• Flame Retardancy for Composites Applications in the Transport Sector

On 10-11 May 2023, the AVK - Industrievereinigung Verstärkte Kunststoffe e. V. in cooperation with the FGK - Forschungsgesellschaft Kunststoffe e.V. in Berlin organised for the first time an international, English-language conference on flame retardancy.

In 18 compact lectures, more than 20 experts informed nearly 80 participants about new developments, requirements and innovations regarding specific flame retardant properties of components made of fibre-reinforced plastics/composites for the transport sector.

Among others, there were presentations by industry representatives from Saertex, BÜFA, Clariant, Diehl Aviation and Airbus, but also from institutes such as the Fraunhofer Institutes or the Federal Institute for Materials Research and Testing. Presentations on the topics of standardisation, raw materials, automotive or recycling were on the agenda, but also flame retardants for connectors and battery housings for electric vehicles or fire-retardant systems for rail vehicles or fire-retardant CFRP made from recycled CF nonwoven were presented.

The international association that will manage the Single-Entry-Point (SEP) of the BIONANOPOLYS project has been formally constituted and will be able to support companies across the European Union in the market introduction of bionanomaterials through technical, legal, regulatory, safety, economic and financial support services.

The SEP was established as an AISBL (non-profit entity) on 17 February 2023 in the framework of the European project BIONANOPOLYS, funded by the Horizon 2020 programme. The technical director of ITENE and coordinator of this project, Carmen Sánchez, is the president of this association in which representatives of other project partners also act as directors. Specifically, the CTP (Centre Technique du Papier) from France; CIDAUT (Fundación para la Investigación y Desarrollo en Transporte y Energía), from Spain; CENTI (Centre for Nanotechnology and Smart Materials), from Portugal, and the law firm Gil & Robles - San Bartolome & Associés, from Luxembourg.

The BIONANOPOLYS SEP will reduce the risks and barriers to the commercial exploitation of bio-based materials and polymeric bionanocomposites with nanotechnology and accelerate market penetration and innovation processes. SMEs, large companies, and potential customers who are users of the BIONANOPOLYS OITB (Open Innovation Test Bed) will be able to access the services offered by the project partners through this entity, which will act as a one-stop shop, at affordable costs and conditions.

The test bed consists of 14 enhanced pilot plants and complementary services to support technological and commercial breakthroughs. Collaboration between all the partners that make up BIONANOPOLYS and access through the SEP allows joint access to all the services offered by the partners and helps to drive collaborative open innovation.

Call for access to the BIONANOPOLYS OITB
The SEP and the project partners will be in charge of evaluating the projects submitted to the BIONANOPOLYS platform once the open call launched last February to select five projects from different European countries that will be able to access its services free of charge to develop, test or scale-up bionanomaterials in the BIONANOPOLYS OITB closes.

Companies wishing to access the services to develop or test nanomaterials can submit their applications until 30 April.

The BIONANOPOLYS test bed could benefit companies involved in the production of biopolymers, cellulose paper, nonwovens, foams, or coatings, as well as the packaging, agriculture, food, cosmetics, pharmaceuticals, hygiene, textiles and 3D printing sectors.

In recognition of his extraordinary engineering achievements in the fields of textile mechanical engineering, textile technology as well as textile chemistry and surface modification of textile semi-finished products, Prof. Paul Kiekens was awarded the title of Doctor honoris causa (Dr.-Ing. h.c.) on April 5, 2023.
 
Prof. Kiekens was a university professor at Ghent University, Belgium, for almost 35 years and thus responsible for textile-oriented education and research. Intensive interaction with European business and science was always particularly important to him.
 
Immediately after the fall of the Berlin Wall, he opened the way for international cooperation in teaching and research in the field of textile mechanical engineering, textile technologies, and textile chemistry for the only Eastern European university research institution with a textile orientation, the ITM (formerly ITB) at the Faculty of Mechanical Engineering of TU Dresden, and provided great and uncomplicated support. A close, lasting and intensive relationship developed, which had a trend-setting influence on the scientific career of Professor Paul Kiekens. This was reflected above all in the expert advice given for major projects.
 
