Abstract
A gas turbine engine combustor liner with improved high temperature capability is achieved by embedding ceramic tiles into a fiber reinforced glass ceramic matrix composite substrate, so as to incorporate a space between the tiles and the substrate, the space serving to eliminate a direct heat conductive path between the tile and the substrate. The space is created by inserting a fugitive layer between the tiles and the substrate prior to compaction of the substrate, followed by removal of the fugitive layer. A fugitive material sprayed on the supportive region of the tiles prior to liner fabrication prevents the substrate material from bonding to the tiles, and prevents cracking of the tiles during temperature cycling.
