摘要：
Nozzles are presented, for application of a setting resin into cells of a honeycomb core to provide the panel with reinforced segments. The nozzle comprises a connector portion and an application head, where the connector portion is adapted to receive setting resin from a resin dispensing device and deliver the setting resin to the application head, and the application head comprises: an exit hole, and a flange surrounding the exit hole. The flange comprises a bottom surface which comprises a planar surface which planar surface has a minimum width around the exit hole. The bottom surface of flange curves upward at its outer perimeter. In some embodiments, the nozzle is optically translucent or transparent. In addition, methods of applying a setting resin into cells of a honeycomb core to form a honeycomb core reinforcement are presented. In some embodiments, the setting resin is a low density void filler.
