Teijin Carbon produces new thermoplastic PPS-Tape

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.

SGL Carbon and Koller Kunststofftechnik manufacture composite windshield for BMW Group

  • Carbon fibers combined with injection molding replace conventional steel construction
  • SGL Carbon supplies innovative carbon fiber profiles
  • Serial use in a future high-volume model of BMW Group
  • Construction method offers great potential for use in other automotive projects

Already in August, SGL Carbon received a multi-year order from Koller Kunststofftechnik GmbH for the production of novel carbon fiber profiles for serial use in windshields for a future high-volume model of BMW Group.

The profiles are particularly flexible fiber tows, pre-impregnated with thermoplastic resin in various dimensions. They will be compiled by SGL Carbon on the basis of its own 50k carbon fiber at its site in Innkreis, Austria, and subsequently processed by the injection molding experts at Koller to form a skeletal plastic component. The composite component will replace the previous steel-based windshield. Production of the carbon fiber profiles will start in the remainder of 2020 and will then be ramped up gradually over the next few years for the BMW Group model launch.

The composite component will replace the previous steel-based windshield. Production of the carbon fiber profiles will start in the remainder of 2020 and will then be ramped up gradually over the next few years for the BMW Group model launch.

In the vehicle, the windshield is a connecting element between the roof frames and thus has an important stabilizing function. The carbon fiber profiles add the required stiffness and crash safety to the component. At the same time, they help to significantly reduce the weight of the roof and thus also support the driving dynamics. The injection molding process also enables particularly complex and material-efficient structures. In the BMW Group model, this innovative component concept will cut weight by 40 percent compared to conventional steel designs of the component while creating important space for cable ducts and sensors.

The production of the carbon fiber profiles themselves is also particularly geared to material and process efficiency in large-scale production. The profiles consist of several smaller fiber strands, the so-called rods, and are manufactured using the modern continuous pultrusion process. During product and process development it was one key objective to ensure that material loss during production is almost completely avoided.

"At SGL Carbon, we have been working on the development of thermoplastic carbon fiber profiles for use in injection molding for some time already. This development work is now beginning to pay off. Due to the many advantages and competitive costs, we see a great potential for the technology to be used in other automotive projects too," explains Sebastian Grasser, Head of the Automotive Segment in the Business Unit Composites - Fibers & Materials at SGL Carbon.

"Innovative lightweight construction with hybrid designs has developed into a strategically conclusive concept for Koller Group's OEM customers," confirms Max Koller, CEO of Koller Group. "SGL Carbon's high level of material expertise, combined with the process know-how of KOLLER Kunststofftechnik and KOLLER Formenbau, create the basis for a promising future in innovative lightweight construction technologies. With this order, the BMW Group has confirmed its confidence in the successful cooperation between SGL and Koller; we are particularly pleased about this", said Max Koller.
 
The Koller Group is a globally operating technology company with plants in Europe and China, as well as NAFTA. The Koller Group develops and manufactures lightweight construction, tools and serial components, primarily for the automotive industry.

Oerlikon: Robust pumps for sophisticated special fibers

At first glance, rowing boats, the Airbus 380, safety equipment and stadium roofing have very little on common. They receive their specific properties as a result of the use of special fibers, among other things: aramid fibers and carbon fibers are processed into special yarns that are frequently deployed as compound materials. These fibers are growing in demand as the world seeks to reduce its reliance on fossil fuels; new solutions are required to reduce weight and replace heavy metallic parts.

Aramid fibers are produced in a highly-chemical process that is extremely aggressive; the acrylic precursor used to manufacture carbon fibers is a different process, but again no less difficult. In these sophisticated processes, the gear metering pumps are not only responsible for the high-precision control of the melt transport; durability, resistance within aggressive environments and cost efficiency also play decisive roles.

Special materials for special tasks
The process, the expected pump lifespan and the maintenance frequency are the decisive factors for choosing the materials from which the pumps and their components are manufactured. For optimum results, Oerlikon Barmag offers solutions that intelligently combine the various materials and the latest technologies. Whether in the case of surfaces with ceramic coatings, gears and shafts featuring DLC coatings, pumps made from cobalt alloys (StelliteTM) or robust and durable Oerlikon Barmag hybrid constructions comprising zirconium oxide ceramic and duplex stainless steel – the high-precision ZP- and GM-series pumps are design-optimized depending on the intended use. Various seal systems and customized drive concepts round off the pump program.

