JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Award-winning innovation from Germany's traditional chemical producing region Saxony-Anhalt that saves costs and increases safety
The JEC Europe 2015 will take place in Paris from 10th to 12th Marc and is the world's leading exhibition on composites. Here, the German federal state of Saxony-Anhalt will present itself as a highly specialised centre of competence for composites and lightweight construction. In hall 7.3, booth L71, the state's Investment and Marketing Cooperation (IMG) will give an insight into versatile innovations and pioneering material solutions from Saxony-Anhalt. Also present: P-D Aircraft Interior, developers of a production process for pre-pegs that saves up to 35 percent of energy.Floor plates for aeroplanes, ultra-light and super strong. Bumper bars for Leipzig's trams, soft and yielding for improved personal protection. Two million flexible laminates as couplings for Shanghai's subway. Or elegantly glossy luggage compartment doors for a Lamborghini. P-D Aircraft Interior from the city of Bitterfeld-Wolfen produces pre-pegs, sandwiches and components from high-tech glass and carbon fibres with numerous application possibilities. Thanks to the innovation that the company has developed together with the Fraunhofer Institute for Mechanics of Materials IWM in the city of Halle, not only has energy been spared and costs reduced in the production of fibre reinforced plastic, but also the safety of components has been increased. The invention was awarded the Hugo-Junkers-Prize for research and innovation of the federal state of Saxony-Anhalt in 2014 for its resource efficiency.The business manager of P-D Aircraft Interior, a Preiss-Daimler group company, Gerhard Müller knows that "safety is the key argument in aviation". At the chemistry park in the city of Bitterfeld-Wolfen, the company developed ceiling panels, super-light and strong interior side walls, so-called side-wall panels, noise-reducing ventilation ducts as well as mirror panels all for aviation. The graduated process engineers stand a good chance of landing the manufacture of floors for Boeing or Airbus with the new process. But Gerhard Müller also finds the producers of smaller passenger or light aircraft interesting.Thanks to a new recipe, the epoxy resin soaked fibreglass fabric no longer has to be stored or transported at minus 30 degrees Celsius until further processing. They can now be stored at a maximum of 35 degrees Celsius for three months. When heating, the resin still develops the desired flow behaviour in order to connect it with the phenolic resin-impregnated aramide paper in a sandwich. 35 percent more energy can be saved thanks to this chemical change to the resin. And what is even more important to aviation: "The thawing process is dropped and with it the risk of the air humidity that can damage the pre-pegs," explains Müller. "This increases the product safety and quality reliability." Several of the company's components from Saxony-Anhalt are being tested by Airbus. They will be simulated for around two years to make sure that the products can withstand heavy-duty use without changing their properties.Manufacturers of residential house doors are not as concerned about safety, this mass market is dominated by price pressure. Energy saving in manufacture as well as the advantages of having a value-added chain within the Jürgen Preiss-Daimler group of companies also have an effect. The Preiss-Daimler group of companies are cultivating a strategic partnership in China where the glass fibres are produced. The sister factory in Oschatz which finely weaves the fibres belongs to the P-D fibreglass group. At P-D Aircraft Interior's industrial warehouse in Saxony-Anhalt, these fabrics then pass through into the impregnation machine, the so-called treater. They are impregnated with resin and guided over a roller system so that the resin is optimally distributed in and on the fabric. The manufactured laminate can then be wound dry onto rolls, stored or further processed. The sheets are then cut, pressed into each other and connected with a flexible or strong honeycomb into a sandwich."We subsequently design the components according to the properties that are required", explains Müller. Sometimes, the focus is on fire protection, or on flexibility or flexural strength, on weight, scratch resistance, water or oil resistance, ageing behaviour or resistance to impact. In this way, the range stretches from rigid flooring to extremely flexible couplings for subway carriages.More information:www.invest-in-saxony-anhalt.comBooth: L71
