Claims
- 1. A carbon—carbon joint having a joint thickness greater than 25 micrometers and up to about 2500 micrometers, said joint having an interlayer, of which the thermal expansion mismatch to carbon—carbon is minimized, said interlayer having a composition of a metal-rich, non-stoichiometric mixture of reactive-bonding compounds.
- 2. The joint of claim 1, wherein said composition comprises a mixture of fine particle-sized refractory carbides.
- 3. The joint of claim 2, wherein said refractory carbides comprise metallic ingredients that are selected from the group consisting of W, Ti, Si, Ta, Nb, Zr, Hf, V, Cr and Mo.
- 4. The joint of claim 2, further comprising a filler material composed of at least one refractory compound selected from the group consisting of borides, carbides, silicides, and nitrides.
- 5. A carbon—carbon joint having a thickness ranging from about 25 and up to about 2500 micrometers and a dimension matching a faying area of the carbon—carbon parts to be joined, said joint comprised of a composition of refractory carbides that have a particle size of up to about 100 micrometers and are reactive-bonding compounds, said composition having a mixture that is metal rich and nonstoichiometric.
- 6. The joint of claim 5, wherein said refractory carbides comprise metallic ingredients selected from the group consisting of W, Ti, Si, Ta, Nb, Zr, Hf, V, Cr and Mo.
- 7. The joint of claim 5, wherein said composition further comprises a filler material composed of at least one refractory compound selected from the group consisting of borides, carbides, silicides, and nitrides.
- 8. A carbon—carbon joint layer comprising a composition of a metal-rich, nonstoichiometric mixture of reactive-bonding compounds of metals and carbon, said metals and carbon having particles sizes up to about 100 micrometers and forming refractory carbides.
- 9. The joint layer of claim 8, wherein said composition further comprises carbon fibers up to about 5 mm in length.
- 10. The joint layer of claim 8, wherein said composition further comprises refractory compounds as filler materials.
- 11. The joint layer of claim 8, wherein said layer is about 25 and up to about 2500 micrometers thick.
- 12. The joint layer of claim 8, wherein said composition further comprises silicides.
- 13. The joint of claim 5, wherein said joint is further characterized by a minimized thermal expansion mismatch to said carbon-carbon parts.
