METHOD AND APPARATUS FOR MOLDABLE MATERIAL FOR TERRESTRIAL, MARINE, AERONAUTICAL AND SPACE APPLICATIONS WHICH INCLUDES AN ABILITY TO REFLECT RADIO FREQUENCY ENERGY AND WHICH MAY BE MOLDABLE INTO A PARABOLIC OR RADIO FREQUENCY REFLECTOR TO OBVIATE THE NEED FOR REFLECTOR CONSTRUCTION TECHNIQUES WHICH PRODUCE LAYERS SUSCEPTIBLE TO LAYER SEPARATION AND SUSCEPTIBLE TO FRACTURE UNDER EXTREME CIRCUMSTANCES

Abstract

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0037] In accordance with traditional methods for manufacturing parabolic reflectors, FIG. 1A depicts a parabolic assembly surface 102 made by quasi-parabolic reflector surfaces made of concentric strip rings in a multilayer substrate 104 (p represents the axes in the plane of the substrate which can be x or y 110) where T represents the total thickness of the substrate 106. FIG. 1A shows a three-dimensional view 100 of a parabolic reflector. FIG. 1B shows a lateral view 108 of the parabolic reflector in FIG. 1A.

[0038] In accordance with alternatives to the processes depicted in FIG. 1, other corresponding techniques have been used in the parabolic reflector manufacturing process, wherein various techniques have been used to achieve the integration of layered or sandwiched dissimilar materials, such as metallic inserts, adjacent various dielectric layers. In no case do prior art methods achieve the result of the present invention which enables the overall parabolic reflector to be formed from a single mixture of slurry, to form a homogeneous reflector, which possesses uniform levels of reflective throughout its cross-section and entire volume. Consequently, efficiency, signal to noise ratio and durability, strength and light weight design are all maximized in a streamlined simple manufacturing process.

[0039] FIGS. 2 A-B are renderings of carbon fiber materials used in connection with the present invention. In accordance with the preferred embodiment of the present invention, the epoxy matrix of the present invention requires materials such as conductive carbon black nanofibers and/or carbon nanotubes 200, as shown in the rendering of FIG. 2A, and graphite or graphene powder 202, as shown in the rendering of FIG. 2B. To clarify this process, in order to practice the present invention, a manufacturer would start with a parabolic shaped forming surface 300 as shown in FIG. 3. That shaping surface is simply the shape of the article you wish to create: a parabolic reflector or a parabolic reflector broken up into four petals or quadrants that may be bolted together, a maritime vessel, a spacecraft, an aviation asset, building supplies particularly which are earthquake resistant, and so forth. The parabolic forming surface 300 may be made of any material desired such as wood, plaster, stainless steel, aluminum, or any other material suitable for accepting a coating containing the desired elements. The forming surface 300 may be sprayed or otherwise coated prior to application of the reflective resin material (slurry) according to the present invention, again, much like a griddle may be coated prior to cooking a pancake. Such a coating acts as a release material so that the formed member or parabolic reflector portion or unit may easily be separated from the forming surface 300. Upon that forming surface is applied a low viscosity resin (or epoxy), carbon nanotubes and/or carbon nanofibers 200, graphite powder (or a graphene powder) 202, and then finally, while heated, a hardener is added to allow the hardening or curing process to lock into place the desired shape of the article desired to be manufactured. Alternatively, a heat box may be used to cure the slurry into the finished product. The hardener is selected to correspond with the resin chosen, such that the resin and hardener act in concert with the carbon nanotubes, carbon nanofibers, and graphite powder to form a homogeneous parabolic reflector unit or portion thereof.

[0040] FIG. 3 is an image of a shaping surface used in connection with shaping a parabolic reflector surface according to the present invention. In accordance with the preferred embodiment, the epoxy mixture or slurry is applied upon the shaping surface 300 so that upon hardening, a parabolic reflector may be formed of before unheard-of characteristics. The parabolic reflector slurry is applied to a mold or forming surface 300 as displayed in FIG. 3 and as it dries and cures, the hardener contained within it produces the desired result, much the way pancake batter is formed on a cooking skillet. The ingredients all disperse themselves throughout the finished article.

[0041] FIG. 4 is an image of a step according to the present invention. In accordance with the preferred embodiment of the present invention, the slurry possessing the required or desired reflective characteristics are applied to the forming surface. One important ingredient in the slurry is a epoxy resin, which mix with the carbon nanotubes, carbon nanofiber and graphite powders to create the finished parabolic reflector 400 as shown in the image of FIG. 4. Importantly, the carbon nanotubes align themselves naturally within the article being formed as they are polarized. The carbon nanofiber is similarly conductive, so it adheres to the carbon nanotubes and in turn, the graphite powder or graphene powder fills in the matrix so that the overall slurry has uniformly dispersed reflective properties distributed uniformly throughout the mixture of resin and hardener.

[0042] According to the present invention. In accordance with the preferred embodiment of the present invention, the epoxy matrix 500 of the parabolic reflector consists of a carbon fiber nanotube 502 and nanofiber structure and graphite powder 504, mixed together with resin and a hardener, as shown in the detailed image in FIG. 5.

[0043] FIGS. 6A & 6B show a parabolic reflector as being assembled, 6A with two quadrants connected together 600 and 6B at three of four quadrants joined together 602, perhaps with bolts to secure the petals to one another. Of course, the parabolic reflector may be formed in one piece or in several pieces for assembly upon usage requirement. In the present embodiment, the parabolic reflector is shown made up of quadrants, so that it may be stored and transported in a portable fashion, easily brought onto an airplane, for example.
