A scientific colloquium was held today to mark the official opening in Bremen of the new 90 cubic meter ice laboratory with integrated icing wind tunnel.
The Paint/Lacquer Technology Department at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM has thus reached a further milestone for testing anti-icing coatings and innovative deicing technologies.
Fraunhofer IFAM researchers and their project partners from industry and R&D organizations will now be able to test anti-icing systems under realistic conditions at temperatures down to minus 30 degrees Celsius and at wind speeds of up to 350 kilometers per hour.
Preventing ice forming on surfaces is a major challenge. For aircraft, ships, rail vehicles, cars, air-conditioning systems, refrigeration units, and wind turbines – ice formation often endangers safety and also incurs high costs.
Intensive R&D is underway to develop ever more effective technologies for preventing the formation and adhesive of ice on technical surfaces. Fraunhofer IFAM is investigating a variety of solution-oriented approaches and for minimizing ice formation.
These include, for example, heatable coatings and their integration into a total coating concept. The heatable coatings are suitable for all uses and can be applied using conventional spraying methods, meaning that even components with very complex geometry can be rapidly and efficiently coated.
Highly promising results have also been obtained for hydrophobic, namely water-repelling, coatings that make ice adhesion more difficult.
Nanostructured surfaces and the direct integration of freezing point depressors into the coatings themselves are other anti-icing strategies that are being pursued.
All these anti-icing concepts are undergoing thorough testing. The icing wind tunnel is equipped with special control and monitoring equipment: To get defined ice formation the water injection and air humidity can be precisely controlled.
An infrared camera simultaneously records the icing process and the heat distribution on the surfaces. The new test laboratory with icing wind tunnel will facilitate ongoing and future R&D projects and will be used for fundamental research work, ice adhesion tests, and the investigation of surface icing by snow, rain, and supercooled water droplets.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
