Abstract
The present invention is generally directed to tapes designed for use in conjunction with lighter-than-air vehicles, platforms or other inflated structures. In one embodiment, the present invention is directed to conductive seam cover tape that can be, for example, used to protect and/or cover one or more seams in a lighter-than-air vehicle, platform or other inflated structure. In another embodiment, the present invention is directed to a conductive seam cover tape that can be, for example, used to protect and/or cover fabric panels or sections that are used to form lighter-than-air vehicles, platforms or other inflated structures that are in, one instance, designed for deployment at high altitudes.
Claims19
A seaming tape comprising:
- a tape having three layers;
- a first layer, the first layer being formed from at least one adhesive composition and where the first layer has an upper surface and a lower surface;
- a second layer, the second layer being formed from at least one polymer composition that possesses gas barrier properties, where the second layer has an upper surface and a lower surface and the lower surface of the second layer is oriented toward and in contact with the upper surface of the first layer;
- and
- a third layer, the third layer being formed from one or more UV-resistant polymer compositions, where the third layer has an upper surface and a lower surface and the lower surface of the third layer is oriented toward and in contact with the upper surface of the second layer,
- where at least one of the first, second and third layers is electrically conductive, and at least one of the first, second and third layers is electrically non-conductive.
A seaming tape for sealing and/or reinforcing the seams in a hull of a lighter-than-air vehicle where the tape comprises:
- a tape having four layers;
- a first layer, the first layer being formed from at least one adhesive composition and where the first layer has an upper surface and a lower surface;
- a second layer, the second layer being formed from at least one polymer composition that possesses gas barrier properties, where the second layer has an upper surface and a lower surface and the lower surface of the second layer is oriented toward and in contact with the upper surface of the first layer;
- and
- a third layer, the third layer being formed from one or more UV-resistant polymer compositions, where the third layer has an upper surface and a lower surface and the lower surface of the third layer is oriented toward and in contact with the upper surface of the second layer;
- and
- a fourth layer, the fourth layer being formed from one or more clear UV-resistant polymer compositions, where the fourth layer has an upper surface and a lower surface and the lower surface of the fourth layer is oriented toward and in contact with the upper surface of the third layer,
- where at least one of the first, second and third layers is electrically conductive, and at least one of the first, second and third layers is electrically non-conductive.
