A method of bonding at least two members having different coefficients of thermal expansion is disclosed, wherein an edge of a bonding interface between the members is positioned in a tapered portion, thereby bridging one member having a smaller coefficient of thermal expansion and another having a larger coefficient of thermal expansion. A bonded composite article comprising such bonded members having the different coefficients of thermal expansion is also disclosed.