These include, for example, the funded junior research group "Holistic approach to the development and modelling of a new generation of multiaxial fabrics for fibre composites to strengthen Saxon, French and Flemish industry in the high-performance sector" (SAXOMAX) and jointly acquiring the EU project "Large scale manufacturing technology for high performance lightweight 3D multifunctional composites" (3D-LightTrans). Especially in these large-scale projects, intensive cooperation with industrial partners was essential for success.
 
As early as the 1990s, Professor Paul Kiekens had the vision of creating a European network for universities in textile teaching and research. In 1994, the Association of Universities for Textiles (AUTEX) was founded with the aim of establishing teaching and research in the field of textile technology at an internationally respected level through joint concepts. Due to the prevailing cooperation at that time between Professor Dr. Paul Kiekens and Professor Dr. Peter Offermann, the TU Dresden, represented by the ITM (formerly ITB), has been a full member and decisively integrated in the network since its foundation on July 1, 1994. Thus Prof. Dr.-Ing. habil. Paul Kiekens has significantly promoted the international cooperation of the TU Dresden, Faculty of Mechanical Engineering with international university textile research institutions.
 
Professor Paul Kiekens was executive coordinator of AUTEX until his retirement. The internationally renowned symposium takes place annually as a part of AUTEX.

Freudenberg Performance Materials (Freudenberg) will present surfacing veils and core materials for lightweight fiber reinforced plastic (FRP) parts at JEC in Paris, France. Freudenberg will also be showcasing Enka® Solutions flow media and spacers for efficient vacuum infusion, resin transfer and foam injection molding processes for applications in the composites industry, etc. at the international composites show.
 
Freudenberg’s solutions for the FRP industry include a variety of glass, PAN and PET nonwovens, as well as core materials for the production of lightweight fiber reinforced plastic parts. These products are designed for anti-corrosion coatings in piping and tank construction, smooth UV resistant surfaces for facade panels, and other applications for a diverse range of end products. Products made from fiber reinforced plastics must be equipped with surfacing veils to provide abrasion resistance, corrosion resistance, smooth surfaces and mechanical strength. Freudenberg offers high-tech nonwovens that can meet these challenges.
 
Enka® Solutions products are characterized by their typical 3D entangled polymeric filament structures. Thanks to this structure, they are exceptionally suitable as flow media and spacers when producing composite materials.

The AVK Working Group SMC/BMC and the European Alliance for SMC BMC are jointly organising SMCCreate 2023 - a conference on designing with SMC and BMC composites. The event, which offers insights into the entire product design process from idea to part manufacture, is aimed at both experienced designers and those new to the use of these materials.

Around 60 participants from all over Europe attended the first SMCCreate design conference, which took place in Antwerp in June 2022. SMCCREATE 2023 will take place in Prague (Czech Republic) on 7-8 November 2023 at the Vienna House by Wyndham Diplomat Prague; conference language is English. After a successful launch, AVK and the European Alliance for SMC BMC are looking forward to the second edition of the event and invite speakers to apply with their presentation proposals by 27 February. (Mail address: info@avk-tv.de).

The aim of the conference is to help designers and engineers choose the best material solution for their applications. Presentations will focus on best practices and industrial solutions, SMC and BMC component manufacturing, material selection and product development throughout the product life cycle, from design to sustainability.

Society and the economy are facing existential challenges. In addition to the consequences of climate change, these include the realisation that energy and many resources are no longer available in the usual quantities, so that their efficiency must be significantly increased in the short term. Lightweight construction, especially with fibre composite materials, can and will make an important contribution here, e.g. in wind power plants or hydrogen storage systems. As an umbrella organisation, Composites Germany represents the capabilities and interests of the German fibre composite industry. With the re-entry of Composites United, Composites Germany will combine the forces of the two leading composites networks in Germany and its position will be significantly strengthened. Changed framework conditions make the re-entry possible and necessary.

