A ceramic component retention system includes a metallic component, a ceramic component, and at least one spring element arranged between the metallic component and the ceramic component. The metallic component has a first coefficient of thermal expansion, and the ceramic component has a second coefficient of thermal expansion. The at least one spring element is configured to mechanically couple the ceramic component to the metallic component.

High temperature compliant metallic elements for low contact stress ceramic support

An example method of mounting a first component to a second component includes receiving at least a fastening assembly within an aperture established in the first component, the fastening assembly coupled to the second component via a linking member, positioning a felt metal material between the fastening assembly and the first component, securing the fastening assembly, and compressing the felt metal material during the securing.

Method and apparatus for attaching components having dissimilar rates of thermal expansion

An exemplary method of adjustably mounting a first component to a second component includes, among other things, securing the first component to the second component with a linking member, and selectively adjusting the temperature of a variable portion of the linking member to change a size of the linking member.

Method and assembly for attaching components

An example mounting assembly includes a fastener receivable within an aperture of a component. A felt metal gasket separates the fastener from the component.

A multi-component fastener is provided having a body and a sleeve. The body has a shank that extends lengthwise between a head and a distal end. The shank includes a first outer surface. The body includes a first material. The sleeve has a wall defined by an outer surface and an inner surface. The inner surface defines an interior cavity. The wall extends lengthwise between a first end and a second end. At least a portion of the sleeve outer surface contiguous with the first end is threaded. The sleeve includes a second material that is dissimilar to the first material. A portion of the shank including the distal end is disposed within the interior cavity of the sleeve. The sleeve and the shank are fixed to one another.

Multi-component fastener and method of producing the same

An example adjustable linking member of a mounting assembly includes a first attachment portion and a second attachment portion. The first attachment portion connects a linking member to a first component. The second attachment portion connects the linking member to a second component. A variable portion of the adjustable linking member varies a distance between the first attachment portion and the second attachment portion in a first direction when heated. The variable portion varies the distance between the first attachment portion and the second attachment portion in a second direction when cooled. The first direction is opposite the second direction.

An article includes a ceramic matrix composite substrate with a heat-exposure surface and a monocoating disposed directly on the heat-exposure surface. The monocoating includes vitreous glass to seal the ceramic matrix composite from the surrounding environment.
