ABSTRACT:
A high temperature cushion for a low ductility member or article, such as of a ceramic material, comprises a flexible, fibrous core of a resilient, refractory material, and a metal foil of a high temperature material covering the core. The foil has ductility sufficient to be formed about the core, the core and foil being further characterized by the ability to withstand a temperature of at least about 1,000.degree. F. (about 540.degree. C.) Forms of such a cushion include an annular bushing and various shaped holders and interface members. Such a cushion can be included as a part of a high temperature operating article which comprises metal portions functioning as backing or holding members, a low ductility article or member such as of a ceramic material, a high temperature cushion interfacing between the metal portions and the member, and a securing member mechanically joining the metal portion with the low ductility member.
