    At the JEC 2018 fair in Paris (6-8 March) the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM will present for the first time the use of flexible FlexPLAS® release film in complex hot press molds. You are invited to visit us on the communal stand of CFK Valley in Hall 5 A, Stand E 58. The plasma-coated FlexPLAS® release film developed by Fraunhofer IFAM (Bremen and Stade) has already been successfully used for a number of years for the manufacture of contaminant-free fiber reinforced plastic (FRP) components.

  • How to Program Materials

    Ali Gooneie looks at a sample from his most recent research project: electrically conductive polymers. The first calculations for his next project are sketched out on the blackboard. Empa

    Can the properties of composite materials be predicted? Empa scientists have mastered this feat and thus can help achieve research objectives faster. This leads, for instance, to better recycling techniques and electrically conductive synthetic materials for the solar industry. Ali Gooneie simulates on his computer what holds the world together right at its very core: atoms, molecules, molecular chains and bundles – then lumps and fibers, which emerge thereof. With his calculations, the Empa researcher can also explain properties we can feel with our fingertips: smooth and rough surfaces, flexible and rigid materials, heat-conductive substances and insulators.

  • LZH optimizes laser-based CFRP reworking for the aircraft industry

    To be able to rework aircraft components made of carbon-fiber reinforced plastics (CFRP) more efficiently in the future, the Laser Zentrum Hannover e.V. (LZH) has started the joint research project ReWork together with the INVENT GmbH, OWITA GmbH und Precitec Optronik GmbH. The aim of the project is to develop a reliable process for thin-walled and complex CFRP components. Today, many aircraft components are made of the lightweight material CFRP. Advantages of this material are the low weight and the high stability. The processing of this material, however, is still difficult. Therefore, in order to eliminate production- and operation-related defects in a faster and more cost-efficient way, the aircraft industry requires a reliable solution.

    More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

  • Precise laser drilling of CFRP components in large quantities

    In a new joint research project, four enterprises and the Laser Zentrum Hannover e.V. (LZH) aim at further developing the laser drilling of composites for series production in the aircraft industry. Their focus is on designing an efficient system and process technique that meets the demands of aviation. Composites, such as carbon fiber reinforced plastics (CFRP), have a high potential for lightweight construction and are therefore already now widely used in aviation. These materials, however, have extraordinary properties, such as a low weight and high stability at the same time, but processing composites is quite complex. Here, mechanical processes lead to high tool wear and thus to quality problems.

    Im Rahmen von Industrie 4.0 hat die Luftfahrtbranche eine Automatisierungsoffensive gestartet. Weg von der individuell zugeschnittenen Sondermaschine für einen speziellen Prozess, hin zu universell einsetzbaren, mobilen Robotern. In dem Projekt »Prozesssichere hochproduktive Präzisionszerspanung von CFK-Großstrukturen (ProsihP II) « entwickelten deshalb Experten unterschiedlichster Disziplinen die mobile und hochpräzise Bearbeitung von CFK-Großbauteilen durch parallel arbeitende Roboter.

    Stromerzeugung aus Carbonfasern: IMH beteiligt an BMBF-Projekt

    Krefeld, 10. Februar. Die Hochschule Niederrhein erhält für das öffentlich geförderte Forschungsprojekt „Textile Kohlenstoffelektroden für mikrobielle Brennstoffzellen“ (TexKoMBZ) eine Zuwendung in Höhe von 253.000 Euro. In dem Projekt geht es darum, den Hochleistungswerkstoff Carbon, der unter anderem in der Raumfahrt genutzt wird, in Form von Fasern zur Besiedelung von stromerzeugenden Mikroorganismen einzusetzen.
