Title: System and method for thermally adaptive materials

Abstract

An adaptive sheet that includes a first layer defining a first length, the first layer configured to assume a base configuration in response to a first environmental condition and assume a lofted configuration in response to a second environmental condition with the first layer being curled along the first length compared the base configuration. The first fabric layer includes a first material defining a second length and having a first expansion coefficient, and wherein the first material is configured to increasingly change length along the second length in response to the second environmental condition, and a second material defining a third length and having a second expansion coefficient that is different than the first expansion coefficient.
