Thermography on rotor blades is in the focus of the 29th webinar of the Fraunhofer Institute for Wood Research WKI on March 24, 2015. The online seminar at 2.00 p.m. will be held in english language.
Hidden defects in rotor blades of wind energy turbines can cause huge economic losses and, in the worst case of a breaking blade, threaten human lives. Consequently, the detection of structural anomalies in rotor blades should have the first priority.
Today however, most blades leave production without proper quality control. Moreover, possible damages by transport and assembly are not inspected sufficiently.
WKI's research activities have focussed on methods for detecting defects in rotor blades since many years. Of particular importance are the passive and the active infrared thermography. In such a way, defects such as delaminations, defective adhesive joints, dry laminates, ingress of moisture, but also wrinkles could be detected in many blades.
The webinar comprises the complete field of defect detection in rotor blades by means of thermography. An introduction into the technique of passive and active thermography is followed by a discussion of current problems in rotor blades and their non-destructive detection with the help of many examples.
The webinar will close with an outlook on possible future developments.

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...
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...
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...

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...
