Abstract
A back rib fused carbon-fiber composite material satellite antenna reflector disclosed by the present invention comprises a reflector body and back ribs, the reflector body adopts a composite material core sandwich structure and comprises a reflector outer skin and a reflector inner skin, and the back ribs comprise a right back rib and a left back rib. The right and left back ribs are arranged on the reflector outer skin integrally and are equipped with the back rib external interfaces, and the reflector body and the back ribs are both made of the carbon-fiber composite materials. The right and left back ribs are mirror image members with each other about the middle surface of the reflector outer skin, and are hollow thin-wall structures. The back rib fused carbon-fiber composite material satellite antenna reflector of the present invention is simple in structure, enables the back rib assembly workload to be reduced greatly, overcomes the insufficiency of the conventional carbon fiber reflector and an aluminum alloy back frame, and is light in reflector weight, high in positioning precision and good in size stability and environment adaptability by fusing the back ribs and the reflector body.