VDMA and Leichtbau BW will continue to support the work of Composites Germany as associate members and contribute the know-how of their members. Together, the organisations will promote sustainable lightweight construction as a key technology for Germany, focusing on composites materials, says Prof. Klaus Drechsler of Composites United, one of the two board members of Composites Germany. As a network and mouthpiece of the composites industry, Composites Germany bundles the interests of its members. The aim is to continuously expand activities, promote innovations and technologies, develop new markets and new value chains, and anchor training and further education, adds his board colleague Dr Michael Effing of AVK. The agreement was concluded on 29 November 2022 during the JEC Forum DACH in Augsburg, where both associations were cooperation partners of the event.

Im Automobilbau, dem Schiffsbau und der Luftfahrtindustrie sowie bei Windenergieanlagen steigen die Materialanforderungen zusehends. Die verwendeten Werkstoffe sollen leicht, ressourcenschonend und gleichzeitig hochbelastbar sein. Faserverstärkte Kunststoffe (Composites) rücken immer mehr in den Vordergrund, da deren Eigenschaften in Kombination mit Glas- oder Carbonfasern metallischen Materialien oftmals überlegen sind. Mit Fokus auf die klimaneutrale Herstellung und Nutzung von Produkten wächst auch der Bedarf an Recyclinglösungen. Im SmartERZ-Projekt TRICYCLE arbeiten Unternehmen gemeinsam an geeigneten skalierbaren und wirtschaftlich tragfähigen Prozessen zum Recycling von Smart Composites. Momentan gibt es dafür keine Anbieter oder Konzepte am Markt.

Smart Composites bestehen aus Werkstoffen, deren Funktionalisierung durch die Integration oder Applikation elektrisch leitfähiger Komponenten, z. B. Sensoren oder Mikroprozessoren, erreicht wird. Dazu zählen zum Beispiel smarte Textilien, die elektronisch wärmen, Lichtsignale geben oder zur Datenübertragung genutzt werden können. Das breite Anwendungsspektrum und die vielseitigen Einsatzgebiete dieser intelligenten Verbundwerkstoffe und Multimaterialverbunde werden perspektivisch zu einem wachsenden Bedarf und einer stärkeren Nachfrage führen.

Die funktionale und vielschichtige Verbindung verschiedener Materialien wie Kunststoff, Metall und Textil wirft beim Thema Recycling Nachhaltigkeitsfragen auf. Im Erzgebirge werden dafür bereits heute Lösungen entwickelt. Im Rahmen des WIR!-Projektes SmartERZ ist das Verbundprojekt TRICYCLE entstanden. Mit dem Fokus auf den Strukturwandel im Erzgebirge haben sich acht ortsansässige Partner aus Wissenschaft und Wirtschaft zusammengetan, um ein Recyclingkonzept aufzustellen und die Grobplanung für ein erzgebirgisches Recycling Center zu entwickeln. Das Ende des Produktlebenszyklus und die Nachnutzung bzw. Wiederaufbereitung stehen dabei im Mittelpunkt des Entwicklungsprozesses. Im Ergebnis sollen effektive und maßgeschneiderte Maßnahmen für eine möglichst hochwertige Wiederverwendung entstehen. Diese sollen dem steigenden Aufkommen an Abfällen aus diesem wachsenden Bereich der deutschen Industrie begegnen und anwendungsbereit sein.

Klassische Herausforderungen für die Projektbeteiligten sind die irreversiblen Verbindungstechniken (z. B. Kleben, Faser-Matrix-Haftung), die Integration vieler verschiedener Materialien in geringen Mengen sowie Form und Größe der Bauteile. Eigene Untersuchungen sowie Feedback von Partnerunternehmen bestätigen die Notwendigkeit sowie den Nutzen eines passgenauen Recyclingprozesses für Smart Composites und intelligente Multimaterialverbünde. Das Projekt soll dazu beitragen, den Wirtschaftsstandort Erzgebirge attraktiver und zukunftsfähiger zu gestalten.

