The present invention introduces the use of a carbon nanotube-based material in the production of phased array patch antennas of various shapes and sizes including slot and spiral patch antennas. The use of this material provides the ability for the antennas to withstand high-intensity shock vibrations and other intense disturbances and continue emitting phased array signals. Furthermore, the use of this material for patch antennas allows for the alteration of the desired frequency and directional degree of interest by simply energizing various elements within the carbon nanotube-based material.

The present invention is directed to the production of shipping containers, computer server farm containers, and other forms of physical storage containers from a carbon nanotube-based fiber material with the potential application of other, non-carbon, nano-based materials containing various structures. Current materials used for shipping containers, computer server farm containers, and other forms of physical storage containers are heavier than the present invention and lack the ability to withstand high-intensity shock vibrations and other disturbances and are vulnerable to radiofrequency (“RF”) radiation. Instead of using metal, which is the currently preferred material used in the development of shipping containers, computer server farm containers, and other forms of physical storage containers, the present invention provides the use of a carbon nanotube-based material.

A method is provided to fasten a pin in a target position extending at least partially into a cavity with a distance (D) between a bottom surface of the cavity and a facing end of the pin. The pin is positioned at the target position, and the distance (D) is determined between the bottom surface of the cavity and the facing end of the pin in the target position. The pin is removed from the cavity, and a rigid spacer is applied on the bottom surface. A thickness of the rigid spacer equals the distance (D) between the bottom surface and the facing end of the pin in the target position. The adhesive is filled into the cavity onto the rigid spacer, and the pin is repositioned at the target position. The adhesive is then cured to obtain a joint between the pin and the second component.

A method is provided for joining a pin member of a first component to a second component with a cavity, using an adhesive, to fasten the pin in a target position extending at least partially into the cavity. A distance (D) is provided between the bottom surface of the cavity and the facing end of the pin. A flexible spacer is positioned on the bottom surface of the cavity. The thickness of the spacer equals or exceeds the distance (D) between the bottom surface of the cavity and the facing end of the pin in the target position. The adhesive is filled into the cavity onto the flexible spacer, and the pin is positioned in the target position. The adhesive is cured to obtain a joint between the pin and the second component.

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.
