Abstract

A radiant heat barrier insulation system includes a first substrate with a first layer of aluminum thereon. The system also includes a second substrate with a second layer of aluminum thereon. The first substrate is positioned to oppose the second substrate such that a gap is defined between the first substrate and the second substrate. The gap is filled with a randomly-oriented nest of carbon nanotube fibers.

First claim

What is claimed as new and desired to be secured by Letters Patent of the United States is:

1. A radiant heat barrier insulation system, comprising:
a first substrate having an inner and outer side;
a first layer of aluminum on said outer side of said first substrate;
a second substrate having an inner and outer side, said second substrate positioned so that said inner side of said second substrate opposes said inner side of said first substrate, forming a gap therebetween;
a second layer of aluminum on said outer side of said second substrate; and
a randomly-oriented nest of carbon nanotube fibers disposed within said gap.

2. A radiant heat barrier insulation system as in claim 1 , wherein at least one of said first substrate and said second substrate comprises a hydrophobic fabric.

3. A radiant heat barrier insulation system as in claim 1 , wherein at least one of said first substrate and said second substrate comprises a carbon nanotube fabric sheet.

4. A radiant heat barrier insulation system as in claim 1 , wherein said first substrate comprises a carbon nanotube fabric sheet and said second substrate comprises a hydrophobic fabric.

5. A radiant heat barrier insulation system as in claim 1 , further comprising:
at least one carbon nanotube fiber coupled to one of said first substrate and said second substrate adjacent to said gap; and
a DC current source coupled to said at least one carbon nanotube fiber.

6. A radiant heat barrier insulation system as in claim 1 , further comprising:
at least one carbon nanotube fiber coupled to one of said first layer of aluminum and said second layer of aluminum; and
a DC current source coupled to said at least one carbon nanotube fiber.

7. A radiant heat barrier insulation system as in claim 4 , further comprising:
at least one carbon nanotube fiber coupled to said first layer of aluminum; and
a DC current source coupled to said at least one carbon nanotube fiber.

8. A radiant heat barrier insulation system for an underwater diver, comprising:
a first flexible substrate comprised of a carbon nanotube fiber sheet and having an inner and outer side;
a first layer of aluminum on said outer side of said first substrate;
a second flexible substrate comprised of a hydrophobic fabric and having an inner and outer side, said second substrate positioned so that said inner side of said second substrate opposes said inner side of said first substrate, forming a gap therebetween;
a second layer of aluminum on said outer side of said second substrate; and
a randomly-oriented nest of carbon nanotube fibers disposed within said gap.

9. A radiant heat barrier insulation system as in claim 8 , further comprising:
a plurality of carbon nanotube fibers coupled to one of said first substrate and said second substrate adjacent to said gap; and
a DC current source coupled to said plurality of carbon nanotube fibers.

10. A radiant heat barrier insulation system as in claim 8 , further comprising:
a plurality of carbon nanotube fibers coupled to said first layer of aluminum; and
a DC current source coupled to said plurality of carbon nanotube fibers.
