From the Sector

Technically and economically viable lightweight production based on fiber-reinforced plastics and multi-material systems requires an integrated approach. Due to the almost unlimited combination possibilities of different materials and the very complex interactions between materials, component design, manufacturing processes and the machine and system components, an optimal production process requires a direct link between materials science, process engineering and production technology.

As the official center for “Composite-based Lightweight Production” of the RWTH Aachen Campus, AZL Aachen GmbH uses its strong network to provide these capacities and possibilities on an interdisciplinary basis. Within walking distance, researchers and students are working on the latest technologies for the cost-efficient development and production of lightweight components on one of the largest research landscapes in Europe - the RWTH Aachen Campus: Aachen Center for Integrative Lightweight Production of RWTH Aachen University, Fraunhofer Institute for Production Technology IPT, Fraunhofer Institute for Laser Technology ILT, Institute for Automotive Engineering (ika) of RWTH Aachen University, Institute for Plastic Processing in Industry and Craft at RWTH Aachen University, Institute of Structural Mechanics and Lightweight Design (SLA) of RWTH Aachen University, Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University, Production Engineering of E-Mobility Components (PEM) of RWTH Aachen University, Welding and Joining Institute (isf) of RWTH Aachen University.

Exklusive insights into the latest lightweight technologies

Once a year, the AZL Open Day offers an exclusive and unique insight into the R&D capacities of the institutes in the field of lightweight construction and sustainable mobility. This year, nine AZL partner institutes opened their machine halls and research laboratories on April 9, 2025 to provide interested industrial players with comprehensive insights into their current focus areas along the value chain. Among other things, the institutes presented high-precision laser processes for plastics processing, new joining processes for thermoplastic composites, 5-axis CNC machining with real-time quality management, large-format 3D printing and their own tape lines & tape integration. Design, prototyping and testing of products & solutions such as crash-optimized vehicle structures, thermoplastic pressure vessels, digital twins for structural-mechanical monitoring as well as prototyping and recycling approaches for battery systems were also demonstrated. The range of topics, key activities & infrastructure, seen at the Open Day, enables new technologies to be tested under real production conditions and efficiently brought to market maturity.

“The AZL Open Day is a great opportunity to discover the numerous technology centers, labs, prototyping and testing facilities that are available on the Aachen campus, that makes it unique in its kind. The AZL organization and teams located there are a true catalyst for new projects and development for the Composites industry: they are creating the link between Market analysis & technology scouting, academic research resources and business opportunities with their industrial partners. They are currently working on several topics that are at the forefront of Composites” reports Éric Pierrejean, CEO of the JEC Group. Apart from being there as an interested participant, he also gave the audience an insight into the key topics and trends in the composites industry as seen at this year's JEC World Show.

Efficient use of established infrastructures & know-how

As a one-stop shop for lightweight solutions, AZL offers an interface for successful cooperation between research and industry. In close coordination between scientific developments and specific customer requirements, solutions are developed in a targeted and tailor-made manner: as part of the AZL partnership, consortial projects or individual projects. In addition to the know-how of the institutes, cooperation with the AZL's industrial partner network also enables direct access to the necessary infrastructure of components, materials, tools and machine and system parts, which can be tested, developed or newly constructed in integrated process chains on a large scale.

Thanks to the close networking between science, industry and the AZL team of experts, companies can access an established infrastructure and utilize synergies for their projects.
The date for the next AZL Open Day will be announced in the second half of the year.

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.”

Bcomp, a company in high-performance, natural fibre composites for the mobility-, recreational-, and mass transportation sectors, has been awarded the 2024 Altair Enlighten Award with BMW M GmbH, a renowned performance car subsidiary of BMW Group, for the BMW M Visionary Materials Seat, alongside other BMW M GmbH partners in the project. Manufactured with Bcomp’s ampliTex™ bio-based materials, the seat won in the Sustainable Process category.

The award-winning seat design re-envisions the manufacture and component materials to introduce a lighter, circular product that meets the demands of large-scale vehicle production. The seatback features a fully bio-based, high-performance natural fibre layup with ampliTex™-PP composite. By combining the structural and aesthetically pleasing visual properties of the material in one manufacturing step, production is both more efficient and dematerialised.

The accent has been on Design for Circularity, meaning that in addition to using natural and recycled materials, the BMW M Visionary Materials Seat’s recyclability has been taken into account right from the start of development. Less complex assemblies and monomaterials that can be separated by type enable the recyclability of the seat at the end of its life. Flax fibre composites are CO₂e-neutral from cradle to gate, and can reduce manufacturing-related emissions of high-performance composite parts by up to 85% compared to carbon fibre, depending on the application. Compared to current large-scale automotive plastic parts, Bcomp’s material solutions can reduce component weights by up to 50%, thanks to their low density and high stiffness.

