Electromagnetic wave shielding carbon fiber honeycomb composite board square cabin

The invention relates to the technical field of square cabins, in particular to an electromagnetic wave shielding carbon fiber honeycomb composite board square cabin which comprises a metal plate and a metal frame, the metal plate is connected with a heat insulation foam board, a sound insulation layer is connected with a fiber layer, a honeycomb board is connected with a fixing plate, and an electromagnetic wave shielding layer is connected with a wave absorbing layer. The movable plate is connected with a spring, a honeycomb rod and a wave-absorbing rod, and the rubber pad is connected with a guide groove; during installation, the guide groove is aligned with the rubber pad and connected with the rubber pad, the spring is extruded by pressure, and then the square cabin plate and the metal frame are fixed through the fastening structure and are sequentially installed. Radar detection waves or electromagnetic waves sequentially pass through the reflecting layer, the metal plate, the heat insulation foam plate
