Lightweight honeycomb thermal insulation structure
A honeycomb thermal insulation structure may comprise a first facesheet, a second facesheet, and a honeycomb core between the first facesheet and the second facesheet. The honeycomb core may include a plurality of honeycomb unit cells each composed of walls having a height and spaced by a distance. The walls of the honeycomb cells may have perforations. The honeycomb thermal insulation structure may further comprise a non-convective gas loaded in the honeycomb unit cells between the walls. A flow of the gas through the perforations may be substantially absent.
