Abstract:
1. A thermally stable structure comprising: a contiguous structure including a plurality of cell sides intersecting at a plurality of corners forming a plurality of cells, the contiguous structure consisting of a first material having a coefficient of thermal expansion greater than zero; and at least one insert located in a cell of the plurality of cells, the insert consisting of a second material having a second coefficient of thermal expansion greater than zero and different than the coefficient of thermal expansion of the first material, the insert oriented to connect to the cell sides of the plurality of cell sides forming the cell of the plurality of cells between corners of the plurality of corners corresponding to segments; wherein the plurality of cell sides bend as the first and second materials expand, wherein the at least one insert is in compression as the first and second materials expand, wherein the plurality of corners rotate as the first and second materials expand, and wherein the two materials structurally combined result in a coefficient of thermal expansion of the thermally stable structure less than the first material coefficient of thermal expansion and less than the second material coefficient of thermal expansion.
