Dynamic materials integrated into articles for adjustable physical dimensional characteristics
Systems and methods of integrating dynamic materials into articles for adjustable physical characteristics, e.g., aesthetic, functional. For example, in response to a human's body heat, a dynamic material may change shape to allow additional permeability in an article of clothing. Similarly, in response to the presence of moisture, an article of clothing may close a vent to prevent the introduction of rain into an internal portion of the article. The shape changing material may change shape that merely affects a feature formed by the shape changing material. Additionally, it is contemplated that the shape changing material may change shape that affects a geometric structure of the article as a whole, e.g., protrusions, dimples, vents, etc.
1. A woven material, comprising:
a plurality of warp yarns comprising a shape memory polymer material; and
a plurality of weft yarns comprising a material different than the shape memory polymer material,
wherein the shape memory polymer material has a programmed shape associated with a stimulus, and
wherein, when the shape memory polymer material is exposed to the stimulus, it reverts to the programmed shape, thereby creating a deformation in the woven material.
2. The woven material of claim 1 , wherein the deformation forms a separation in the plurality of warp yarns that creates an opening.
3. The woven material of claim 1 , wherein the programmed shape is a non-linear configuration of the plurality of warp yarns.
4. The woven material of claim 1 , wherein the deformation of the woven material creates a void in the woven material.
5. The woven material of claim 1 , wherein the programmed shape results in at least some of the plurality of warp yarns separating from each other.
6. The woven material of claim 1 , wherein the deformation of the woven material occurs in response to receiving a predetermined level of intensity of the stimulus, wherein the stimulus is moisture or the stimulus is heat.
7. A woven material, comprising:
a plurality of warp yarns and a plurality of weft yarns,
wherein one or more of the plurality of warp yarns and/or one or more of the plurality of weft yarns comprise a shape memory polymer material,
wherein the shape memory polymer material has a programmed shape associated with a stimulus, and
wherein, when the shape memory polymer material is exposed to the stimulus, it reverts to the programmed shape, thereby creating a deformation in the woven material.
8. The woven material of claim 7 , wherein the deformation forms a separation in the plurality of warp yarns and/or the plurality of weft yarns that creates an opening.
9. The woven material of claim 7 , wherein the deformation generates a void in the woven material.
10. The woven material of claim 7 , wherein removal of the stimulus causes the woven material to transition to a state without the deformation.
11. The woven material of claim 7 , wherein the deformation of the woven material occurs in response to receiving a predetermined level of intensity of the stimulus, wherein the stimulus is moisture or the stimulus is heat.
12. A method of manufacturing a woven material, the method comprising:
weaving a plurality of warp yarns comprising a shape memory polymer material with a plurality of weft yarns, thereby forming the woven material, wherein the shape memory polymer material has a programmed shape associated with a stimulus; and
exposing the shape memory polymer material to the stimulus so that it reverts to the programmed shape, thereby creating a deformation in the woven material.
13. The method of manufacturing the woven material of claim 12 , wherein the plurality of weft yarns comprise a material different than the shape memory polymer material.
14. The method of manufacturing the woven material of claim 12 , wherein the plurality of weft yarns comprise the shape memory polymer material.
15. The method of manufacturing the woven material of claim 12 , wherein in response to the stimulus, adjacent warp yarns of the plurality of warp yarns move in opposing directions to create a void in the woven material.
16. The method of manufacturing the woven material of claim 12 , wherein in response to the stimulus, the plurality of warp yarns transition from a linear shape to a non-linear shape to create the deformation in the woven material.
17. The method of manufacturing the woven material of claim 16 , wherein the deformation of the woven material is removed in response to removal of the stimulus.
18. The woven material of claim 1 , wherein the material different than the shape memory polymer material is a non-shape memory polymer material.
19. The woven material of claim 7 , wherein the shape memory polymer material comprises a composite of two or more shape memory polymers.
20. The method of manufacturing the woven material of claim 13 , wherein the material different than the shape memory polymer material is a non-shape memory polymer material.
