Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

Nanomodified polymerstent: Novel technology for tumour therapy

  • Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.

Young Talent Award for AI supported production control of carbon fibres

  • Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

  • Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.


Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.


Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

The subject of the master's thesis was the development of a mechanism with which faulty sections in the weft yarn can be sorted out before they are woven into the textile. This way, both yarn-related weft defects and material defects can be drastically reduced. The prototype developed by Mr Zerbes shows how this can be done even during the ongoing weaving process without having to stop production. Due to its modular design, the yarn rejection unit can be retrofitted to many different types of air-jet weaving machines, which represents an enormous savings potential not only in Germany but in weaving mills all over the world.

International Sustainable Aviation and Energy Society Award for Professor Thomas Gries

On 27 November 2021, the Scientific Award for International Sustainable Aviation and Energy Society (SARES Award) was awarded to Professor Dr Thomas Gries from the Institut für Textiltechnik of RWTH Aachen University. The award ceremony took place during the closing ceremony of the International Symposium on Sustainable Aviation (ISSA) in a hybrid format online and simultaneously at Kasetsart University, Bangkok, Thailand.
 
With the award, the committee recognised the ongoing contribution of Pro-fessor Gries and the Institut für Textiltechnik to the digitisation and bio-transformation of the textile sector, as well as the Institute as a place of innovation for sustainable aviation.

On 27 November 2021, the Scientific Award for International Sustainable Aviation and Energy Society (SARES Award) was awarded to Professor Dr Thomas Gries from the Institut für Textiltechnik of RWTH Aachen University. The award ceremony took place during the closing ceremony of the International Symposium on Sustainable Aviation (ISSA) in a hybrid format online and simultaneously at Kasetsart University, Bangkok, Thailand.
 
With the award, the committee recognised the ongoing contribution of Pro-fessor Gries and the Institut für Textiltechnik to the digitisation and bio-transformation of the textile sector, as well as the Institute as a place of innovation for sustainable aviation.

Examples of this include the development of 3D braided ceramic matrix composite components for aircraft engines, which were researched together with partners in a Horizon 2020 project (EU project AllOxITD). The ongoing Chrysomallos research project as another example, funded under the national aeronautics research programme in Germany, aims to develop a completely new and sustainable high-performance insulator for aircraft cabins based on aerogels. These have a significantly lower weight than the glass fibre mats used up to now, while providing the same insulation performance, and solve the problem of the previously high manufacturing costs of aerogels. The aim of the project is to develop an insulation material with reduced density (reduction of more than 20 percent). To this end, a new type of insulation material based on aerogel is to be developed. The basis is an aerogel fleece (0.06 W/mK at 28 kg/m³), which has already been developed as part of a dissertation at the Institut für Textiltechnik of RWTH Aachen University (Mroszczok, J.: 2019).

The aviation industry is one of the fastest growing industries in the world. Due to this fact and its importance for society and the global economy, it needs to make special efforts towards sustainability. The ISSA, an international multi-disciplinary symposium, aims to address current issues in aviation such as improving aircraft fuel efficiency, promoting the use of biofuels, minimising environmental impact, mitigating greenhouse gas emissions and reducing engine and aircraft noise. ^

Through the award, SARES honours scientists and researchers whose work on sustainable aviation issues has made an important contribution at the international level. The selection is based on the scientific publications of the applicant or nominee, the h-index, i.e. the key figure for the worldwide perception of a scientist in professional circles, the project topics and the project results.

The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

Minimally invasive endovascular aortic repair (EVAR) with textile stent-graft systems is nowadays a clinically established therapy procedure for the treatment of abdominal aortic aneurysms (AAA) – pathological bulges of the aorta. Due to the thick profile of the folded stent graft systems, there is currently a high risk of injuring narrowed or highly angulated access vessels from the inside during implantation. Stent graft systems with smaller profiles could provide an improvement, which could overcome complicated access routes through a lower bending stiffness. One possible approach for reducing the system profiles is the use of thin-walled tubular woven fabrics made of ultrafine multifilament yarns (≤20 dtex) as graft material.

Up to now, it has not been possible to process the fine yarns with the required high thread density (>200 threads/cm) and the available weaving technology in order to guarantee sufficient tightness against blood.

In his master's thesis, Kai-Chieh Kuo made high-density tubular weaving of ultra-fine filament yarns possible for the first time by means of suitable modifications to a shuttle loom as well as adaptations in the weaving preparation. In particular, he developed a new innovative reed technology that reduces warp thread friction during the shedding process and thus improves the process stability of the dense tube weaving process of fine yarns.

