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
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.
