Recycled carbon fiber: When a Boeing 787 turns into a Lenovo ThinkPad

Toray Industries, Inc. announced the successful development of recycled carbon fiber (rCF) derived from the production process of the Boeing 787 components using Toray’s advanced carbon fiber, TORAYCA™. The rCF, which is based on pyrolysis recycling process, has been integrated into the Lenovo ThinkPad X1 Carbon Gen 12 as reinforcement filler for thermoplastic pellets. Toray and Lenovo will continue to collaborate to expand the usage of rCF in other Lenovo products.

Toray rCF is the outcome of Boeing and Lenovo’s shared commitment to minimize their environmental impact. Boeing’s objective is to reduce solid waste going to landfill and produce recyclable materials, while Lenovo has been exploring materials to reduce the carbon footprint of their products. Toray rCF connects these visions by repurposing Toray’s high-performance carbon fiber from the Boeing aircraft production process into Lenovo’s ultra-light laptop PC.

Toray rCF connects these visions by repurposing Toray’s high-performance carbon fiber from the Boeing aircraft production process into Lenovo’s ultra-light laptop PC.

TORAYCA™ is an established aerospace material known for its high strength, stiffness, and lightweighting properties. These qualities have led to its adoption in other applications such as electrical and electronic equipment housings, sports equipment, and other industrial applications.

A key advantage of carbon fiber is the ability to retain its primary mechanical properties even after the recycling process. Toray is actively advancing recycling technologies and establishing a strategic business model for rCF. Given that the carbon footprint of rCF is lower than that of virgin carbon fiber, Toray is proactively recommending the adoption of rCF to reduce the environmental impact of customers’ products. This commitment aligns with Toray’s dedication to fostering a circular economy, thereby reducing landfill waste.

Faster and cheaper carbon fibre production with CarboScreen

Faster and more cost-effective carbon fibre production - the technology of the start-up CarboScreen comes a good deal closer to this dream. The founders Dr. Musa Akdere, Felix Pohlkemper and Tim Röding from the Institut für Textiltechnik (ITA) of RWTH Aachen University are using sensor technology to monitor carbon fibre production, thereby doubling the production speed from the current 15 to 30 m/min in the medium term and increasing turnover by up to €37.5 million per year and system. This ground-breaking development also impressed the jury at the ITMF at their Annual Conference in Keqiao, China, and was honoured with the ITMF StartUp Award 2023 on 6 November 2023.

Dr. Musa Akdere accepted the award on behalf of the CarboScreen founding team.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Both types of damage cannot be optimally detected by current means or only become apparent after production, to name just two examples. This leads to higher production costs. In an emergency, faulty production can even lead to plant fires. For this reason, and to ensure good production quality, the system is run at 15 m/min below its production capacity for safety reasons. However, 30 m/min or more would be possible. With the sensor-based online monitoring of CarboScreen, the production capacity can be doubled to 30 /min. This would lead to higher production, resulting in lower manufacturing costs and wider use of carbon fibres in mass markets such as automotive, aerospace and wind energy.

Hypetex’s paint-replacement technology retains the visible weave, allowing for a bold design and a choice of colours without technical compromises, perfectly aligning with BAC’s initiatives to maximise performance whilst creating bespoke supercars. Paint generally adds 138 grams per metre squared, whereas Hypetex adds just 17 grams for the same area, offering an 8x weight saving.
This bespoke version of BAC’s single-seater Mono R was subject to BAC’s renowned BAC Bespoke programme, which ensures that no two Monos are the same. The client, a US-based collector, worked with BAC’s design team to design the car to their personal taste.   

Born out of Formula 1 technology, Hypetex offers manufacturers sustainable aesthetic materials with technical and efficiency benefits. This collaboration is an all-British success story, with the Hypetex carbon fibre body built by Formaplex, a leading UK-based manufacturing company who manufacture lightweight engineered solutions for top tier customers in Automotive, Aerospace and Defence markets. BAC’s supply chain is 95% UK-based.  

Hypetex continues to expand its growing portfolio of the use of coloured carbon fibre to add personalisation to the automotive field, with its material recently featured on the 2024 Ford Mustang Dark Horse.

Future cost reduction through ultra-thin PE carbon fibres

  • ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

The company expects to achieve adjusted EBITDA (EBITDA pre = earnings before interest, taxes, depreciation and amortization before one-off effects and non-recurring items) of €170 - €190 million (previously: €130 - €150 million) in 2022.

Based on lower prices for acrylonitrile as main raw material of the Business Unit Carbon Fibers as well as higher than expected customer demand for acrylic and carbon fibers combined with consistently good production capacity utilization and capability, the management of SGL Carbon SE assumes an improved earnings development of this Business Unit.

SGL Carbon assumes that the factors mentioned will continue at least until the end of the year and that the earnings situation of the Business Unit Carbon Fibers will exceed previous expectations. Combined with the continued good business development of the other three Business Units (Graphite Solutions, Process Technology and Composite Solutions), an improvement in the sales and earnings situation at Group level is expected.

In line with the forecast increase for adjusted EBITDA (EBITDA pre) to between €170 and €190 million (previously: €130 - €150 million), the company is forecasting adjusted EBIT (earnings before interest and taxes and before one-off effects and non-recurring items) of between €110 and €130 million (previously: €70 - €90 million). The forecast for return on capital employed (ROCE) of originally 7% - 9% has been raised to 10% to 12% corresponding to the development of earnings. The expectations for free cash flow (significantly below previous year's level of €111.5 million) remain unaffected by the expected improvement in sales and earnings.

The updated forecast for fiscal 2022 has been prepared on the basis of the currently prevailing market environment and assumes no deterioration in the general conditions, in particular due to the war in Ukraine and its consequences for the global economy.
 
The definition of key figures used in this release is aligned to the Annual Report 2021. There were no changes in the scope of consolidation or accounting methods compared with the previous guidance.

  • Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times

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.

  • 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.

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.

  • 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.“
