摘要
A composite has a) a PMC layer, and b) a tile layer comprising a plurality of Ox/Ox CMC tiles each has: i) a central portion, ii) an outer portion disposed surrounding the central portion, the bottom surface of the outer portion is disposed flush with the bottom surface of the central portion, the tile layer forms a smooth continuous top surface and a smooth continuous bottom surface, and the tiles are disposed with respect to one another such that each tile is inverted with respect to an adjoining tile, and iii) one or more overlap joints formed by the overlapping of the outer portions of adjoining tiles, so that hot gases entering the smooth top surface of the tile layer between abutting outer and central periphery segments must travel laterally between the overlapping outer portions of adjoining tiles to reach the top surface of the PMC layer.
