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.

AMAC cooperates with ITA (Institute for Textile Technology of RWTH Aachen University and their ITA GmbH) for the business development in composites 

As of April 19th, 2021, AMAC is pleased to announce its cooperation with the Institute for Textile Technology, ITA, of RWTH Aachen University and their ITA GmbH. The aim of the cooperation is to strengthen and develop their business activities in composites.

ITA, as one of the largest institutes on the campus of the excellence University RWTH Aachen, Germany, develops complete solutions from the manufacturing of the fiber itself over the processing of textile intermediates with thermoplastic and thermoset resins, textile-based part manufacturing, capabilities such as braiding, pultrusion and in-situ impregnation of textile preforms. Top 3 focused industries are transportation and particularly the e-mobility sector, building and construction as well as the wind energy sector. Additionally, ITA GmbH is the partner of the industry in R&D, focusing on 8 business segments, providing technology and knowledge transfer, as well as offering comprehensive solutions along the entire textile value chain.

Prof. Dr. Thomas Gries, Director of ITA, explains the background of the strategic cooperation with focus on composites: „Our long-term experience and unmatched know-how with all aspects of continuous fibers, non-wovens and web-based reinforcements allows us to deliver to the composite manufacturers a complete technology and service offer around the development of technical textiles, from the development of glass and carbon fibers to the textile-based processing of composite parts. In all process steps of our research and developments, we focus on sustainable and recyclable solutions, an efficient cost-performance ratio, the possible use of bio-based materials and the reduction of the CO2 footprint. We are glad to cooperate with Dr. Michael Effing and AMAC in order to benefit from his door-opening network in the composites industry. “

Dr. Michael Effing, Managing Director of AMAC GmbH: „I am very happy to support the ITA to generate innovation thanks to further industrial networking and pre-competitive joint projects. ITA is indeed a one-stop source for composite solutions from the fiber to the cost-efficient manufacturing of final parts. In the context of the Covid-19 impact to the entire industry, it makes sense to bundle forces. Furthermore, ITA, with its long tradition and satisfied customers offers further valuable networking opportunities to the composites industry as well as access to relevant complementary fiber-based excellence and 250 different technologies in their machine-park with an outstanding infrastructure in Aachen.”

DFG funds Collaborative Research Centre / Transregio 280 on carbon reinforced concrete

  • Joint proposal of TUD and RWTH Aachen University

On 29 May, the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) decided to fund the Collaborative Research Centre (CRC)/Transregio 280 "Carbon reinforced concrete" at Technische Universität Dresden, short TUD, and RWTH Aachen University with the participation of the Institut für Textiltechnik, short ITA, with 12 million euros over the next four years.

The CRC/Transregio 280 “Design Strategies for Material-Minimised Carbon Reinforced Concrete Structures - Principles of a New Approach to Construction” breaks with the traditional way of designing reinforced concrete plants. The interdependence of reinforcement and matrix is being investigated in depth and a completely new design and construction strategy for building with carbon reinforced concrete is being developed.

  • Joint proposal of TUD and RWTH Aachen University

On 29 May, the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) decided to fund the Collaborative Research Centre (CRC)/Transregio 280 "Carbon reinforced concrete" at Technische Universität Dresden, short TUD, and RWTH Aachen University with the participation of the Institut für Textiltechnik, short ITA, with 12 million euros over the next four years.

The CRC/Transregio 280 “Design Strategies for Material-Minimised Carbon Reinforced Concrete Structures - Principles of a New Approach to Construction” breaks with the traditional way of designing reinforced concrete plants. The interdependence of reinforcement and matrix is being investigated in depth and a completely new design and construction strategy for building with carbon reinforced concrete is being developed.

Carbon reinforced concrete enables completely new design and construction possibilities in the building industry. The reasons for this are its very high strength and the possibility of a very low concrete overlay of only a few millimetres, as carbon, unlike structural steel, does not rust. However, the successful use of the new material, which was awarded the German Future Prize in 2016, requires completely new design and production strategies, which are being investigated in the CRC/Transregio.

Up to now, textile reinforcements have been coated and cured prior to component manufacture. This process is called offline consolidation. These stiff semi-finished products are not suitable for the production of complex components based on new, digital and continuous manufacturing processes (including 3D concrete printing and concrete extrusion). Therefore, ITA is investigating in the sub-project B02 of the CRC/Transregio how forming and consolidation steps are shifted in time by prepreg systems into the concreting process and how they can be applied within the new digital continuous manufacturing processes. In addition to established curing mechanisms, such as by heat or UV radiation, new approaches are also being researched. These new approaches include activation via the alkalinity of the concrete, microwaves and induction

The TUD and RWTH Aachen were awarded the grant on the basis of many years of experience in the research field of textile reinforced concrete. The material textile reinforced concrete was developed in two special research areas at both universities from 1999-2011 and was first fundamentally researched.

19 individual institutes are involved in the CRC/Transregio 280. The spokesman of the TUD is Professor Dr Manfred Curbach, the spokesman of the RWTH is Professor Dr Josef Hegger.
