Abstract

See full text

A method for reworking a ceramic structure. A portion of a first facesheet is removed from the ceramic structure to form a first aperture. The first facesheet comprises a number of layers of a first ceramic material. A portion of an inner section of the ceramic structure is removed to form a second aperture. The second aperture extends from the first aperture into the inner section. The inner section comprises a second ceramic material bonded to the first facesheet and has a lower density than the first facesheet. A ceramic replacement material is placed in the second aperture. A number of replacement ceramic layers are placed in the first aperture. Ceramic particles are placed between the first facesheet and the number of replacement ceramic layers. The ceramic particles are sintered to bond the number of replacement ceramic layers to the first facesheet.
