The large dimension super light-weight rigid carbon fiber composite antenna fabrication technique with rubber bar mandrel
For fabrication large dimension scale super light-weight and rigid carbon fiber composite antenna, a new fabrication technique with flexible Rubber Bar Mandrel(RBM) combine autoclave process was developed through process tests. The rigid antenna structure was designed according with the RBM technique process, and the antenna which has 8000. 5000 mm2 aperture, surface accuracy (RMS) is 0.95mm, weight 126kg including reflector, support frame, feed horns and radius rods.
