From the Sector

Fibre and fabric production technologies – especially in the area of composite reinforcements – have played an as-yet largely unheralded role in the development of the UK’s Formula One industry, but the British Textile Machinery Association (BTMA) aims to change that.

Motorsport Valley
“If there’s one thing the UK does well, it’s Formula One, with seven of the ten F1 teams located within just an hour of each other in the midlands region known as Motorsport Valley,” explains BTMA CEO Jason Kent. “They are all linked to a national network of around 4,500 companies involved in a motorsport and high-performance engineering industry worth around £9 billion annually and employing 40,000 people. This network draws on the services of a significant number of our member companies.”

“With the exception of the engine, virtually every part of a Formula One racing car now starts from a textile, including the bodywork, the tyres and many of the latest fuel systems,” says Richard Kirkbright, project manager at Leeds-based Roaches International. “This has influenced developments in the broader automotive sector, in addition to the aerospace industry.”

Show cars and memorabilia
While best known as the developer of textile testing systems, Roaches has over the years also supplied advanced autoclaves to the UK’s composites industry, including a recent delivery to Northampton-based Memento Exclusives, a specialist in the production of show cars working directly with F1 and its leading teams.

Each major F1 team sponsor is supplied with one or two show cars for use at exhibitions and a wide range of other promotional activities arranged around the racing event calendar. These cars have no engine and their bodies may be made of fewer carbon fibre plies, but they are otherwise identical to the latest cars being raced by the F1 teams.

Memento Exclusives has its own in-house carbon fibre parts manufacturing facility and the integration of the Roaches autoclave has significantly expanded its capabilities in show car production.

Master bakers
“Composite materials undergo a metamorphosis in the autoclave which subjects them to both mechanical and chemical processes,” explains Richard Kirkbright. “Trapped air and volatiles are expelled and plies are consolidated under precise pressure. Heat cycles are then introduced, curing the resin systems and yielding flawlessly crafted components. Autoclave specialists are a little like master bakers, knowing exactly how to treat their ingredients at every stage of the process, to achieve the desired final product.”

“The Roaches autoclave now enables us to cure large components with full control and achieve a swift turnover of parts while ensuring the highest quality finish,” adds Terry Wasyliw, Head of Build for Memento Exclusives.

McLaren’s influence
Woking, UK-headquartered McLaren was the very first F1 team to introduce a car chassis manufactured entirely from carbon fibre composites back in 1981, setting the ball rolling for the creation of a completely new and global supply chain.

McLaren has this year unveiled a world-first in supercar engineering – aerospace-derived Automated Rapid Tape (ART) carbon fibre, developed at the dedicated McLaren Composites Technology Centre (MCTC) facility in Sheffield. This is being employed to create the active front wings of the W1 hypercar which has a starting price of $2.1 million.

A rear floor component was also developed for McLaren as part of the recently-completed £39.6 million ASCEND programme involving a range of UK partners, including BTMA member Cygnet Texkimp.

Handling, converting and decarbonisation
A wide range of handling and converting machines are supplied to the composites industry by Cygnet Texkimp, including bespoke creels, prepreg, coating, slitting and filament winding machines.

Its technologies are employed in the construction of composite components for aerospace and automotive, as well as in the production of tyre cord and more recently in the advanced construction of hydrogen storage vessels which are largely viewed as the future of F1 propulsion, along with advanced batteries for electric vehicles.

Cygnet Texkimp has been involved in the F1 supply chain for over 20 years and most carbon fibre used in the industry has been processed on one of its VHD creels. The company is also the largest independent manufacturer of prepreg machines in the world and is currently leading the design and build of the UK’s first carbon fibre research lines for a project led by NCC (National Composites Centre) to accelerate the development of more sustainable carbon fibres.

In addition, Cygnet is licensed to design and build the DEECOM® composite recycling system developed by new BTMA member Longworth Sustainable Recycling Technologies, the first of which was recently commissioned by the Henry Royce Institute in Manchester. DEECOM® is a zero emission, low carbon pressolysis solution using pressure and steam to reclaim pristine condition fibres and resin polymers frocm production waste and end of life composites.

“Decarbonisation is a major priority for manufacturers globally,” says Cygnet CEO Luke Vardy. “At Cygnet Texkimp, we’re developing the capability to process technical fibres in ways that enable lightweighting, hydrogen power and electrification, reduce waste and revolutionise the end-of-life management of composite materials and parts. In collaboration with our industry partners, we’re bringing to market some of the most innovative new fibre processing technologies ever developed to deliver real-world benefits that support the sustainability agenda.”

