A method for making a thermal insulating structure for providing thermal insulation, structural load accommodation, and noise attenuation for surfaces in aerospace systems that are exposed to high temperatures is disclosed. Structure to be protected is a high-temperature solid back sheet to which is a honeycomb core having a perforated buried septum is bonded to a substrate. A layer of cast fiber-ceramic insulation is secured to the honeycomb core, filling portions of the core outward from the septum and extending beyond the outer face of the core. To absorb structural loads, a densified top coat overlies the insulating layer. To minimize the transmission of shear-inducing loads into the insulating layer, the outer face of the honeycomb core has an irregular surface. Core cell vents extending through the walls of adjacent cells provide a controlled airspace between the back sheet and the buried septum through which a fluid coolant may be circulated.

A method for making a ceramic insulation, comprising the steps of: (a) forming a honeycomb core with a textured surface on at least one face, wherein the textured surface is formed by fraying the face of the core; (b) forming a ceramic insulation layer in an upper portion of each cell of the honeycomb core by vacuum casting a slurry of ceramic fibers into the core; (c) forming a transition zone in the insulation by continuing to case the slurry over the textured surface; (d) continuing to cast an integral layer of ceramic fiber insulation to extend in a sheet over the transition zone; and (e) adhering a reinforced glass layer to the sheet.
