Abstract: A damage tolerant component (90) for use in a high temperature combustion gas environment. The component includes a plurality of ceramic tiles (94) bonded to a substrate (92) for isolating any impact damage to the damaged tile(s). A grout (98) may fill gaps between adjacent tiles to blunt any crack tip extending from a damaged tile. Ceramic tile insulation may be applied in two layers (56, 58) with the material properties of the two layers being different, such as with a bottom layer selected for its thermal insulating properties and a top layer selected for its impact resistance properties. A layer of sealing material (100) may be applied over at least a portion of the ceramic tiles.

Abstract: The interlocking of two or more sections via the insertion of one or more out-of-plane features in one section or combination of sections through a void in one or more a complementary sections can result in a reinforced ceramic matrix composite article upon securing of the sections. The sections can be secured by friction between two tightly matched sections or by the use of a pin, hook, or clamp. The sections can be constructed from one or more CMC laminate sheets. The out-of-plane feature can be a loop or a flange and the void can be an orifice or a matched loop in the complementary sheet. The securing of the sections can result in a CMC article where the delamination between sheets is inhibited.