Prepregging
Another new BTMA member, Emerson & Renwick (E+R), a specialist in print, forming, vacuum and coating technologies, also supplies technology for the production of carbon fibre prepregs, which are integrated rolls of fabrics and resins.

Its most recent 1.7-metre-wide line supplied to a customer in Italy operates at speeds of 40+ metres per minute for web coatings or prepreg fibre and resin consolidation, or a combination of both processes. It is distinguished by an ultra precise three-roll reverse roll coater for the processing of high viscosity thermo-activated resins and enables the automatic changeover of sensitive woven fabric materials at zero tension, with three high precision calendaring nips with hot/cool plates. Multiple unwind and rewind systems for intermediate lamination steps include side loading and reliable lap splicing and zero speed splicing with a web accumulator for the main product rewind.
 
 E+R has also been part of a consortium working on the development of lithium-sulphur (Li-S) batteries within the £540 million UK Faraday Battery Challenge. Once commercially viable, Li-S batteries promise to provide relatively high energy density at low cost for sustainable electric vehicles of the future – inevitably starting with F1.

Strong links
“In addition to our powerful base of textile testing and control companies, many other BTMA members are working on further F1 and advanced composite projects,” says Jason Kent in conclusion. “We are also forging strong links with the UK’s key research hubs such as Sheffield University’s Advanced Manufacturing Research Centre, the Northwest Composites Centre in Manchester, the National Centre for Motorsport Engineering in Bolton and the National Composites Centre in Bristol.

“The BTMA recently became an associate member of Composites UK too, because this sector is the crucible of innovation for tomorrow’s textiles.”

On November 20th/21st, 2024, the second conference on flame retardancy for composite applications took place in Berlin, organised by the AVK - Industrievereinigung Verstärkte Kunststoffe e.V. in cooperation with the FGK - Forschungsgesellschaft Kunststoffe e.V.

60 participants attended the international event, which this time focused on the requirements in the construction/infrastructure sector in addition to the transport sector.

In 14 presentations, 18 speakers provided information on new developments, requirements and innovations from the fields of standardisation, material development, construction/infrastructure, public transport, automotive and research & science.

Prof. Schartel from the Bundesanstalt für Materialforschung und –prüfung began with an introduction to the principle and concept of flame-retardant composites. In the following thematic blocks, the companies CTS Composite Technologie Systeme GmbH and Nabaltec AG provided information on new possibilities and developments at the material level of non-combustible fibre-reinforced plastics (FRP).

The implementation of fire protection requirements in the operation of rail vehicles or for load-bearing FRP components played a major role in the area of construction/infrastructure, as did the sustainability of these building materials, which Frank Lüders from DB Systemtechnik GmbH and Kabelan Thavayogarajah from Fraunhofer LBF reported on in their presentations.

The well-known topic of e-mobility took its place in the automotive sector, where Dr. Christian Battenberg from Clariant Plastics &Coatings (Deutschland) GmbH spoke about flame retardants for applications in this field.

The successful event was rounded off by the Research and Science block with two presentations by Fraunhofer LBF and Deutsches Textilforschungszentrum Nord-
West gGmbH & Centre for Nanointegration Duisburg-Essen.

Over the course of one and a half days, the conference provided an important platform for experts from industry and science to discuss the latest developments and challenges in the field of flame retardancy for composites. The high level of participation highlighted the relevance of the topic and underpinned the decision to organise a third round of the conference in 2026.

Vor dem aktuellen Hintergrund frei gewordener Mittel aus anderen Töpfen des Bundeshaushalts appelliert die deutsche Composites-Industrie an die Politik, sich wieder für das TTP LB und dessen Finanzierung im geplanten Umfang einzusetzen. Insbesondere für mittelständische Unternehmen und Startups müsse das Programm für deren Wettbewerbsfähigkeit und damit zur Sicherung und Schaffung zukunftssicherer Arbeitsplätze wiederbelebt werden, um letztlich auch zum Erhalt des Wohlstands in Deutschland beizutragen.

Mit dem Technologietransferprogramm Leichtbau (TTP LB) hatte das Bundesministerium für Wirtschaft und Klimaschutz (BMWK) eine wichtige Unterstützung für eine erfolgreiche Transformation der in diesem Bereich tätigen Unternehmen geschaffen. Es war Innovations- und Transfertreiber für Energie- und Ressourceneffizienz und mitentscheidend für die Erreichung der ambitionierten europäischen und deutschen Klimaschutzziele. Mit großer Sorge hatte die Faserverbund- bzw. Composites-Industrie festgestellt, dass das Programm Anfang dieses Jahres Sparzwängen des Bundeshaushalts zum Opfer fiel. Dabei wurde der Leichtbau als Schlüsseltechnologie für Deutschland im Koalitionsvertrag der Bundesregierung verankert und durch deren dann folgende Leichtbau-Strategie manifestiert.

