SYSTEM AND METHOD FOR THERMALLY ADAPTIVE MATERIALS

摘要

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.

1. A thermally adaptive garment configured to be worn on and surround the body of a user, the thermally adaptive garment comprising:
a garment body defined by a thermally adaptive fabric that includes:
an internal face configured to face the body of a wearing user;an external face configured to face an environment external to the wearing user;a first fabric layer defining at least a portion of the external face;a second fabric layer defining at least a portion of the internal face and coupled to the first fabric layer at one or more coupling seams; anda plurality of cavities defined by and disposed within the first and second fabric layer and the one or more coupling seams; wherein the first fabric layer is configured to assume a base configuration in response to a first environmental temperature range with the first fabric layer being separated from the second fabric layer by a first average distance; and wherein the first fabric layer is configured to assume a lofted configuration in response to a second environmental temperature range separate from the first environmental temperature range with the first fabric layer being separated from the second fabric layer by a second average distance that is greater than the first average distance.
