초록 ▼

A method of fabricating a carbon fiber-reinforced article includes providing carbon fibers that have surfaces that include an initial interfacial bonding strength capacity with respect to bonding with boron nitride. The surfaces are then modified to reduce the initial interfacial bonding strength capacity. A layer of boron nitride is then deposited on the modified surfaces and the carbon fibers are then embedded in a ceramic matrix. A carbon fiber-reinforced article includes the carbon fibers, the layer of boron nitride on the surfaces of the carbon fibers, and the ceramic matrix. The article exhibits non-brittle fracture.

1. A method of fabricating a carbon fiber-reinforced article, the method comprising: providing a plurality of carbon fibers, the plurality of carbon fibers including surfaces;ordering microstructural stacking faults in a graphitic microstructure of the surfaces of the plurality of carbon fibers;depositing a layer of boron nitride on the surfaces;depositing a silicon-containing layer on the layer of boron nitride: andembedding the plurality of carbon fibers in a ceramic matrix to provide a carbon fiber-reinforced article. 2. The method as recited in claim 1, wherein the ceramic matrix is silicon carbide. 3. The method as recited in claim 1, wherein the surfaces of the plurality of carbon fibers are free of any ceramic coating prior to the depositing of the layer of boron nitride. 4. The method as recited in claim 1, wherein the plurality of carbon fibers are as-received fibers. 5. The method as recited in claim 1, including depositing the layer of boron nitride by chemical vapor deposition. 6. The method as recited in claim 1, wherein the layer of boron nitride is in contact with the surfaces of the plurality of carbon fibers, and the ceramic matrix is silicon carbide that is in contact with the layer of boron nitride. 7. The method as recited in claim 1, wherein the layer of boron nitride deposited on the surfaces consists of boron nitride. 8. The method as recited in claim 1, wherein the ceramic matrix is predominantly silicon carbide. 9. The method as recited in claim 1, wherein the depositing of the layer of boron nitride is conducted after the ordering, free of any other surface modifications to the plurality of carbon fibers. 10. A method of fabricating an oxidation-resistant carbon fiber, the method comprising: providing at least one carbon fiber, the at least one carbon fiber including an exposed surface;ordering microstructural stacking faults in a graphitic microstructure of the exposed surface; anddepositing a layer of boron nitride on the exposed surface, the layer of boron nitride having a thickness of 50-150 nanometers. 11. The method as recited in claim 1, wherein the ordering is concluded prior to the depositing of the layer of boron nitride. 12. The method as recited in claim 1, wherein the carbon fiber-reinforced article exhibits non-brittle fracture. 13. The method as recited in claim 1, wherein the layer of boron nitride has a thickness of 50-150 nanometers. 14. The method as recited in claim 1, wherein the silicon-containing layer is silicon nitride. 15. The method as recited in claim 10, further comprising depositing a silicon-containing layer on the layer of boron nitride. 16. The method as recited in claim 15, wherein the silicon-containing layer is silicon nitride.
