    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.

  • 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.
