Fiber-Plastic Composite Parts to Replace the Heavier Aluminum Variant in Airbus
Series Production of CFRP Window Frames
Mold, machine and plant maker BBG GmbH & Co. KG, Mindelheim, Germany, together with its customer, has developed, built and shipped an end-to-end production line for the series production of CFRP window frames for the Airbus A350. The recipient is ACE Advanced Composite Engineering GmbH, Immenstaad am Bodensee, Germany, which produces components made of carbon-fiber-reinforced plastic for Airbus at its manufacturing site in Hagnau, Germany.
The production line includes two BFT-C mold carrier systems that feature mounting dimensions of 1,000 mm x 1,000 mm and which are designed as a press with a clamping force of 1,000 kN, an in-mold turning unit and a demolding unit. An automatic mounting system, with a maximum clamping force of 20 kN, first secures the mold in the in-mold turning unit. Thereafter, the two parts of the mold are separated by being lifted in a short parallel movement and swung open 180 degrees. The ergonomic design allows the operator to easily insert the prepared carbon fiber preforms into the mold.
The in-mold turning unit has a fully insulated heat chamber with integrated heating plates for energy-efficient mold heating. The mold containing the preforms is then loaded by a special trolley into the BFT-C mold carrier, the resin is then injected and the component is baked. Finally, the mold is opened in the mold carrier and the component goes to the demolding unit. This can be swung open 180 degrees so that the window frame is easy to remove.