Ohne Leichtbau werde es keinen ausreichenden Klimaschutz geben: 70 % der Treibhausgasemissionen stammen aus der Nutzung von fossilen Rohstoffen wie Erdgas, Erdöl und Kohle, um hauptsächlich Energie zu gewinnen. Daher sei die Transformation in Richtung Erneuerbare Energiegewinnung z. B. durch Windenergie und grünen Wasserstoff von entscheidender Bedeutung für den Erfolg des European Green Deal. Beide Technologien seien ohne Leichtbau nicht umsetzbar: Windenergieanlagen nutzen den multi-materialen Leichtbau mit Glasfaserverstärkten Kunststoffen, Kohlenstofffaserverstärkten Kunststoffen (CFK), Holz und Metallen und die Lagerung des Wasserstoffs erfolgt in CFK-Behältern.

Darüber hinaus sei der Leichtbau eine Game-Changer-Technologie für Deutschland: Durch diese innovative und wettbewerbsfähige Schlüsseltechnologie lassen sich sowohl Materialien in der Produktion sparen als auch Energie bei der späteren Nutzung der Produkte. Branchen wie unter anderem das Bauwesen, der Maschinenbau und der gesamte Transportsektor können davon stark profitieren.

Insbesondere vor dem Hintergrund der aktuellen Probleme der deutschen Automobilindustrie erscheinen auch mit Fördermitteln unterstützte Innovationen zu Leichtbaukonzepten für PKW und LKW unerlässlich für die Wettbewerbsfähigkeit dieses wichtigen volkswirtschaftlichen Sektors in Deutschland.

Auf europäischer Ebene hat die Composites-Industrie über das vom BMWK ins Leben gerufene European Lightweighting Network (ELN) Werbung für eine europäische Leichtbaustrategie gemacht und bereits viele europäische Partner gefunden. Um weiterhin als Impulsgeber und Gestalter vorangehen zu können und glaubwürdig den Leichtbau als Schlüsseltechnologie für Europa zu promoten, sei eine tatkräftige politische Unterstützung im Rahmen des TTP LB in Deutschland essenziell.

With the MAX GLASS ECO, the KARL MAYER Technical Textiles Business Unit offers a production machine for the economical manufacture of standard reinforcement textiles made from glass fibers, in particular non-crimp fabrics for the wind power industry. The newcomer can be adapted to the requirements of different application areas thanks to various optional functions and combines short amortization times. At a maximum speed of 1,800 min-1, it produces up to 410 m/h at a working width of 101". This performance is very well received on the composite market. Since the launch of the MAX GLASS ECO at JEC World in March this year, several purchase agreements have already been signed.

Some machines are going to India, and a larger number has been ordered by Chinese customers. Even the demonstration models in the KARL MAYER GROUP customer centers in Changzhou and Chemnitz have already been sold. However, the MAX GLASS ECO at KARL MAYER Technische Textilien in Saxony can still be used for processing trials and performance tests until September.

There is also great interest in Eastern Europe. At Techtextil 2024 in Frankfurt, for example, the new composite machine was a topic of numerous meetings with Ralf Schramm, Sales Manager at KARL MAYER Technische Textilien for this region. "I held many orientation discussions about the machine's performance. But there were also customers with specific purchase requests, including the Polish manufacturer of high-quality, professional solutions for the composites industry, Rymatex," says the sales professional.

With four months until the show opens doors, key exhibitors have already confirmed participation for the Cinte Techtextil China 2024. In conjunction with a positive global outlook, key players are eager to congregate again at the Shanghai New International Expo Centre from 19 – 21 September, to showcase innovations and connect with buyers from various sectors.
 
The fair will closely align with Messe Frankfurt’s ‘Texpertise Econogy’ – the umbrella for the group’s sustainability activities at its more than 50 textile trade shows worldwide. New energy elements, such as battery and hydrogen, will appear at the Innovation Showcase Area, on top of other interactive fringe events which centre around sustainability.

With environmental protection as one of the top sourcing categories at the previous edition, products with medical, home, protection, and building applications rounded out the top five. By product group, in-demand sourcing categories included nonwovens; technology and accessories; woven fabrics, laid webs, knitted fabrics, braidings; composites; as well as coated textiles and bondtec. The show saw 15,542 visits from 52 countries and regions last year.

Catering to various key players in 2023, the well-known Groz-Beckert East Asia brought their latest innovative needling tools for the nonwovens sector. Speaking at the show, Mr Kabilen Sornum, Vice President Asia Pacific of Marketing & E-Commerce, commented: “While we are focusing on the China market, we have also seen buyers from the Middle East, Europe, Korea, and North Asia. Cinte Techtextil China is a more international fair – we can see that everyone is here, and the quality and innovation of buyers has improved greatly in the past three to four years. E-mobility and sustainability are two very clear trends.”
 
