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.

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...