With the help of the process modification, it was then possible to produce high-density, thin-walled tubular woven fabrics, which were positively evaluated with regard to their suitability for a stent graft. Above all the potential of these tubular fabrics lies in their extremely thin-walled fabric profile, which seals well against blood. By using these new types of tubular fabrics as graft material for stent grafts, the system profile of the folded stent graft system can be reduced without having to compromise the blood tightness of the implant. The technology developed by Mr Kuo is not only applicable to stent graft systems, but also offers great possibilities for use in all other endovascular implants such as trans catheter heart valves, covered stents and small-lumen vascular prostheses.

The Walter Reiners Foundation rewarded the doctoral thesis of Dr. Martin Hengstermann with the promotional prize in the dissertation category, endowed with 5,000 euros. The thesis deals with the production of recycled carbon fibres. These can be used to produce lightweight components for motor vehicle and aircraft construction or the wind energy sector.

New Prize Sustainability / Circular Economy
The environmental conditions of the textile industry and machine construction are changing. Topics such as climate protection and the circular economy are becoming central. From this perspective, the board of the Walter Reiners Foundation has decided to further develop the foundation's prize system.

In 2022, the foundation will for the first time offer a prize with a focus on design / sustainability. Peter D. Dornier, Chairman of the Foundation, explained: "Already in the design phase, one can set the parameters so that a textile product can be reintroduced after use into the economic cycle for a high-quality application. For example, through the appropriate use of materials and finishing. We are looking for solutions for resource-saving design, technology and manufacturing processes."

Overall prize of the “IQ Innovationspreis Mitteldeutschland“ for FibreCoat GmbH and DBF Deutsche Basalt Faser GmbH

FibreCoat GmbH from Aachen, Germany, together with DBF Deutsche Basalt GmbH, developed a completely new type of fibre material to shield electromagnetic radiation from digital end devices, medical technology or e-car batteries cheaply and effectively. The joint project was awarded the overall prize of the“ IQ Innovationspreises Mitteldeutschland“ on 24 June in an online event broadcast live from Leipzig.

The prize is endowed with €15,000 and was sponsored by the Halle-Dessau, Leipzig and East Thuringia Chambers of Industry and Commerce.

FibreCoat GmbH from Aachen, Germany, together with DBF Deutsche Basalt GmbH, developed a completely new type of fibre material to shield electromagnetic radiation from digital end devices, medical technology or e-car batteries cheaply and effectively. The joint project was awarded the overall prize of the“ IQ Innovationspreises Mitteldeutschland“ on 24 June in an online event broadcast live from Leipzig.

The prize is endowed with €15,000 and was sponsored by the Halle-Dessau, Leipzig and East Thuringia Chambers of Industry and Commerce.

Electromagnetic radiation from smartphones, hospital diagnostics and electric car batteries must be shielded so that they do not inter-fere with each other. To prevent mutual interference, they have so far been covered with metal fibre fabrics, a very time- and energy-consuming and thus expensive procedure. The new material from Basalt Faser GmbH and FibreCoat GmbH prevents this with a fibre core made of melted, thinly drawn basalt, which is coated with aluminium and bundled into the so-called AluCoat yarn. This yarn remains just as conductive and shielding, but is lighter, stronger, cheaper and more sustainable than previous alternatives. In addition, there are further advantages:

  • The number of process steps required is reduced from ten to one.
  • 1,500 metres of yarn are produced per minute instead of the previous five metres.
  • The energy required is only 10 per cent of the previous amount.

The result is a price that is twenty times lower.

The textile made of AluCoat fibres is versatile and flexible: as wallpaper it can shield 5G radiation in offices or medical rooms or encase batteries and thus ensure the smooth functioning of electric cars. AluCoat is already being used in some companies. A European fibre centre in Sangerhausen is being planned for mass production.

The two innovative companies DBF Deutsche Basalt GmbH and FibreCoat GmbH from East and West combine the two materials basalt and aluminium to protect against electromagnetic radiation. In doing so, they coat basalt with aluminium and, through this novel combination, create an inexpensive, sustainable and quickly produced alter-native for a market worth billions.

FibreCoat GmbH from Aachen is a spin-off of the Institut für Textiltechnik (ITA) of RWTH Aachen University; the managing directors Dr Robert Brüll and Alexander Lüking and Richard Haas have completed their doctorates at the ITA or are in the process of preparing their doctorates. Georgi Gogoladze, Managing Director of Deutsche Basaltfaser GmbH, also studied at RWTH Aachen University. The two managing directors Brüll and Gogoladze know each other from their student days.