The fair’s product categories cover 12 application areas, which comprehensively span a full range of potential uses in modern technical textiles and nonwovens. These categories also cover the entire industry, from upstream technology and raw materials providers to finished fabrics, chemicals and other solutions. This scope of product groups and application areas ensures that the fair is an effective business platform for the entire industry.

ACG Kinna Automatic and ACG Nyström – members of TMAS, the Swedish textile machinery association – have delivered the first microfactory for the production of fully finished filter bags to an international filtration industry customer, in cooperation with JUKI Central Europe.

The microfactory’s configuration is based on two separate interconnecting modules – the Smart Filter Line (SFL) and the Filtermaster 2.0. The SFL handles the fabric feeding from rolls and its folding prior to seam construction, which can either be by automatic sewing, welding or with sewing and taping, depending on specifications. Very rapid changeover of the modular seaming methods can be achieved during product changes. The specific size of the now fully-tubular fabric is then precisely cut to size for each individual unit and further folded ready to be fed into the Filtermaster 2.0. The Filtermaster 2.0 then automatically attaches the reinforcement, bottom and snap rings onto the filter tube with a second Juki sewing head on a robotic arm, to form the fully finished filter bag ready for packaging.

Filter bags are employed in a wide range of industrial processes and while they may be largely under the radar as products, they represent a pretty significant percentage of overall technical textiles production.
They are used in foundries, smelters, incinerators, asphalt plants and energy production plants. Other key manufacturing fields – often where dust is generated – include the production of timber, textiles, composites, waste handling and minerals, in addition to chemicals, food production, pharmaceuticals, electronics and agriculture.

As a further example of the scale of the industry and the high volumes of fabrics involved, one supplier has delivered a single order of 30,000 filter bags to be used for flue gas cleaning at a European power plant. The bags can also be anywhere up to twelve metres in length and frequently have to be replaced.

After a long phase of continuous growth, the composites market has seen strong fluctuations since 2018. In 2023, the overall market for composites in Europe fell by 8%.

The current mood on the markets in Germany and Europe is rather negative within the industry. The main drivers are the persistently high energy and raw material prices. Added to this are problems in logistics chains and a cautious consumer climate. A slowdown in global trade and uncertainties in the political arena are fueling the negative sentiment. Despite rising registration figures, the automotive industry, the most important application area for composites, has not yet returned to its pre-2020 volume. The construction industry, the second key application area, is currently in crisis. These factors have already caused the Eu-ropean composites production volume to fall significantly in recent years. There has now been another decline in Europe for 2023.

Overall development of the composites market
The volume of the global composites market totalled 13 million tons in 2023. Compared to 2022, with a volume of 12.3 million tons, growth was around 5%. In comparison, the European composites production volume fell by 8% in 2023. The total European composites market thus comprises a volume of 2,559 kilotons (kt) after 2,781 kt in 2022.

The market is therefore declining and falling back to the level of 2014. Overall, market momentum in Europe was lower than in the global market. Europe's share of the global market is now around 20%.

As in previous years, development within Europe is not uniform. The differences are due to very different regional core markets, the high variability of the materi-als used, a wide range of different manufacturing processes and widely differing areas of application. Accordingly, there are different regional trends, especially with regard to the individual processes, although there were declines in all re-gions and for almost all processes in 2023. At almost 50% of the market volume, the transportation sector accounts for the largest share of total composites pro-duction in terms of volume. The next two largest areas are the electri-cal/electronics sector and applications in construction and infrastructure.

Auch diese Initiative sei durch den Ausfall einer deutschen Unterstützung in Frage gestellt.

Die Unternehmen in Deutschland und insbesondere der Mittelstand stehen in einem internationalen Wettbewerb, den sie nur durch innovative und leistungsfähigere Produkte standhalten können, die im Sinne des Klimaschutzes nachhaltig zu gestalten sind. Wettbewerbsdruck entstünde insbesondere seitens der USA und China, die hohe Subventionen dafür bereitstellen.

Als Branchenvertreter appelliert der Verband an die Politik, sich wieder für das TTP LB und dessen Finanzierung im geplanten Umfang einzusetzen. Auch insbesondere für mittelständische Unternehmen und Startups müsse das Programm für deren Wettbewerbsfähigkeit und damit zur Sicherung und Schaffung zukunftssicherer Arbeitsplätze wiederbelebt werden, um auch zum Erhalt des Wohlstands in Deutschland beizutragen.

• 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 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.
