Concentrated Competencies for Non-Metals

08.11.2010
Dr. Uwe Stute is head of the new Department of Technologies for Non-Metals at the Laser Zentrum Hannover e.V. (LZH, which focuses on the thematic fields of glass, photovoltaics and composite materials.

The new Department of Technologies for Non-Metals at the Laser Zentrum Hannover e.V. (LZH) focuses on the thematic fields of glass, photovoltaics and composite materials. From basic research projects to making prototypes, this department concentrates on specific process chain solutions for industrial manufacturing.

Whether in glass processing, for the manufacturing of solar collectors, or for processing fiber-reinforced plastics, in comparison to conventional methods, the use of lasers can significantly increase quality and productivity, or even make completely new processing methods possible. For example, controlled energy input can avoid damage from thermal effects in glass components. Composites also place complex requirements on processing, due to the special characteristics of the carbon fibers.

Material damage and high wear rates for tooling composite materials can be significantly reduced using laser technology instead of the classical material removal methods. And in the field of photovoltaics, significantly higher effectivity rates for solar cells can be achieved by using selective doping, for example, which is impossible without laser technology.

By creating a new department for non-metals, the LZH would like to make a substantial contribution to innovative developments in the fields of energy generation and resource conservation. The main goals of this department include not only precise micro-machining, but also highly productive throughput optimization of large areas. The tool "laser" must be optimized in order to structure, cut, form or weld the different non-metal materials, and the laser must be integrated into complex production and manufacturing processes.

Dr. Uwe Stute is head of the new department. He has returned to the LZH after three years in industrial as a branch manager for photovoltaics. Before he started working for the firm Trumpf Laser, he was head of the Department of Production and System Technology at the LZH, from 2004 to 2008. He is excited about his return to the Hannoverian research center. "I think it is extremely interesting", he says, "to be able to work on laser processes in areas which are presently undergoing major developments. Laser technology has an enormous potential in this field."

Stute, who has a doctor's degree in physics, states that the most important current research goals of his department are to optimize glass-metal/glass-glass welding for the production of solar collectors, open new production possibilities in the field of photovoltaics using "cold" laser processing, and automating laser tooling of composite materials.

Im Focus: Making lightweight construction suitable for series production

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.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
