An apparatus for attaching two components having different coefficients of thermal expansion includes a mounting member configured to be movably coupled relative to a first component, an attachment member opposite the mounting member and configured to be attached to a second component, and at least one support post interconnecting the mounting member and the attachment member. The apparatus also includes a backer plate including at least one aperture configured to permit at least one fastener to pass therethrough and pass through the second component and through at least one aperture in the attachment member to secure the backer plate and the attachment member to the second component and to attach the second component to the first component. The diameter of the aperture of the backer plate restricts the head of the fastener from passing through the aperture of the backer plate.

Systems and methods for attachment of materials having different thermal expansion coefficients

Systems and methods for attaching a protective liner to a an aircraft engine component having a different coefficient of thermal expansion in comparison to the protective liner include a mounting member configured to be mounted to the aircraft engine component and an attachment member configured to be attached to the protective liner. The mounting member and the attachment member are coupled to each other such that a portion of the mounting member is received within a portion of the attachment member and such that the mounting member is permitted to move with both radial and rotational freedom relative to the attachment member.
