Building lightly in an efficient manner
Together with three companies the Institute for Aircraft Construction (IFB) at the University of Stuttgart researched the automated conversion of components for aeronautical applications with a high lightweight potential, such as for example structures of aircraft seats or reinforcements of window frames.
The efficiency of the automation process as well as the quality and functionality of the products resulting from this is to be increased through a number of further developments. The objective of the project going by the name of “3D TFP“ is the material-efficient manufacturing of the products as well as a sustainable reduction in CO2 emissions in flight operations.
In order to achieve this, the partners use a manufacturing process with which the expensive carbon fibres can be arranged almost without offcuts and with a good load-bearing capacity in the component (Tailored Fibre Placement, in brief TFP process). Since an effective and to date quick deposit of the fibres has only been possible on the flat side, a reliable method to convert these semi-finished products is to be developed into a complex 3D structure.
The focus thereby is an automated and resource-efficient production of aeronautical components that on the one hand reduces the process tolerances and on the other hand the overall process costs. With this the door to production would be opened in a high-wage country like Germany. Furthermore, the scientists wish to integrate additional functions such as, for example conductive or sensory elements in the component. These added values are to justify the higher manufacturing costs compared to the classic metal construction and increase the market opportunities of the end product.
Alongside the IFB at the University of Stuttgart as the main developer, the consortium comprises the manufacturer of aircraft seats RECARO Aircraft Seating in Schwäbisch Hall, the synthetic resin manufacturer Sika Deutschland in Bad Urach and the process automation supplier Siemens from Stuttgart. Within three years the partners jointly intend to press ahead with the automated manufacturing of low cut-off waste semi-finished products to manufacture lightweight parts from fibre plastic composites. The project is being funded with a sum of 321,000.- Euros by the State of Baden-Württemberg in the framework of the strategy for the lightweight construction.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
