Abstract

The invention discloses a method for manufacturing a large-caliber high-precision composite material antenna surface, which relates to an antenna reflection surface manufacturing technology in the fields of satellite communication, radio measurement and control, deep space detection, and large radio telescopes. The main reflector is a large-diameter parabolic structure, which is integrally formed on the mold by composite material vacuum infusion technology. The back frame is a composite foam sandwich structure, which is composed of transverse ribs and longitudinal ribs in a vertical and horizontal orthogonal manner with a spatial grid structure. support body. This method can successfully prepare large-caliber (Φ>10m), high-precision (δ<0.3mmRMS) antenna reflective surface, and make it have the advantages of light structure, high rigidity, good shock resistance and high production efficiency.

Description

technical field [0001] The invention relates to the field of antenna reflective surface manufacturing engineering, in particular to an integral molding manufacturing technology of a large-diameter high-precision composite material antenna surface. Background technique [0002] The development of communication technology and the urgent need for deep space exploration require that the radar antenna reflector has the characteristics of high precision and large aperture. In the field of radar antenna manufacturing engineering, the fiber reinforced composite reflector is characterized by its light weight, high specific The advantages of large size, high precision and good designability more replace the traditional metal reflective surface. Most of the existing high-precision composite antenna reflectors are small-diameter reflectors prepared by the autoclave molding process. How to use the advantages of composite materials to design and manufacture large-diameter (Φ>10m) and h...
