Successful SMCCreate 2023 Design Conference in Prague

With over 60 participants from Europe and the USA the second edition of the SMCCreate Design Conference took place from November 7th to 8th in Prague. The conference was jointly organized by the AVK – Federation of Reinforced Plastics and the European Alliance for SMC BMC, promoting the use of SMC and providing design tools to designers for applying these versatile materials.

During the SMCCreate 2023 conference topics covered the wide spectrum of the design with fiber composite/composite components in SMC and BMC technology, from conceptual design, development, and scale-up, with a special emphasis on recycling and sustainability solutions. 18 speakers from various European countries showed how they address important market trends and changing customer needs, and which solutions their companies offered in terms of materials, performance and much more.

As an introduction, speakers - including CTC/Airbus and Teijin - presented different possible applications for SMC and BMC components, including aircraft interiors, bicycle boxes, and applications in e-mobility. The topic of sustainability was broadly covered, highlighting recycling solutions and experiences (Siemens, IDI, OC, AOC), the use of renewable raw materials, as well new LCA models developed by the SMC BMC Alliance (LCS),

Specifically for designers, the use of the SMC flow and curing modelling was presented (ESI, OC), SMC positioning vs. aluminium (Spartners). The second day concluded with contributions on process optimization options for component production, including speeches by Dieffenbacher, Netzsch and EBG.

Die AVK – Industrievereinigung Verstärkte Kunststoffe e. V. bietet ab Dezember 2023 ein neues Seminar zur Prozesssimulation für Faserverbund-Kunststoffe an.

Prozesssimulation ist in vielen Industriebereichen nicht mehr wegzudenken und bietet auch für Faserverbundkunststoffe (FVK) enormes Potenzial. Moderne Prozesssimulationen fördern das Prozessverständnis und unterstützen die Prozess- und Werkzeugauslegung.

Die komplexen physikalischen Vorgänge, die aus der speziellen werkstofflichen Zusammensetzung von FVK resultieren, sind dabei eine Herausforderung. Die zielorientierte Auswahl und Anwendung von Simulationstechnologien erfordert ein Grundverständnis für die FVK-spezifischen Besonderheiten.

Das Seminar, das vom Simulations-Experten Dr. Miro Duhovic vom Leibniz-Institut für Verbundwerkstoffe in Kaiserslautern geleitet wird, bietet mit der grundsätzlichen Einführung in die Simulationsgrundlagen einen Einblick in die sich rasant entwickelnden Simulationsmöglichkeiten, aber auch -limitationen sowie gängige Anwendungsfälle und Aspekte der Eingangsdatengenerierung. Es wird die gesamte Bandbreite der Herstellprozesssimulationen betrachtet und am Beispiel der Resin-Transfer-Molding-Technologie ein detaillierter Einblick geboten, wobei die Teilnehmer selbst aktiv werden und ein erstes Simulations­modell mit einer Open-Source-Simulationssoftware erstellen und berechnen können.

Das erste Seminar zur Prozesssimulation findet am 5. Dezember 2023 in der AVK-Geschäftsstelle statt.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

Nachhaltigkeit, Recycling sowie E-Mobilität spielen auch bei der Herstellung und Verwendung von Composites eine immer größere Rolle und sind deshalb wichtige Themen in neuen oder bewährten Experten-Arbeitskreisen der AVK – Industrievereinigung Verstärkte Kunststoffe.

Die Themen Energiewende, Ressourcenschonung und Nachhaltigkeit sind Kernthemen des derzeitigen gesellschaftlichen und kulturellen Wandels. Die Nutzung und Schonung natürlicher Ressourcen und der Umgang mit dem Planeten Erde als Ökosystem generell sind zentrale Elemente des politischen Diskurses und halten Einzug in fast alle gesellschaftlichen und industriellen Themenbereiche. Das ökologische Bewusstsein hat in der Bevölkerung in den letzten Jahren massiv zugenommen und dieser Trend verstärkt sich auch weiterhin.

Auch Composites als Konstruktionsmaterialien und werkstoffliche Alternative zu etablierten Materialsystemen müssen sich diesen Themenbereichen stellen. Kunststoffe in all ihrer Vielfalt können, aufgrund ihrer Langlebigkeit, auch zu einem Problem werden. Hier gilt es Konzepte zu entwickeln und im industriellen Maßstab Lösungen umzusetzen. Nicht zuletzt wegen ihrer hohen Relevanz und der Aktualität nehmen entsprechende Themen in neuen, aber auch bewährten Experten-Arbeitskreisen der AVK einen breiten Raum ein.

Composites können durch ihre große Material- und Eigenschaftsvielfalt perfekt an die aktuellen Herausforderungen bei den Themen im Energie-, Automobil- und Bausektor angepasst werden. Ihre besonderen Eigenschaften haben sie vor allem in den Anwendungen bekannt gemacht, bei denen Leichtbau, Langlebigkeit, Korrosionsbeständigkeit und Wartungsarmut gefordert sind. Windkraftanlagen beispielsweise wären ohne Composites nicht denkbar.

Hervorragende Eigenschaften in der Nutzungsphase reichen heute nicht mehr aus: Konstruktionsmaterialien müssen ihre Eignung über den gesamten Lebenszyklus nachweisen. Das Thema Nachhaltigkeit wird in allen Anwendungsbereichen immer wichtiger. Neue AVK-Arbeitskreise zu Themen wie Werkstoffeigenschaften und -anforderungen für die E-Mobilität, Recycling von Composites oder auch zu Thermoplastischen Composites-Rohren zeigen, welch große Dynamik im Composites-Sektor herrscht und was für die Zukunft möglich ist.

Auch die Themen in bewährten Arbeitskreisen werden aktuell ergänzt, wie z. B. SMC-Anwendungen in der Elektro-Mobilität oder die Vorteile von pultrudierten Composites im Infrastrukturbereich. Dabei bietet auch der Leichtbau von Komponenten in den weiter auf Einsparung von Ressourcen bedachten Industriesektoren eine große Vielfalt an Einsatzmöglichkeiten für Composites. Bereits heute zeigen sich Composites auch im Hinblick auf die Nachhaltigkeit vielfach gut aufgestellt.

Die Teilnahme an den AVK-Expertenarbeitskreisen ist für Mitarbeiter von Mitgliedsunternehmen kostenlos. Mehr zu den Themen rund um die Arbeitskreise auf www.avk-tv.de
