Abstract

A method of joining metals to a ceramic material such as a ceramic matrix composite is provided which utilizes a compliant interlayer having a coefficient of thermal expansion between the coefficient of thermal expansion of the metal and that of the ceramic matrix composite. The compliant interlayer is bonded to the metal, and the ceramic matrix composite is then bonded to the bonded interlayer/metal. The method results in a high strength joint between a metal having a high coefficient of thermal expansion and a ceramic material having a low coefficient of thermal expansion.
