Carbon fiber copper-clad composite material and application thereof as antenna radiator

Abstract

The invention discloses a carbon fiber copper-clad composite material, which comprises two or more sections of carbon fiber circular tubes, wherein a copper mesh is embedded in the surface of each carbon fiber circular tube, the carbon fiber circular tubes are connected by means of metal joints, the metal joints and the carbon fiber circular tubes are assembled by riveting or screwing, the metal joints and the copper meshes are welded together by silver welding, an epoxy laminated glass fiber cloth wraps the copper meshes and the metal joints, and finally the surface of the epoxy laminated glass fiber cloth is coated with a paint. According to the carbon fiber copper-clad composite material disclosed by the invention, a main force loading layer is a carbon fiber material of the inner layer, and the copper meshes of the intermediate layer achieve a conductive function, thus the material properties of low density and high strength of the carbon fibers are reserved, and the conductivity of the carbon fibers is improved. The epoxy laminated glass fiber cloth of the outermost layer and the paint on the surface thereof are non-metallic materials, can protect the copper meshes from oxidation and corrosion while ensuring that the copper meshes can radiate electromagnetic signals.
