Use of a structure as a heat collector and a heat insulator

摘要

A honeycomb core 2 is bonded to a planar outer skin 10 by forming a pool of adhesive 24 on a surface of the outer skin and placing the honeycomb core 2 within the adhesive pool 24. In the resulting structure, a continuous layer of adhesive of substantially uniform depth is formed within the cells 8 of the honeycomb core 2. The depth of the adhesive and the size of the cells may be chosen so that the adhesive provides a lens effect on light passing through. The structures may be used for light, heat or sound transmission/retardation.