From his 35 years in the composites industry with Fokker, DSM and SABIC, Warden Schijve brings a broad and deep expertise in structural design, plastics and composites, as well as processing technology.
Warden Schijve: “In my career I’ve always seen that it pays off to evaluate various different design concepts, which may use different materials or material combinations, to finally come to the most cost-competitive lightweight applications. Taking into account different manufacturing technologies right from the beginning can save a lot in later stages of component development. And this is what fascinates me about AZL and its eco-system: the available knowledge on a wide variation of process and production technologies, including cutting edge equipment, at both the AZL Tech Center, and the various institutes present in the total RWTH Aachen Campus.”

Dr. Michael Emonts, Managing Partner of AZL Aachen GmbH: "We are delighted that Warden Schijve, as a well-known face from the AZL community, will enrich us in developing lightweight applications, production systems and processes, identifying competitive technology optimizations through the analysis of markets and applications, and supporting our customers in the industrial implementation of the developed technologies."

Warden Schijve will also lead the project for a concept study for future battery casings based on composite-based multi-material systems. The AZL started the project in October together with 30 participating companies from the entire value chain to get an overview of existing component solutions, evaluate the advantages of a multi-material approach and develop a multi-material component design including a production concept for battery casings.

The Wilhelm-Lorch-Stiftung, based in Frankfurt am Main, Germany, honours a project of the Institut für Textiltechnik of RWTH Aachen University, short ITA, and awards a sponsorship prize to the ITA graduate Ricarda Wissel on 25 June 2020. She is awarded for her outstanding bachelor thesis " Implementation of elastic yarns made from carbon dioxide based thermoplastic polyurethane in socks " with funding for a subject-specific continuation of her education. The ITA receives the project sponsorship prize for the project "Smart Textiles - an interdisciplinary training course to promote young scientists in future technologies", which was submitted to the Wilhelm-Lorch-Stiftung by ITA´s PhD candidate Simon Kammler.

Carbon dioxide-based fibre from industrial waste contributes to climate protection

ITA scientist Dr.-Ing. Pavan Manvi has developed a melt spinning process at ITA for the production of elastic yarn from thermoplastic polyurethane, in which carbon dioxide is used as one of the raw materials. In her bachelor thesis, Ricarda Wissel successfully developed a process chain for the CO2-based yarn in a textile end product for the first time. In cooperation with the company FALKE and Dr Manvi, who supervised Ms. Wissel's work, the yarn was used to produce a sock (see figure "FALKE sock with carbon dioxide filaments").

By reusing carbon dioxide from industrial waste as a raw material for textile and clothing products, the carbon dioxide balance can be improved and thus contributes directly to climate protection. The sponsorship prize of the Wilhelm-Lorch-Stiftung is endowed with 6,000 € for the specialist further training of Ms. Wissel.

Interdisciplinary training with development of a new type of measuring stand for the future-oriented research field "Smart Textiles

The development of textiles with additional digital functions, so-called "Smart Textiles", is considered a future-oriented field of research. In his project submission, ITA´s doctoral candidate Simon Kammler presented a concept for a lecture series on Smart Textiles at ITA and develops a new type of measuring stand for measuring the capacity and conductivity of fibres. The project is funded by the Wilhelm-Lorch-Stiftung with a prize money of 10,000 Euro.

Smart Textiles enable the textile to interact with the environment and the human user. Today they are therefore in demand in many areas of everyday life such as sport, health, living, life and mobility and offer completely new practical solutions. In combination with digital networked services, Smart Textiles promise support and innovation in almost all situations of daily life.

With the conception of a new lecture series, Mr. Simon Kammler is supporting ITA in its goal of providing the best possible training for young scientists. The focus is on imparting far-reaching interdisciplinary skills in order to master the challenges of current fields of research.

Background:

The Wilhelm-Lorch-Stiftung supports particularly talented young people from all areas of the textile industry. Its purpose is the promotion of subject-specific education and further education as well as the promotion of projects at universities, academic schools and vocational schools, which are characterised by the sustainable communication of innovative learning content in science and research. In total, thirteen sponsorship prizes were awarded in 2020. Due to the Corona crisis, the forum of TextilWirtschaft, which is normally the venue for the awards ceremony, unfortunately had to be cancelled in 2020.

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.
