摘　　要：以碳纤维复合材料天线反射面为研究对象,从栅格天线反射面的结构分析出发,研究热压罐中温固化成型树脂基碳纤维复合材料栅格天线反射面的制造工艺。通过设计栅格天线反射面成型模具结构,采用硅胶条粘接形成天线反射面的栅格结构,选择碳纤维预浸料单向带和碳纤维预浸布混合铺层,以中温固化的真空袋-热压罐成型工艺制造了栅格天线反射面,装配后反射面型面的精度符合要求。Based on the analysis of the structure of the grid antenna reflector,the manufacturing technology of the resin-based carbon fiber composite grid antenna reflector cured at medium temperature in autoclave was studied.By designing the mold structure of the grid antenna reflector,using the silicon glue stick to form the grid structure of the grid antenna reflector,selecting the carbon fiber prepreg unidirectional tape and the carbon fiber prepreg cloth mixed layer,the reflective surface of the grid antenna is fabricated by the vacuum bag-autoclave molding technology with medium temperature curing.The precision(RMS)of the surface is in accordance with the requirement.