The seat is a development project designed and engineered by long-time collaborators, BMW M GmbH and Bcomp, along with BMW Designworks, Automotive Management Consulting GmbH, Gradel Lightweight Sàrl and Lasso Ingenieurgesellschaft mbH. BMW M GmbH and Bcomp have already delivered innovations in previous development projects for high-end road cars and series application for race cars, such as interior and bodywork components for the BMW M4 GT4, bodywork for the BMW M4 DTM, and cooling shafts for the BMW iFE.20 in Formula E.

The annual Enlighten Awards are sponsored by Altair, a global leader in computational science and intelligence. They celebrate lightweighting innovations that reduce emissions, materials and energy consumption, while advancing material reuse and recyclability. The winning technologies are of significant interest to automotive engineers, manufacturers, policymakers and consumers.

AZL Aachen GmbH announces the launch of a new Joint Partner Project focusing on the further growth potential and technology developments for composite propellers in the field of air mobility and for composite rotors for small to medium-sized wind energy systems.

The nine-month consortial industry project will investigate current and future composite applications for propellers and rotors and their requirements, provide technological insights and develop new product concepts and evaluate them in terms of economic efficiency.

The project aims to address the growing demand for efficient, powerful and compact composite propellers and rotors for the growing markets of air mobility and decentralised power generation. Although the application, manufacturing and material technologies for propellers and rotors made of composite materials have proven to be technically mature, they have so far mainly been used in the high-performance sector for large propeller aircrafts and large wind turbines. Due to the increasing interest in efficient electric propulsion system in the field of air mobility, e.g. air taxis or parcel delivery drones, as well as for decentralised energy generation with the help of small/medium-sized wind energy systems, a rising demand for these components and their production volumes are expected.

AZL will bring together experts along the entire value chain in the project to analyse current and future product concepts. During the project, the participating companies will gain a comprehensive understanding of composite propeller and rotor technology. The project team will carry out a detailed screening of current and future technologies, investigate different materials and processes for the production of propellers and rotors and elaborate design options as well as analyse and evaluate them in terms of technological and cost-effective criteria.

Interested companies can join the project consortium until the Kick-Off on September 18th, 2024.

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.

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

The STOLL Business Unit will be focussing on thermoplastic materials. Several knit to shape parts with a textile outer surface and a hardened inner surface will be on display. The double-face products can be made from different types of yarn and do not need to be back-moulded for use as side door panels or housing shells, for example. In addition, the ready-to-use design saves on waste and yarn material.

The combination of high strength and rigidity with sustainability and a neutral carbon footprint makes flax the ideal raw material for natural fibre-reinforced plastics. vombaur offers composite textiles made of this natural fibre for the automotive, wind power, construction or sports industries and many other sectors.

Flax fibres are rigid and tear-proof. They have natural bactericidal properties, are virtually antistatic, stain resistant and easy to spin. Humans have taken advantage of these properties to manufacture robust, stain-resistant and lint-free textiles. Between the late 19^th and late 20^th centuries, cotton largely replaced natural fibres. Because flax can be grown in Europe and consumes less energy and water than cotton production, the material's importance is currently growing again, for both clothing and composites. Regional textile value added chains in Europe – flax makes them possible.

Ideal mechanical properties
vombaur makes the mechanical properties of flax usable for lightweight design. Because flax fibres are particularly rigid and tear-resistant, they ensure great stability in natural fibre-reinforced plastics (NFRPs). And thanks to their low density of 1.50 g/cm3, the fibres weigh virtually nothing. On top of this, fibre-reinforced plastics are less prone to splintering than glass fibre-reinforced plastics.

Excellent carbon footprint
The cultivation of flax binds CO₂ and the production of natural fibre-reinforced plastics (NFRPs) generates approximately one third less CO₂ emissions compared with conventional fibre-reinforced plastics. Energy consumption is substantially lower. This saves resources. The use of flax fibre tapes by vombaur in lightweight design applications also improves the product's carbon footprint and contributes to a secure, regional supply chain.

Recycling without impacting on quality
Flax offers another sustainability benefit: more recycling cycles than glass- or carbon fibre-reinforced plastics – without impacting on quality. Thermoplastic fibre-matrix prepregs are melted and reused in the recycling process. The natural fibres can be used in other products such as natural fibre-reinforced injection moulded parts.

Sustainable product developments for many industries
"Orthoses for high-performance sports, high-tech skis, wind turbines, components for the automotive industry or aerospace, but also modern window profiles – the application scope for our lightweight design flax tapes is amazingly diverse", as Carl Mrusek, Chief Sales Officer at vombaur explains. "After all, wherever flax tapes are used, three key properties come together: light weight, strength and sustainability".