Innovationen beim Recycling von Carbonfasern

  • Kohlenstoff mit mehreren Leben

Geht es um die Zukunft der motorisierten Mobilität, reden alle vom Antrieb: Wie viel E-Auto, wie viel Verbrenner verträgt die Umwelt und braucht der Mensch? Zugleich stellen neue Antriebe erhöhte Anforderungen nicht nur an den Motor, sondern auch an dessen Gehäuse und die Karosse: Für solch anspruchsvolle Anwendungen kommen häufig Carbonfasern zum Einsatz. Wie der Antrieb der Zukunft, sollten auch die Werkstoffe am Fahrzeug umweltfreundlich sein. Deshalb ist Recycling von Carbonfasern gefragt. Lösungen dafür haben Institute der Zuse-Gemeinschaft entwickelt.

  • Kohlenstoff mit mehreren Leben

Geht es um die Zukunft der motorisierten Mobilität, reden alle vom Antrieb: Wie viel E-Auto, wie viel Verbrenner verträgt die Umwelt und braucht der Mensch? Zugleich stellen neue Antriebe erhöhte Anforderungen nicht nur an den Motor, sondern auch an dessen Gehäuse und die Karosse: Für solch anspruchsvolle Anwendungen kommen häufig Carbonfasern zum Einsatz. Wie der Antrieb der Zukunft, sollten auch die Werkstoffe am Fahrzeug umweltfreundlich sein. Deshalb ist Recycling von Carbonfasern gefragt. Lösungen dafür haben Institute der Zuse-Gemeinschaft entwickelt.

Carbonfasern, auch als Kohlenstofffasern oder verkürzt als Kohlefasern bekannt, bestehen fast vollständig aus reinem Kohlenstoff. Sehr energieaufwändig wird er bei 1.300 Grad Celsius aus dem Kunststoff Polyacrylnitril gewonnen. Die Vorteile der Carbonfasern: Sie haben kaum Eigengewicht, sind enorm bruchfest und stabil. Solche Eigenschaften benötigt man z.B. am Batteriekasten von E-Mobilen oder in Strukturbauteilen der Karosserie. So arbeitet das Sächsische Textilforschungsinstitut e.V. (STFI) aktuell gemeinsam mit Industriepartnern daran, statisch-mechanische Stärken der Carbonfasern mit Eigenschaften zur Schwingungsdämpfung zu verknüpfen, um die Gehäuse von E-Motoren im Auto zu verbessern. Angedacht ist in dem vom Bundeswirtschaftsministerium geförderten Projekt die Entwicklung sogenannter Hybridvliesstoffe, die neben der Carbonfaser als Verstärkung weitere Faserstoffe enthalten. „Wir wollen, die Vorteile unterschiedlicher Faserstoffe verbinden und so ein optimal auf die Anforderungen abgestimmtes Produkt entwickeln“, erläutert Marcel Hofmann, STFI-Abteilungsleiter Textiler Leichtbau.

Damit würden die Chemnitzer Forschenden bisherige Vliesstoff-Lösungen ergänzen. Sie blicken auf eine 15-jährige Geschichte in der Arbeit mit recycelten Carbonfasern zurück. Der globale Jahresbedarf der hochwertigen Fasern hat sich im vergangenen Jahrzehnt fast vervierfacht, laut Angaben der Industrievereinigung AVK auf zuletzt rd. 142.000 t. „Die steigende Nachfrage hat das Recycling immer stärker in den Fokus gerückt“, betont Hofmann. Carbonfaserabfälle sind ihm zufolge für etwa ein Zehntel bis ein Fünftel des Preises von Primärfasern erhältlich, müssen aber noch aufbereitet werden. Dreh- und Angelpunkt für den Forschungserfolg der recycelten Fasern sind konkurrenzfähige Anwendungen. Die hat das STFI nicht nur am Auto, sondern auch im Sport-Freizeitsektor sowie in der Medizintechnik gefunden, so in Komponenten für Computertomographen. "Während Metalle oder Glasfasern als potenzielle Konkurrenzprodukte Schatten werfen, stört Carbon die Bilddarstellung nicht und kann seine Vorteile voll ausspielen“, erläutert Hofmann.

