Aerogel insulation panels and manufacturing thereof
View Patent ↗The present invention provides articles and methods related to insulation panels made from aerogels, and specifically polyimide based aerogels. Such insulation panels have a wide variety of applications, including specifically in aerospace applications.
1. A laminate panel, comprising:
a first layer including a fiber-reinforced aerogel composite, wherein the fiber-reinforced aerogel composite has
a density between 0.01 g/cc and 0.30 g/cc;
a thermal conductivity at ambient temperature and ambient pressure of between 15 mW/m-K and 30 mW/m-K, and
a flexural strength between 105 psi and about 275 psi; and
a second layer including a facesheet disposed on a major face of the first layer.
2. The panel of claim 1 , wherein the panel comprises at least one vent and at least one vent filter.
3. The panel of claim 1 , wherein the thermal conductivity of the first layer at ambient temperature and ambient pressure is between 15 mW/m-K and 25 mW/m-K.
4. The panel of claim 1 , wherein the thermal conductivity of the first layer at ambient temperature and ambient pressure is between 15 mW/m-K and 20 mW/m-K.
5. The panel of claim 1 , wherein the first layer has a thermal conductivity at ambient temperature and vacuum pressure at 10-5 Torr of between 1 mW/m-K and 5 mW/m-K.
6. The panel of claim 1 , wherein the flexural strength of the first layer is between about 150 psi and about 275 psi.
7. The panel of claim 1 , wherein the flexural strength of the first layer is between about 200 psi and about 275 psi.
8. The panel of claim 1 , wherein the first layer has a flexural modulus of between about 5,000 psi and about 46,000 psi.
9. The panel of claim 8 , wherein the flexural modulus of the first layer is between about 15,000 psi and about 46,000 psi.
10. The panel of claim 8 , wherein the flexural modulus of the first layer is between about 25,000 psi and about 46,000 psi.
11. The panel of claim 1 , wherein the aerogel composite comprises a polyimide aerogel or derivative thereof.
12. The panel of claim 1 , further comprising a third layer including a second facesheet disposed on an opposite major face of the first layer.
13. The panel of claim 1 , wherein the panel has at least one edge sealed by at least one edge seal.
14. The panel of claim 13 , wherein the at least one edge seal comprises at least one vent and at least one vent filter.
15. The panel of claim 13 , wherein the first facesheet, the second facesheet, and the at least one edge seal encloses an interior panel space and exclude an exterior space.
16. The panel of claim 15 , wherein the at least one edge seal comprises at least one vent; and wherein the vent allows air to flow between the interior panel space and the exterior space.
17. The panel of claim 16 , wherein the at least one edge seal further comprises at least one vent filter; wherein the interior panel space comprises aerogel particles; and wherein the at least one vent filter prevents the aerogel particles from passing from the interior panel space to the exterior space.
18. The panel of claim 17 , wherein the aerogel composite comprises a polyimide aerogel or derivative thereof.