Am 1. September 2021 gestartet, kann TRICYCLE erste Ergebnisse vorweisen. Zunächst wurden die Bedarfe bei mittelständischen Unternehmen in der Region Erzgebirge abgefragt, um die aktuellen Gegebenheiten und den Status quo in Bezug auf technologische Recyclingkonzepte bestmöglich abzubilden. Für ein fundiertes Recyclingkonzept hat das TRICYCLE-Team drei Referenzbauteile für den vorgesehenen Prozess ermittelt, die in der erzgebirgischen Wirtschaft Verwendung finden, und folgenden Bereichen zugeordnet: Automotive, Technische Textilien mit applizierter Zusatzfunktion und Technische Textilien mit integrierter Zusatzfunktion.

Basierend auf dieser Auswahl, analysiert das Projektteam momentan die Herstellungs- und bisherigen Recyclingprozesse der Referenzbauteile. Das beinhaltet auch die Planung praktischer Versuche zum Recycling. Dabei fokussieren sich die Projektpartner auf ihr Know-how in verschiedenen chemischen, thermischen und mechanischen Prozessen zur Separierung, Rückführung und Wiederverwendung der eingesetzten Materialien. Um die Produkte den Recyclingtechnologien zugänglich zu machen, wurde die Herangehensweise innerhalb des Projekts angepasst, da insbesondere Textil aufgrund von Form und Struktur (z. B. endlose Struktur) herausfordernd sein kann.

Obwohl die Materialien selbst recycelbar sind, müssen diese dennoch für den Prozess optimal vorbereitet bzw. fachgerecht aufbereitet werden. Die Expertise und die Technologiekompetenz, die hierfür benötigt werden, ist bei den beteiligten Projektpartnern durch jahrzehntelange Erfahrung und zahlreiche Innovationen vorhanden. Das Zusammenspiel aller Beteiligten im Projekt TRICYCLE stellt bereits jetzt die Weichen für das geplante Recycling Center, um dieses später zum Drehkreuz zwischen regionalen Produktionsunternehmen und dem Recycling weiterzuentwickeln. Dieses soll als „Open Factory“ aufgebaut werden, um den Unternehmen des SmartERZ-Bündnisses bzw. perspektivisch der Region Erzgebirge eine gemeinsame Nutzung zu ermöglichen.

„Die Wiederverwendung der eingesetzten Ressourcen ist sowohl aus ökonomischer als auch aus ökologischer Sicht zwingend geboten. Momentan gibt es weder Anlagenbauer noch Dienstleistungsanbieter mit den entsprechenden Kompetenzen zum Recycling von Smart Composites oder Multimaterialverbünden am Markt,“ stellt Johannes Leis, der Verbundkoordinator vom Sächsischen Textilforschungsinstitut e.V. (STFI) in Chemnitz fest.Unter Leitung des STFI als Verbundkoordinator mit seiner über 30-jährigen Erfahrung in der Textilbranche und speziellem Know-how im Recycling von Carbonabfällen haben sich weitere Unternehmen und Forschungseinrichtungen zusammengefunden. Dazu zählen das Textilunternehmen Curt Bauer GmbH, die Professur Fabrikplanung und Fabrikbetrieb der TU Chemnitz, das Ingenieurbüro Matthias Weißflog, der Hersteller für Faserverbundbauteile Cotesa GmbH, der Spezialvlieshersteller Norafin Industries (Germany) GmbH, das Recyclingunternehmen Becker Umweltdienste GmbH und die Hörmann Rawema Engineering & Consulting GmbH. Am Ende der Projektlaufzeit sollen ein einsatzfähiges, technologisches Recyclingkonzept für die zukünftigen entstehenden smarten Produkte sowie die in der Produktion entstehenden Abfälle (bspw. durch fehlerhafte Bauteile und Randbeschnitte) und ein Konzept für den Aufbau eines Recycling Centers vorliegen, das im Erzgebirge entstehen soll.
