Abstract

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.

First claim

What is claimed is:

1. A fiber-reinforced aerogel composite, having:
a) a density between 0.01 g/cc and 0.30 g/cc;
b) a thermal conductivity at ambient temperature and ambient pressure of between 15 mW/m-K and 30 mW/m-K; and
c) a flexural strength between 105 psi and about 275 psi.

2. The aerogel composite of claim 1 , wherein the thermal conductivity of the aerogel composite at ambient temperature and ambient pressure is between 15 mW/m-K and 25 mW/m-K.

3. The aerogel composite of claim 1 , wherein the thermal conductivity of the aerogel composite at ambient temperature and ambient pressure is between 15 mW/m-K and 20 mW/m-K.

4. The aerogel composite of claim 1 , wherein the aerogel composite 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.

5. The aerogel composite of claim 1 , wherein the flexural strength of the aerogel composite is between about 150 psi and about 275 psi.

6. The aerogel composite of claim 1 , wherein the flexural strength of the aerogel composite is between about 200 psi and about 275 psi.

7. The aerogel composite of claim 1 , wherein the aerogel composite has a flexural modulus between about 5,000 psi and about 46,000 psi.

8. The aerogel composite of claim 7 , wherein the flexural modulus of the aerogel composite is between about 15,000 psi and about 46,000 psi.

9. The aerogel composite of claim 7 , wherein the flexural modulus of the aerogel composite is between about 25,000 psi and about 46,000 psi.

10. The aerogel composite of claim 1 , wherein aerogel composite comprises a polyimide aerogel or derivative thereof.
