing the coating layer-bonded continuous ceramic fiber according to claim 1 , the method comprising: impregnating a continuous ceramic fiber with a solution including a metal acetylacetonate complex; and heat-treating the continuous ceramic fiber after impregnation. 8. A method for producing a ceramic matrix composite material, the method comprising compositing the coating layer-bonded continuous ceramic fiber according to claim 1 with a ceramic matrix.
