The Integration and Manufacturing Technologies on Large Double Curved Reflector CFRP Antenna

The large double curved reflector CFRP antenna is characterized by light weight, high strength and rigidity, high surface precision and so on. It is fit for applying to several types of radar system, such as airborne and aerostat-borne radars demanding relatively lighter weight. Combined with its features, the paper analyzes the main factors effect the surface precision of the reflector, such as stiffness and jointing, and introduces key manufacturing technologies, such as optimizing of technics flow, mould design, joint strengthen and precision examine. The technology has been successfully applied to the manufacturing of the antenna with a dimension of 8 m × 4.5 m, which met the design requirements on weight, surface precision and stiffness, and also the performance of electricity was measured excellent.