Papier-Knowhow nutzen
Können recycelte Carbonfasern nochmals den Produktkreislauf durchlaufen, verbessert das ihre CO2-Bilanz deutlich. Zugleich gilt: Je kürzer die Carbonfasern, desto unattraktiver sind sie für die weitere Verwertung. Vor diesem Hintergrund entwickelten das Forschungsinstitut Cetex und die Papiertechnische Stiftung (PTS), beide Mitglieder der Zuse-Gemeinschaft, im Rahmen eines Forschungsvorhabens ein neues Verfahren, das bislang wenig geeignet erscheinende Recycling-Carbonfasern ein zweites Produktleben gibt. „Während klassische Textilverfahren die ohnehin sehr spröden Recycling-Carbonfasern in Faserlängen von mind. 80 mm trocken verarbeiten, beschäftigten wir uns mit einem Verfahren aus der Papierindustrie, welches die Materialien nass verarbeitet. Am Ende des Prozesses erhielten wir, stark vereinfacht gesprochen, eine flächige Matte aus recycelten Carbonfasern und Kunststofffasern“, erläutert Cetex-Projektingenieur Johannes Tietze das Verfahren, mit dem auch 40 mm kurze Carbonfasern zu attraktiven Zwischenprodukten recycelt werden können. Das danach in einem Heißpressprozess entstandene Erzeugnis dient als Grundmaterial für hochbelastbare Strukturbauteile. Zusätzlich wurden die mechanischen Eigenschaften der Halbzeuge durch die Kombination mit endlosfaserverstärkten Tapes verbessert. Das Recyclingprodukt soll, so die Erwartung der Forschenden, glasfaserverstärkten Kunststoffen, Konkurrenz machen, z.B. bei Anwendungen im Schienen- und Fahrzeugbau. Die Ergebnisse fließen nun in weiterführende Forschung und Entwicklung im Kooperationsnetzwerk Ressourcetex ein, einem geförderten Verbund von 18 Partnern aus Industrie und Wissenschaft.

Erfolgreiche Umsetzung in der Autoindustrie
Industriereife Lösungen für die Verwertung von Carbonfaser-Produktionsabfällen werden im Thüringischen Institut für Textil- und Kunststoff-Forschung Rudolstadt (TITK) entwickelt. Mehrere dieser Entwicklungen wurden mit Partnern beim Unternehmen SGL Composites in Wackersdorf industriell umgesetzt. Die Aufbereitung der so genannten trockenen Abfälle, hauptsächlich aus Verschnittresten, erfolgt nach einem eigenen Verfahren. „Dabei führen wir die geöffneten Fasern verschiedenen Prozessen zur Vliesherstellung zu“, sagt die zuständige Abteilungsleiterin im TITK, Dr. Renate Lützkendorf. Neben den Entwicklungen für den Einsatz z.B. im BMW i3 in Dach oder Hintersitzschale wurden im TITK spezielle Vliesstoffe und Verfahren für die Herstellung von Sheet Molding Compounds (SMC) etabliert, das sind duroplastische Werkstoffe, die aus Reaktionsharzen und Verstärkungsfasern bestehen und zum Pressen von Faser-Kunststoff-Verbunden verwendet werden. Eingang fand dies z.B. in einem Bauteil für die C-Säule des 7er BMW. „In seinen Projekten setzt das TITK vor allem auf die Entwicklung leistungsfähigerer Prozesse und kombinierter Verfahren, um den Carbonfaser-Recyclingmaterialien auch von den Kosten her bessere Chancen in Leichtbauanwendungen einzuräumen“, betont Lützkendorf. So liege der Fokus gegenwärtig auf dem Einsatz von CF-Recyclingfasern in thermoplastischen Prozessen zur Platten- und Profilextrusion. „Ziel ist es, die Kombination von Kurz- und Endlosfaserverstärkung in einem einzigen, leistungsfähigen Prozess-Schritt zu realisieren.“

Materials made of composites are suited for battery enclosures for different reasons: Besides their light weight, which enhances the electric vehicle’s range, fiber-reinforced plastics offer high stiffness. In addition, they meet high requirements for water and gas tightness and feature excellent fire protection properties. Composite materials can also help to achieve improved structural stiffness of the underbody, e.g. to protect against penetration, as well as an optimized thermal management. Carbon fibers are ideal for especially stressed structures or load-bearing elements, such as the underbody panels and side frames. For components subjected to less stress, such as battery box covers, glass fibers or a fiber mix may suffice.

