3D printing has opened up a completely new range of possibilities. One example is the production of novel turbine buckets. However, the 3D printing process often induces internal stress in the components which can in the worst case lead to cracks. Now a research team has succeeded in using neutrons from the Technical University of Munich (TUM) research neutron source reactor for non-destructive detection of this internal stress – a key achievement for the improvement of the production processes.
Carbon fibre is an indispensable component of high-tech materials in many industries. Scientists at the University of Bayreuth are now seeking to research and develop a new generation of carbon fibre. The material is to be characterised by increased strength, remain stable even at temperatures of more than 400 degrees Celsius, and thus enable an even broader range of technological application. The German Research Foundation (DFG) will fund the project from May 2021 for the next three years to the tune of more than € 600,000.
A team of researchers at the Technical University of Munich (TUM) has developed a new early warning system for vehicles that uses artificial intelligence to learn from thousands of real traffic situations. A study of the system was carried out in cooperation with the BMW Group. The results show that, if used in today’s self-driving vehicles, it can warn seven seconds in advance against potentially critical situations that the cars cannot handle alone – with over 85% accuracy.
When a rocket is launched, the weld seams on the enormous fuel tanks must withstand immense forces. To produce joints with the necessary strength, a process known as “friction stir welding” is used. Scientists at the Technical University of Munich (TUM) are working to make this process more efficient. They are using positrons generated by the Research Neutron Source Heinz Maier-Leibnitz (FRM II) to precisely localize “atomic holes” in the material.
Unlike the classic bicycle, the handbike is powered by the arms and is one of the most popular pieces of sports equipment among paraplegics. But there's one major drawback: While on the go with a handbike, the rider has no wheelchair handy, for example to go shopping or go to a restroom. The new hybrid "BikAble" design, developed at the Technical University of Munich (TUM), combines the functions of the sports apparatus and the wheelchair.
A team led by Technical University of Munich (TUM) physicists Christoph Utschick and Prof. Rudolf Gross has succeeded in making a coil with superconducting wires capable of transmitting power on the order of more than five kilowatts contactless and with only small losses. The wide range of conceivable applications include autonomous industrial robots, medical equipment, vehicles and even aircraft.
Hof, 08.03.2021 - The high significance of digitally networked systems in the Internet of Things (IoT) has long been known in research and companies. For manufacturers, the data generated from networked systems represents a new, virtual service product with which innovative business models could be developed - if it weren't for the fact that the customers' fear of surveillance and data misuse is still so great. A new study by Prof. Dr. Christine Falkenreck (Hof University of Applied Sciences) and Prof. Dr. Ralf Wagner (University of Kassel) is now looking into the question of how customers can be involved in and convinced by new IoT business models.
Helicopters are to become faster, greener and quieter. An international team led by Airbus Helicopters (AH) is working on the technology to achieve these goals with the RACER demonstrator. Scientists from the Technical University of Munich (TUM) have designed an aerodynamically shape-optimized rotor head full fairing for the innovative RACER rotorcraft. The fairing will reduce energy consumption and make higher speeds possible.
Two-dimensional materials hold out hope for many technical applications. An international research team now has determined for the first time how strongly 2D materials vibrate when electronically excited with light.
The Manufacturing & Remanufacturing research group at the University of Bayreuth and the Fraunhofer Project Group Process Innovation, which is also based there, are pooling their expertise under the umbrella brand “Produktion.Besser.Machen.” (making production better). The aim is to support small or medium-sized enterprises in particular, so-called SMEs, in the region in becoming more future-proof, resilient, and sustainable.
