Abstract
The application discloses an antenna reflector based on high-conductivity pitch-based carbon fiber prepreg, which comprises, from outside to inside, a protective layer, an electromagnetic reflection functional layer and a structural support layer, and the electromagnetic reflection functional layer is obtained by curing high-conductivity pitch-based carbon fiber prepreg. The antenna reflector based on high-conductivity pitch-based carbon fiber prepreg provided by the application uses high-conductivity pitch-based carbon fiber prepreg obtained by providing anchor points through plasma treatment cabin activation and bridging of ultrasonic wave driven nano fillers, so that ultrahigh volume conductivity, excellent electromagnetic shielding efficiency and excellent space thermal cycle stability comparable to metal can be achieved without relying on secondary metallization. The electromagnetic wave reflectivity of the obtained antenna reflector at 10 GHz is not less than 95%, and the surface density is not higher than 1.6 kg / m2, which can meet the integrated requirements of light weight, high conductivity and high shielding performance.