In addition to the new application for the hybrid model battery enclosure, SGL Carbon will continue producing the usual components made of carbon-fiber-reinforced plastic for the BMW i3 and delivering materials for the Carbon Core body of the BMW 7 series, and has been nominated as the supplier for all carbon materials - fibers, textiles, stacks - for the BMW iNEXT, set to be launched in 2021.

Automotive Innovations

Hexcel’s carbon prepreg patch technology provides an innovative way of locally stiffening and reinforcing metal parts, providing noise and vibration management functionality. HexPly® prepreg patches consist of unidirectional carbon fiber impregnated with a fast curing epoxy matrix that has self-adhesive properties, enabling it to bond to metal in a highly efficient one-step process. These key technology properties are demonstrated in an 18.5kg aluminum subframe (that is 50% lighter than steel equivalents), which was reinforced with 500 grams of HexPly® prepreg and tested by Saint Jean Industries. The part demonstrates a significant reduction in noise, vibration and harshness (NVH). Other benefits include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. With this technology Hexcel is a finalist in the JEC Innovation Awards 2019 in the Automotive Applications category.

HexPly® prepreg patch technology was also applied to a hybrid side sill demonstrator developed with Volkswagen and Dresden University to address future crash test requirements, specifically for electric cars. Combining fiber-reinforced plastic (FRP) with metal, the hybrid construction allows for optimum performance including weight savings, enhanced safety, increased energy absorption, battery protection in a crash situation and production flexibility.

Hexcel will also display a lightweight CFRP transmission crossmember produced from Hexcel’s high performance HexMC®-i 2000 molding compound. The transmission crossmember was developed in partnership with the Institute of Polymer Product Engineering (at Linz University), Engel and Alpex. As the part connects the chassis together and supports transmission it has to be stiff and strong, resisting fatigue and corrosion. Hexcel’s HexMC®-i 2000 was selected as the best-performing molding compound on the market, curing in as little as two minutes to produce lightweight, strong and stiff parts.
To produce the transmission crossmember HexMC®-i 2000 preforms are laid up in Alpex molds and compression-molded in a v-duo press that was tailored for the application by Engel. Ribs, aluminum inserts and other functions can be molded into the part using the single-stage process, reducing component-count. Any offcuts from the preforms can be interleaved between the plies of material to provide additional reinforcement in key areas - meaning that the process generates no waste.

Other Automotive promotions on Hexcel’s stand at JEC World include a composite leaf spring manufactured by ZF using HexPly® M901 prepreg. In contrast to steel leaf springs, composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. HexPly® M901 prepreg reduces the cure cycle to below 15 minutes and provides 15% higher mechanical performance, with enhanced fatigue properties. It also operates at high temperatures, providing a Tg of up to 200°C following a post cure.

Marine Innovations

Hexcel has a comprehensive range of products aimed at racing yacht and luxury boat builders that include America’s Cup, IMOCA class and DNV GL-approved prepregs, woven reinforcements and multiaxial fabrics for hull and deck structures, masts and appendages.

At JEC World Hexcel will display an IMOCA yacht mast manufactured by Lorima using HexPly® high modulus and high strength carbon fiber prepreg from Hexcel Vert-Le-Petit. Lorima is the exclusive official supplier of masts for IMOCA 60 class racing boats.

Hexcel’s HexTow® IM8 carbon fiber has been selected as the highest performing industrial carbon fiber on the market and will be used by spar and rigging manufacturer Future Fibres to manufacture their AEROrazr solid carbon rigging for all the teams in the 36th America’s Cup.

Hexcel’s HiMax™ DPA (Dot Pattern Adhesive) reinforcements are non-crimp fabrics supplied pre-tacked, allowing multiple fabrics to be laid-up more easily in preparation for resin infusion. Providing an optimal, consistent level of adhesion, they allow a faster and more consistent resin flow, as well as eliminating the use of spray adhesive for a healthier working environment and lower risk of contamination. Simply unrolled and applied to the mold or core layer before the introduction of resin, HiMax™ DPA fabrics are widely used in boat building, where lay-up times can be reduced by up to 50%.

