Abstract
Nonmetallic high-temperature material, such as graphite, CFC or SiC, or components produced from these materials, are joined using the two-stage process. First the structural components are canned and the canning foil is tightly pressed onto the surface contour of the structural components. Then the components are joined to a composite component by forming a material-to-material bond between the metal canning foils. This widens the hitherto highly restricted field of technical application for materials of this type.
Claims22
A method of producing a composite component, which comprises:
- providing at least one non-metallic structural component of high-temperature material and at least one further structural component of high-temperature material;
- applying a gastight metal foil with a thickness from 10 to 2000 μm to the non-metallic structural component by way of a canning process followed by at least one of die pressing and isostatic pressing, to form at least one canned component;
- and
- subsequently joining at least two of said structural components at joining surfaces thereof, with a process selected from the group consisting of brazing, welding, and common canning in a metal foil with a material-to-material bond effected by hot pressing or hot isostatic pressing, to form the composite component.

A composite component, comprising:
- a plurality of structural components including at least one structural component of non-metallic high-temperature material;
- a gastight metal foil with a thickness from 10 to 2000 μm tightly encasing said structural component of non-metallic high-temperature material;
- and
- said plurality of structural components being joined at joining surfaces thereof with material-to-material bonding between said metal foil and an adjoining said joining surface.
