Study on Manufacturing Technology of Shaped Composite Antenna Reflector

The forming and processing methods of the antenna reflector with composite materials were analyzed from the aspects of material selection,mold design,process plan and process control.Carbon fiber single band was selected as the panel material of antenna reflector.The surface quality and machining precision of reflector can be improved effectively by using the more mature autoclave forming method for shaped antenna reflector.The combination curing method of dry skin and honeycomb core was selected as the forming method of reflector.Due to the large curvature change of reflector,the honeycomb core is prone to warping deformation and large residual stress when the honeycomb core is laid with the whole sheet.Therefore,it is necessary to preform the honeycomb core:the honeycomb core adopts the block splicing method.The result show that the shaped composite antenna reflector can achieve high precision machining when choosing the high-performance carbon fiber composite materials,using the autoclave moulding technology and carrying out the paving process control and aging treatment.
