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.

Buildings are responsible for approximately 40% of all energy consumption and 36% of CO2 emissions in the EU. Improving energy efficiency in buildings therefore has a key role to play in achieving the ambitious goal of carbon neutrality by 2050 set out in the European Green Deal. A new briefing from the European Pultrusion Technology Association (EPTA) discusses how composite materials can help improve the thermal performance of the building envelope to satisfy increasingly stringent energy efficiency regulations. The EPTA report, Opportunities for pultruded composites in energy-efficient buildings, explains how pultruded profiles offer durable,  low maintenance solutions which can help reduce both operational and embodied carbon emissions from buildings in applications including energy-saving windows, thermal break connectors, and solar shading and cladding systems.   

“Economic and population growth mean energy demand is set to rise, making energy efficiency measures even more critical,“ comments Dr Elmar Witten, Secretary of EPTA. “Regulations and standards will continue to push for lower U-values for building elements, driving the increase use of materials and designs which minimise operational carbon emissions. Pultruded profiles offer an attractive combination of properties for designers of energy-efficient buildings – low thermal conductivity to minimise thermal bridging, together with excellent mechanical performance, durability, and design freedom.“  
 
It is estimated that today, roughly 75% of the EU building stock is energy inefficient, meaning that a large part of the energy used goes to waste. This energy loss can be minimised by improving existing buildings and striving for smart solutions and energy efficient materials for new builds. Areas of focus include improving glazing systems, better insulation of envelope components, and reducing unwanted solar heat gains. The low thermal conductivity of composites is being exploited in components and structures that help to minimise energy required for space conditioning.

• Thermal break connectors and structural assemblies
• Solar shading systems

• Batteriedeckel aus SMC – Was Composites für die Elektromobilität leisten können

Die schnelle Entwicklung der Elektromobilität hat die gesamte Werkstoffentwicklung vor neue Herausforderungen gestellt. Besonders die Batterie, ein Herzstück der Elektrofahrzeuge, stellt ausgesprochen hohe Anforderungen an die eingesetzten Materialien und Lösungen.

Bei dem Batteriegehäuse (sog. Wanne) stellen metallische Werkstoffe in Profilform (vor allem Aluminium und spezielle Stähle) bezüglich der Crashanforderungen eine etablierte Lösung dar. Bei den Batteriedeckeln stehen verschiedene Lösungen in Wettbewerb. Je nach Konzept und Hersteller werden metallische (Aluminium, bzw. Stahl) sowie nichtmetallische Werkstoffe (Kunststoffe) bzw. deren Kombinationen eingesetzt.

Welche Anforderungen werden an die potenziellen Materialien für Batteriedeckel gestellt, um in Betracht gezogen zu werden?

Dieser Artikel betrachtet vorrangig die sehr guten Verwendungsmöglichkeiten von Sheet Molding Compounds (SMC). Fünf wichtige Merkmale der Funktion eines Batteriedeckels werden nachstehend kommentiert.

1.    Mechanische Eigenschaften

Das Batteriegehäuse besteht hauptsächlich aus Aluminium – bzw. Stahlprofilen, es kann allerdings auch im Aluminiumdruckverfahren hergestellt werden. Das Gehäuse beherbergt die Zellen, die Kühlung, die Verkabelung und schützt die Batterie vor Crash - / Crush – Schäden. Außerdem ist das Gehäuse ein Teil der gesamten Fahrzeugstruktur. Für die mechanischen Anforderungen des Batteriedeckels ist faserverstärkter Kunststoff (SMC) eine passende Lösung, die folgende Vorteile bietet:

•    gute Zug – und Biegefestigkeit erhöhen die Steifigkeit,
•    SMC ermöglicht die Verteilung dieser Eigenschaften über das gesamte Bauteil,
•    Verwendung verschiedenster Fasertypen und Glaskugeln ist möglich,
•    mögliche Fasersysteme, wie uni – und multidirektionale, sowie randomisierte Schnittfasern, erhöhen die mechanischen Eigenschaften,
•    lokale Verstärkungen der Wanddicken unterstützen diese Verbesserungen und
•    stabile und vorhersehbare Eigenschaften im breiten Temperaturbereich von minus 60°C bis 150°C und darüber hinaus, keine Versprödung, kein Schmelzen bzw. Aufweichen sprechen für diesen Werkstoff.

