摘要：
An apparatus includes a metal shell (200, 300) surrounding a body (230, 330) that is made of a ceramic matrix composite (CMC) material (231) The metal shell defines a space (250) adapted to contain the body and includes at least one protrusion (220) adapted to contact the body. A compliant porous element (240) is adapted to fit in the space between the metal shell and the body. A preload spring (260, 360) is provided in an urging orientation with the body wherein the preload spring is positioned against a first region (333) of the body and is adapted to urge the body toward one of the protrusions positioned against a second region (335) generally opposite the first region, and also to preload the compliant porous element. One of the protrusions may be a hard stop, and in the preload, one of the protrusions may be loaded.
