New Dimension of Structural Health Monitoring for Aircraft Components

10.09.2012
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: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