2.    Flammwidrigkeit und Temperaturbeständigkeit

Im Falle eines Batteriebrandes hat der Insassenschutz höchste Priorität, damit die Passagiere rechtzeitig das Fahrzeug verlassen können, das Elektrofahrzeug muss den sog. 'Run away test‘ bestehen. Ein Brand kann entstehen, wenn folgende Faktoren eintreten:

•    elektrische Überladung, Kurzschluss, Fehlfunktion der Steuerelektronik
•    mechanische Einwirkungen, wie z. B. ein Crash des Fahrzeuges.

Im Brandfall können Flammen oder heiße Gase mit Temperaturen von bis zu 1100°C auftreten, die feste Partikel der Zellen beinhalten, also wie ein Sandstrahlgebläse wirken. Dünne Blechdeckel widerstehen hier nur kurzzeitig, weshalb zusätzliche Platten aus Stahl oder Geweben verwendet werden müssen, um die Sicherheitsanforderungen zu erfüllen.
SMC bietet hier folgende Vorteile:
•    die Nutzung von unterschiedlichen Füllstoffen ergeben höchste Flammwidrigkeiten,
•    durch die Verwendung von einer Faserverstärkung wird eine Formstabilität und elektrische Isolation garantiert und
•    es gibt kein Spontanversagen aufgrund von Erweichen (Thermoplaste) oder Schmelzen (Metalle).

3.     Teilegeometrie und Werkzeugkosten

Batterien aus dem Bereich der Elektromobilität haben in der Regel große Dimensionen und ein komplexes Design, um die Zellmodule, Elektronik, Verkabelung und Kühlung aufnehmen zu können. Das führt zu reliefartigen Deckelformen, die als Metallversion nur durch einen mehrstufigen Tiefziehprozess hergestellt werden können.
SMC bietet hier folgende Vorteile:
•    Herstellung mit nur einem Werkzeug,
•    Bauteilhöhen von 20mm bis 800 mm sind im gleichen Teil möglich,
•    umlaufender Rand incl. Dichtungsnut ausführbar,
•    Materialschwindung ist einstellbar und kann auch als sogenannte Null-schwinder eingestellt werden,
•    partielle Wandstärkenerhöhungen für die Flammwidrigkeit sind möglich,
•    einstufiger Herstellprozess (Fließpressverfahren).

Bei der Montage gewinnt die Geometriegenauigkeit der SMC – Deckel eine besondere Wichtigkeit, wodurch die Dichtungspressung optimiert und der fast verzugsfreie Deckel einfach montiert werden kann.
Hier ist das SMC den metallischen oder thermoplastischen Lösungen deutlich über-legen.

4.     EMV Abschirmung

Wie alle Kunststoffe, hat SMC - im Gegensatz zu Metallen - keine elektromagnetische Abschirmwirkung. Daher müssen SMC Bauteile mit einem zusätzlichen Bauteil (Blech bzw. Folie) großflächig verbunden werden, was zusätzliche Kosten verursacht. Trotzdem bleibt ein SMC- Deckel mit entsprechender Abschirmungshilfe als Systemlösung absolut funktions- und wettbewerbsfähig.

5.      Emission

Da sich die Batteriegehäuse mit dem Interieur im Karosserieinnenraum befinden, sind Anforderungen an die Emissionseigenschaften (VOC und andere) zu erfüllen. Dies stellt folgende hohen Anforderungen an:

•    die chemische Zusammensetzung des Basisharzes,
•    das sorgfältige Rezeptieren,
•    die für die Aushärtung verantwortlichen Stoffe (Initiatoren, Inhibitoren, usw.),
•    die Sauberkeit in der Halbzeugproduktion und
•    die Kontrolle des Herstellungsprozesses.

All diese Elemente sind entscheidende Voraussetzungen, um die Emissionswerte unter Kontrolle zu bringen und nachhaltig zu garantieren. Dieser Herausforderung stellt sich die SMC Industrie und hat mittlerweile bewiesen, die notwendigen Mittel und Fähigkeiten zu haben, um die geforderten Emissionswerte zu erreichen.

Das Zusammenwirken aller oben genannten Faktoren zeigt eindeutig, dass Batteriedeckel aus SMC eine technische, die Sicherheit verbessernde und wirtschaftliche Alternative zu Bauteilen aus metallischen Werkstoffen darstellen. Es handelt sich also um einen optimalen Werkstoff für die Batterielösungen der E-Mobilität, der bereits bei einigen Fahrzeugen Verwendung in der Serienproduktion gefunden hat!
