Abstract
Thermal insulation assemblies and methods for fabricating thermal insulation assemblies are provided. In an exemplary embodiment, a thermal insulation assembly comprises a ceramic tile having a surface coated with an alumina-mullite slurry. A ceramic matrix composite is disposed on the coated surface. The ceramic matrix composite comprises a first ply of a ceramic fiber impregnated with a ceramic matrix.
Claims19
A thermal insulation assembly, comprising:
- a ceramic tile having a surface coated with a slurry consisting essentially of alumina powder, mullite powder, and an alumina precursor solution;
- and
- a ceramic matrix composite facesheet disposed on the coated surface of the ceramic tile, the ceramic matrix composite facesheet comprising a first ply of a ceramic fiber impregnated with a ceramic matrix.
A method for fabricating a thermal insulation assembly, the method comprising the steps of:
- providing a machined ceramic tile having a surface;
- coating the surface of the ceramic tile with a slurry consisting essentially of alumina powder, mullite powder, and an alumina precursor solution;
- preparing a first ceramic matrix composite ply;
- applying the first ceramic matrix composite ply overlying the coated surface of the ceramic tile;
- and
- curing the first ceramic matrix composite ply.
