- 17. The method of claim 16, wherein the barrier layer comprises a material selected from the group consisting of molybdenum, tungsten, ceramic, and combinations thereof.
- 18. The method of claim 16, wherein the assembly is heated between about 2,150° F. to about 2,350° F.
- 19. The method of claim 1, wherein the assembly is heated between about 70% to about 90% of the melting point of the plurality of mesh layers.
- 20. The method of claim 1, wherein the assembly is heated in a heating atmosphere selected from the group consisting of a gas, a gas mixture, a vacuum, and combinations thereof.
- 21. The method of claim 1, wherein the assembly is heated in a heating atmosphere having a gas selected from the group consisting of hydrogen, nitrogen, and combinations thereof.
- 22. The method of claim 1, wherein the central core comprises one or more perforations.
- 23. A method of manufacturing a sintered mesh laminate, comprising:
surrounding a first barrier layer around a central core; wrapping a plurality of mesh layers and a second barrier layer around the central core; disposing a cover around the plurality of mesh layers and the second barrier layer, wherein the first and second barrier layers comprise a material having a higher melting point than the mesh layers; and heating the cover and the plurality of mesh layers.
- 24. The method of claim 23, wherein the central core is expanded upon heating.
- 25. The method of claim 24, wherein the expansion exerts a pressure against the plurality of mesh layers.
- 26. The method of claim 25, wherein the plurality of mesh layers is at least partially fused together.
- 27. The method of claim 23, wherein the cover and the spool assembly are heated in a heating atmosphere selected from the group consisting of a gas, a gas mixture, a vacuum, and combinations thereof.
- 28. The method of claim 23, wherein the cover and the plurality of mesh layers are heated between about 2,150° F. to about 2,350° F.
- 29. The method of claim 23, wherein the cover and the plurality of mesh layers are heated between about 50% to about 95% of the melting point of the plurality of mesh layers.
- 30. The method of claim 23, wherein the cover and the plurality of mesh layers are heated between about 70% to about 90% of the melting point of the plurality of mesh layers.
- 31. An apparatus for manufacturing a mesh laminate, comprising:
a central core; a barrier layer and one or more mesh layers surrounding the central core; and a restraining member for retaining the barrier layer and the one or more mesh layers around the central core.
- 32. The apparatus of claim 31, wherein the barrier layer includes a material having a higher melting point than the one or more mesh layers
- 33. The apparatus of claim 31, further comprising a second barrier layer disposed around the central core.
- 34. The apparatus of claim 31, wherein the restraining member comprises a cover having an inner diameter that is smaller than an outer diameter of the one or more mesh layers surrounding the central core.
- 35. The apparatus of claim 31, wherein the restraining member comprises a material having a relatively low coefficient of thermal expansion.
- 36. The apparatus of claim 31, wherein the central core comprises a material having a relatively high coefficient of thermal expansion.
- 37. The apparatus of claim 31, wherein central core comprises one or more perforations.
- 38. The apparatus of claim 31, wherein the barrier layer comprises a material selected from the group consisting of molybdenum, tungsten, ceramic, and combinations thereof.
