Abstract

A thermal management system utilizing a composite thermal radiation barrier comprising alternating layers of a carbon cloth insulating layer and a silica-based organic cloth to reduce the temperatures experienced by the insulating layer.

Claims

1. A method for increasing the thermal conductivity of a thermal blanket by the addition of organic materials to an insulating layer in order to increase the thermal conductivity of the occluded gases.

2. The method of claim 1 wherein said insulating layer is formed of silica fiber and said organic materials comprise silicone.

3. The method of claim 2 wherein the silicone coating is about 2 mils in thickness and has a weight of between 2 and 3 ounces per square yard of material.

9. The thermal radiation barrier of claim 3 wherein the carbon cloth layer is a woven or non-woven fabric.

4. A composite thermal radiation barrier comprising a silica fiber layer having a polymeric organic coating and disposed next adjacent to a carbon cloth layer.

5. The composite thermal radiation barrier of claim 4 further comprising a silica fiber ayer next adjacent to the carbon cloth layer.

6. The composite thermal radiation barrier of claim 4 further comprising a metallic layer.

7. The thermal radiation barrier of claim 4 wherein the polymeric organic compound is silicone applied in an amount sufficient to effectively enhance the thermal conductivity of the occluded gases and allow the carbon cloth layer to serve as improved insulating layer.

8. The thermal radiation barrier of claim 7 wherein the polymeric organic compound is applied by laminating, coating, brushing or spraying at a thickness of about 2 mils and a weight of between 2 and 3 ounces per square yard of said carbon cloth layer.

10. A thermal insulation blanket comprising at least two alternating layers of a silica fiber layer containing a polymeric organic compound and a carbon cloth layer.

11. The thermal insulation blanket of claim 10 wherein said eric organic compound is silicone applied by laminating, coating, brushing or spraying at a thickness of about 2 mils and a weight of between 2 and 3 ounces per square yard of said carbon cloth layer.

12. The thermal insulation blanket of claim 10 further comprising a primary insulation layer of silica.

13. The thermal insulation blanket of claim 12 further comprising a heat-resistant, flexible metallic woven or knit mesh layer as a reflective radiation barrier against radiant heat.

14. The thermal insulation blanket of claim 10 wherein the blanket is constructed without including fiberglass or ceramic materials.

15. The thermal insulation blanket of claim 10 wherein an encapsulation layer is draped around the primary insulation layer and radiation barrier layer so as to hold the primary insulation layer and radiation barrier layer secure.
