New Dimension of Structural Health Monitoring for Aircraft Components

At the ILA Berlin Air Show taking place from September 11-16, 2012, Fraunhofer Institute for Structural Durability and System Reliability LBF will present two carbon-fiber-reinforced plastic panels with integrated fiber optics (hall 3, stand 3221).
The Darmstadt-based engineers have successfully managed to develop and manufacture large CFRP parts and test them up to a load of twenty metric tons, thus launching the Institute into new dimensions of structural health monitoring.

Aviation is becoming more environmentally friendly: Innovative technologies are used to reduce fuel consumption, pollutant emissions and noise. For this purpose, Fraunhofer researchers are developing novel fuselage structures with structure-integrated functions, within the framework of the EU project "Clean Sky". The panels on display contain several sensors for the monitoring of structures; among others, acoustic sensors are applied and optical strain sensors are integrated in the panel.

Developing, manufacturing and testing prototypes made of composite fiber materials, also involving special technologies such as sensor function integration, is one of the domains of Fraunhofer LBF. In the case of the exhibits, the development chain included the design of the structure with the help of the finite-elements method (FEM), detailed construction and creation of drawings by means of CAD, the design and manufacturing of forming tools and clamping devices as well as prototype manufacturing of the panels with structure-integrated fiber-optical strain sensors and sensors for impact damage detection.

Fraunhofer LBF develops new connector solution
For the first time, an innovative connector system for fiber-optical sensors integrated in composite fiber materials, developed at Fraunhofer LBF, was implemented in a production process that came very close to series production. The panels were tested by non-destructive methods including lock-in thermography, ultrasonic and x-ray technology, as well as by destructive impact, fatigue and residual strength testing.

At the trade fair stand, Fraunhofer's engineers will show a tested and an undamaged panel. The fully functional exhibit allows visitors to try and see for themselves how the fiber-optical strain sensors react to the load to which the panel is subjected and how this is represented graphically on the screen.

Im Focus: Secure data transfer thanks to a single photon

Physicists of TU Berlin and mathematicians of MATHEON are so successful that even the prestigious journal “Nature Communications” reported on their project.

Security in data transfer is an important issue, and not only since the NSA scandal. Sometimes, however, the need for speed conflicts to a certain degree with...

Im Focus: A Light Touch May Help Animals and Robots Move on Sand and Snow

Having a light touch can make a hefty difference in how well animals and robots move across challenging granular surfaces such as snow, sand and leaf litter. Research reported October 9 in the journal Bioinspiration & Biomimetics shows how the design of appendages – whether legs or wheels – affects the ability of both robots and animals to cross weak and flowing surfaces.

Using an air fluidized bed trackway filled with poppy seeds or glass spheres, researchers at the Georgia Institute of Technology systematically varied the...

Im Focus: Reliable in-line inspections of high-strength automotive body parts within seconds

Nondestructive material testing (NDT) is a fast and effective way to analyze the quality of a product during the manufacturing process. Because defective materials can lead to malfunctioning finished products, NDT is an essential quality assurance measure, especially in the manufacture of safety-critical components such as automotive B-pillars. NDT examines the quality without damaging the component or modifying the surface of the material. At this year's Blechexpo trade fair in Stuttgart, Fraunhofer IZFP will have an exhibit that demonstrates the nondestructive testing of high-strength automotive body parts using 3MA. The measurement results are available in a matter of seconds.

To minimize vehicle weight and fuel consumption while providing the highest level of crash safety, automotive bodies are reinforced with elements made from...

Im Focus: Kick-off for a new era of precision astronomy

The MICADO camera, a first light instrument for the European Extremely Large Telescope (E-ELT), has entered a new phase in the project: by agreeing to a Memorandum of Understanding, the partners in Germany, France, the Netherlands, Austria, and Italy, have all confirmed their participation. Following this milestone, the project's transition into its preliminary design phase was approved at a kick-off meeting held in Vienna. Two weeks earlier, on September 18, the consortium and the European Southern Observatory (ESO), which is building the telescope, have signed the corresponding collaboration agreement.

As the first dedicated camera for the E-ELT, MICADO will equip the giant telescope with a capability for diffraction-limited imaging at near-infrared...

Im Focus: Locusts at the wheel: University of Graz investigates collision detector inspired by insect eyes

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.
