Airbus airplane door frame goes composite route

Wickert Maschinenbau GmbH (Landau, Germany) will be presenting a complete inner core door frame molded using the resin transfer molding (RTM) for the Airbus A 350 at this year's Composites Europe 2013 to be held 17-18 September at Messe Stuttgart in Germany. The highly stressable carbon fiber composite component is manufactured at Eurocopter in Donauwörth, Germany. This procedure makes it possible to produce structural components with comparatively high fiber volume content and good impact properties, while slimming down on weight at the same time.

Manufacturing is via an injection process that uses the Wickert WKP 2500 S Composite Press based on the proven modular system found in Wickert downstroke presses. Because the carbon parts cannot be exposed to even a hint of oil mist, the hydraulic press system was required to be absolutely oil-tight. This was achieved by completely enclosing the press area and the entire press technology peripheral system, including the hydraulic and electric systems....
