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.

Since the completion of the human genome an important goal has been to elucidate the function of the now known proteins: a new molecular method enables the investigation of the function for thousands of proteins in parallel. Applying this new method, an international team of researchers with leading participation of the Technical University of Munich (TUM) was able to identify hundreds of previously unknown interactions among proteins.
The human genome and those of most common crops have been decoded for many years. Soon it will be possible to sequence your personal genome for less than 1000...

R2D2, a joint project to analyze and development high-TRL processes and technologies for manufacture of flexible organic light-emitting diodes (OLEDs) funded by the German Federal Ministry of Education and Research (BMBF) has been successfully completed.
In contrast to point light sources like LEDs made of inorganic semiconductor crystals, organic light-emitting diodes (OLEDs) are light-emitting surfaces. Their...

Strands of cow cartilage substitute for ink in a 3D bioprinting process that may one day create cartilage patches for worn out joints, according to a team of engineers. "Our goal is to create tissue that can be used to replace large amounts of worn out tissue or design patches," said Ibrahim T. Ozbolat, associate professor of engineering science and mechanics. "Those who have osteoarthritis in their joints suffer a lot. We need a new alternative treatment for this."
Cartilage is a good tissue to target for scale-up bioprinting because it is made up of only one cell type and has no blood vessels within the tissue. It is...
