By: Dr.-Ing. Peter Jaeschke, Laser Zentrum Hannover e.V. The efficient use of limited resources is one of the greatest challenges of our times. To address this, lightweight solutions and concepts are already being adapted for the transportation industry, in particular within the automotive and aerospace sectors. However, in order to broaden the use of lightweight materials, there […]

Laser Cutting of CFRP Using a 30 kW Fiber Laser
By Dirk Herzog, Matthias Schmidt-Lehr, Marten Canisius, Max Oberlander, Jan-Philipp Tasche and Claus Emmelmann Today, industrial usage of Carbon Fiber Reinforced Plastic (CFRP) is steadily increasing, with an amount of 67,000 t/year. Latest products such as the Boeing 787 and Airbus A350 in the aerospace sector, as well as the BMW i3 from the automotive industry, […]
Ultra-short Pulse Laser Processing of CFRP with Kilowatt Average Power
By: Christian Freitag1,2, Margit Wiedenmann1, Jan-Philipp Negel1, André Loescher1, Volkher Onuseit1, Rudolf Weber1, Marwan Abdou Ahmed1, Thomas Graf1 In order to process Carbon fiber reinforced plastics (CFRP) with a satisfying productivity, average laser powers >1 kW are necessary. Usually high average laser powers are achieved using continuous wave (cw) laser systems but the appearance of thermal damage ranging […]
Additive Manufacturing with High-Performance Materials, Lightweight Structures by Laser Metal Deposition and Infiltration
By Frank Brueckner, Mirko Riede, Thomas Finaske, André Seidel, Steffen Nowotny, Christoph Leyens, Eckhard Beyer Laser Metal Deposition (LMD) is used for repair/redesign as well as for manufacturing of new parts. Thereby, wire or powder filler material is reabsorbed in the laser-induced melt pool resulting in a strong metallurgical bond with the subjacent substrate in combination […]
High-Efficiency Laser Processing of CFRP
By Rudolf Weber and Volkher Onuseit The benefit of CFRP for lightweight construction in automotive and airplane industries is widely accepted. Impressive pictures of high-performance cars and airplanes with numerous high-tech looking carbon fiber parts are familiar to everybody. However, industrial large-volume application of CFRP requires efficient and high-quality processing. And of course, the laser […]
