Abstract
A seal for use at high temperatures in an interface between a ceramic component and a metal component has a multi-layer construction arranged so that the seal expands disproportionately more in cross-section than in elongation at increasing operating temperatures. The seal comprises a central core made up of a bundle of elongate ceramic fibers surrounded by a layer of braided metal wire and an outer sheath of braided ceramic fiber. The seal may be formed as an O-ring.