Wind Energy Innovations

Hexcel has developed a range of HexPly® surface finishing prepregs and semi-pregs for wind turbine blades and marine applications. Providing a tough, durable and ready-to-paint surface without using in-mold coats, these products shorten the manufacturing cycle and reduce material costs. HexPly® XF2(P) prepreg is optimized for wind blades and has a ready-to-paint surface, straight from the mold, saving at least 2 hours of takt time.

Polyspeed® pultruded carbon laminates were developed for load-carrying elements in a blade structure and are manufactured with a polyurethane matrix that provides outstanding mechanical performance in terms of stiffness and durability. The blade manufacturing process is optimized, with increased throughput. The pultruded laminates are supplied in coils as continuous cross section profiles.
HiMax™ non-crimp fabrics using E-glass, high modulus glass and carbon fibers are also available in a wide range of unidirectional, biaxial and triaxial constructions. HiMax™ fabrics have applications throughout the turbine, from the stitched carbon fiber UDs used in the main structural elements, to glass fabrics and hybrids for blade shells and nacelles.

Frau Dr.-Ing. Monireh Fazeli¬ Zoghalchali vom Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik (ITM) der TU Dresden wird am 23. Oktober 2018 für ihre Dissertation "Technologieentwicklung für gewebte Knotenstrukturen mit komplexer Geometrie in Integralbauweise für Faserverbundanwendungen“ mit dem Innovationspreis des Industrieclubs Sachsen 2017 ausgezeichnet. Der Preis ist mit 5.000 Euro dotiert und wird jährlich an einen Absolventen der TU Dresden verliehen.

Die Entscheidung zur Vergabe des Innovationspreises des Industrieclubs Sachsen 2017 erfolgte im Juni 2018 durch ein Preisgericht. Am 23. Oktober findet nun die feierliche Verleihung durch den Industrieclub Sachsen in Dresden statt. Frau Dr. Fazeli absolviert derzeit bis Ende März 2019 im Rahmen des DAAD-Förderprogramms P.R.I.M.E. (Postdoctoral Researchers International Mobility Experience) einen internationalen Forschungsaufenthalt am Centre for Advanced Composite Materials (CACM), University of Auckland in Neuseeland. Deshalb wird Herr Professor Chokri Cherif, Institutsdirektor des ITM und Doktorvater von Frau Dr. Fazeli, den Preis stellvertretend entgegennehmen.

Im Rahmen ihrer Dissertation, die Frau Dr. Fazeli im Dezember 2016 mit der Bestnote „summa cum laude“ abschloss, wurde eine CAE-gestützte Prozesskette zur effizienten automatisierten Fertigung komplexer gewebter Knotenelementhalbzeuge aus Carbonfasern für Rahmentragwerke in Fahrzeugen, Flugzeugen, Maschinen und Anlagen sowie der Architektur realisiert. Für diese Rahmentragwerke in Leichtbauweise steht derzeit bereits ein umfangreiches Sortiment aus faserverstärkten Profilen zur Verfügung. Die erforderlichen Knotenelemente zur Verbindung der Profile sind entweder nach wie vor aus Metall oder müssen extrem aufwändig und somit kostenintensiv gefertigt werden.

Mit der neuen automatisierten Technologie ist es möglich, hochkomplexe, in mehreren Raumrichtungen verzweigte Knotenelemente webtechnisch in einem Stück zu fertigen. Damit entfallen die Prozesse des Zuschnittes und sehr aufwändigen Fügens von Teilflächen. Die Bauteilperformance wird deutlich gesteigert. Am ITM wird in enger Zusammenarbeit mit der Firma MAGEBA International GmbH und durch die finanzielle Förderung von Forschungsprojekten über die AiF im Rahmen des Programms zur Förderung der Industriellen Gemeinschaftsforschung (IGF) vom Bundesministerium für Wirtschaft und Energie (BMWi) die gesamte Prozesskette vom CAD-Entwurf, über die strukturelle Entwicklung, die Erstellung der Maschinensteuerprogramme, die textiltechnische Umsetzung und die Bauteilkonsolidierung erfolgreich erarbeitet.
