• Award for near-net-shape 3D meshes for use in fibre-reinforced plastics

As part of the JEC FORUM DACH 2022, the AVK Innovation Awards were presented in Augsburg on November 29th. The innovation price in the category "Research/Science" (first place) was awarded to the team of scientists Dipl.-Ing. Dominik Nuss, Dr.-Ing. Cornelia Sennewald and Prof. Dr.-Ing. habil. Chokri Cherif.

With the development of the pull-off-free Jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM of the TU Dresden for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. There-fore, it is now possible to produce completely new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.

Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is a unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is completely new and has never been carried out in this way before. The fabric structures are characterised by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and further more contributes to the development of completely new fields of application. The technology can be implemented on all Jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.

Professor Chokri Cherif, Institute Director of the ITM, and his team are very pleased about these continuous research success in the constantly growing research field of 3D weaving technology, which are achieved at the ITM in close cooperation with industry and users. "This award is a special honour for our institute and confirms that the many years of our excellent research in the field of near-net-shape 3D weaving for the fibre-reinforced plastics sector plays a significant role and that we are making a significant contribution to the sustainable and resource-efficient production of lightweight structures with our development".

The Mechanical Engineering Industry Association (VDMA) has awarded two prizes to graduates of the Institut für Textiltechnik (ITA) of RWTH Aachen University - the dissertation prize and the creativity prize of the Walter Reiners Foundation of German Textile Machinery 2018. ITA alumnus Dr Benjamin Weise was awarded the dissertation prize for the development of novel fibres for textile charge storage devices. For their work on a guide to 4D product design, Jan Merlin Abram and Aalon Tal (both ITA students) were honoured with the creativity prize. The dissertation prize is endowed with €5,000 whilst the creativity prize contains a one-year scholarship of €250 per month. Peter D. Dornier, President of the Walter Reiners Foundation and Chairman of the Management Board of Lindauer DORNIER, presented the awards on the 18 September 2018 at the 18th Textile Machinery Forum in the Digital Capability Center in Aachen, Germany.

Graphene revolutionizes all-in-one - supercaps, reduction of terahertz radiation and antistatics

In his dissertation "Development of graphene-modified multifilament yarns for the production of textile charge storage devices", laureate Dr Benjamin Weise developed novel fibres made of polyamide and graphene and further processed them into textile surfaces. The newly developed polyamide graphene fibres are featuring a multitude of advantages:

• Due to their high performance in the charge storage area, they are predestined for use in double-layer capacitors, so-called super capacitors, or supercaps in short. Compared to lithium-ion batteries, supercaps offer significantly higher power density and a longer lifetime as no chemical reactions are taking place. towing to the graphene platelets in the filaments, it is now possible for the first time to integrate a charge storage device directly into a textile without having to sew in a rechargeable battery. This new fibre is therefore suitable for prospective use in smart textiles, for instance in a textile defibrillator.
• The new graphene-modified polyamide fibres can attenuate inident terahertz radiation up to 25 % of their original intensity. Terahertz radiation, for example, offers transmission rates of 100 Mbit/sec and is therefore of high interest for high-performance wireless communication. However, the radiation could damage sensible electronics as in aircrafts if this technology will be used widespread. Consequently, the shielding of the radiation is of high importance, e.g. in the form of fibre composite components in the aircraft, which protect the on-board electronics.
• As the fibres are showcasing a dissipative electrical conductivity, personal protective equipment is another prospective field of application.  

The development of a pilot process for graphene-modified fibres and the production of textile demonstrators are novel and disruptive attainments of Dr Weise’s PhD thesis and the reason for the award ceremony to him. Due to its outstanding properties, the European Union is funding research on graphene within the frame of the "Graphene Flagship" with an overall budget of one billion Euro (source: http://graphene-flagship.eu/project/Pages/About-Graphene-Flagship.aspx).

Modular product design of 4D products is now possible in simplified form

How can three-dimensional products change their shape over time and thus become "four-dimensional"? The students Jan Merlin Abram and Aalon Tal provide answers to this question in their project work "Leitfaden zur Auslegung hybrider morphender Textilien am Beispiel eines Scharniers" (Guidelines for the Design of Hybrid Morphing Textiles Using the Example of a Hinge), for which they were awarded the creativity prize. In their work, the students offer a guideline for the development of a four-dimensional textile from the idea to the demonstrator. Four-dimensional textiles, for example, consist of a hybrid material of elastic textile on which three-dimensional structures are printed. The fourth dimension describes the change in shape and/or a property over a defined period of time (= morphing).  This change is caused by external influences such as light and heat.

Every year, the Foundation of the German Textile Machinery awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the smartest student research project. Further prizes were awarded to Eric Otto, ITM Dresden, and Susanne Fischer, Reutlingen University.
