From the Sector

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.

The Lenzing Group has updated its climate targets to align with the goals of the Paris Agreement to limit the human-induced global temperature increase to 1.5 degrees Celsius. The Science Based Targets Initiative (SBTi) has reviewed and confirmed this target improvement.

By 2030, Lenzing aims to reduce its direct emissions from the production of its fiber and pulp plants (scope 1) and its emissions from purchased energy (scope 2) by 42 percent and its indirect emissions along the value chain (scope 3) by 25 percent on the way to net zero, from 2021 baseline. This corresponds to an absolute reduction of 1,100,000 tons (instead of the previously targeted 700,000 tons).

The following targets were recognized and confirmed by the SBTi:

1. Overall net-zero target: Lenzing AG commits to reach net-zero greenhouse gas emissions along the entire value chain by 2050.
2. Near-term targets: Lenzing AG commits to reduce absolute scope 1 and scope 2 greenhouse gas emissions by 42 percent by 2030 from a base year 2021. Lenzing AG also commits to reduce absolute scope 3 greenhouse gas emissions from purchased goods and services, fuels and energy-related activities as well as upstream transport and distribution by 25 percent within the same timeframe.
3. Long-term targets: Lenzing AG commits to reduce absolute scope 1 and scope 2 greenhouse gas emissions by 90 percent by 2050 from a base year 2021. Lenzing AG also commits to reduce absolute scope 3 greenhouse gas emissions by 90 percent within in the same timeframe.

These updated targets replace the old SBTi approved Lenzing Group’s climate target in 2019.

The adoption of composite parts based on flax fibres by the Marine Industry continues to grow, with major OEMs as well as smaller shipyards now aiming to take advantage of the reduced carbon impact and impressive mechanical properties they can provide.

“Over the last ten or fifteen years, several innovative flax fibre boats have been built and the fibre has started to gain significant traction,” says Julie Pariset, Innovation & CSR Director at the Alliance for European Flax-Linen and Hemp. “In addition to the environmental benefits, manufacturers are realising significant technical and processing gains with flax fibre composites.”

“Flax is a very low-density fibre, with a high specific stiffness,” she explains. “It can be used to manufacture composite laminates with mechanical properties not dissimilar to typical E-glass composites and the coefficient of thermal expansion of a flax fibre epoxy part is also quite close to that of a carbon fibre part.” This allows the materials to work well in combined assemblies with carbon fibre composites and the flax parts are also highly impact resistant.

Flax fibres also provide acoustic and vibration damping in composite applications, as well as providing a warm and aesthetically pleasing appearance below decks.

ecoRacer30
As a member of the Alliance for European Flax-Linen and Hemp, Bcomp, headquartered in Fribourg, Switzerland, has this year been working with Northern Light Composites (nlcomp), based in Monfalcone, northern Italy, on the creation of what is billed as the first fully recyclable nine-metre-long sailing boat – the ecoRacer30.

The boat is based on nlcomp’s proprietary rComposite technology – a combination of thermoplastic resins and BComp’s ampliTex high-performance natural fibre reinforcement fabrics and patented powerRibs technology.

It was built in a collaborative effort with the help of Barcelona-based Magnani Yachts, which took care of the composite manufacturing, and Sangiorgio Marine, which provided technical assistance as the boat was being assembled at its shipyard in Genova, Italy.

Magnani Yachts has subsequently become the first shipyard to hold an rComposite license and others are now being encouraged to adopt the technology.

The second ecoracer30 is currently under construction and has already been sold and nlcomp is planning to build a fleet of eight of these boats in time to enter a series of regattas in the summer of 2025.

Flax 27 Daysailer
Greenboats, based in Bremen, Germany, is another specialist in building boats from natural fibre composites and has this year launched the Flax 27 daysailer.

The lower hull of this vessel is also made from Bcomp’s ampliTex technical fabrics in combination with a sandwich core of recycled PET bottles. Using a vacuum infusion process, the fibres were integrated with a plant-based epoxy resin in order to further reduce the CO₂ footprint of the vessel.

The light structure and modern shapes of the lower hull of the boat result in very fast, sharp and agile handling on the water.

Greenboats has also recently announced significant new backing from alliance member Groupe Depestele, which manages 13,000 hectares of flax land in Normandy, France.

Blue Nomad
A project in Switzerland has meanwhile proposed the use of flax fibre composites in solar-powered habitats designed for comfortable living on the oceans – as the world grapples with the frightening implications of climate change and rising sea levels.

As envisaged by students from Institut auf dem Rosenberg in St Gallen, Switzerland working with Denmark-based SAGA Space Architects, Blue Nomad structures would form modular blocks to establish large communities and oceanic farms.
 

Freudenberg Performance Materials (Freudenberg) will present surfacing veils and core materials for lightweight fiber reinforced plastic (FRP) parts at JEC in Paris, France. Freudenberg will also be showcasing Enka® Solutions flow media and spacers for efficient vacuum infusion, resin transfer and foam injection molding processes for applications in the composites industry, etc. at the international composites show.
 
Freudenberg’s solutions for the FRP industry include a variety of glass, PAN and PET nonwovens, as well as core materials for the production of lightweight fiber reinforced plastic parts. These products are designed for anti-corrosion coatings in piping and tank construction, smooth UV resistant surfaces for facade panels, and other applications for a diverse range of end products. Products made from fiber reinforced plastics must be equipped with surfacing veils to provide abrasion resistance, corrosion resistance, smooth surfaces and mechanical strength. Freudenberg offers high-tech nonwovens that can meet these challenges.
 
Enka® Solutions products are characterized by their typical 3D entangled polymeric filament structures. Thanks to this structure, they are exceptionally suitable as flow media and spacers when producing composite materials.

Electronically conductive fibres are already in use in smart textiles, but in a recently published research article, ionically conductive fibres have proven to be of increasing interest. The so-called ionofibres achieve higher flexibility and durability and match the type of conduction our body uses. In the future, they may be used for such items as textile batteries, textile displays, and textile muscles.

The research project is being carried out by doctoral student Claude Huniade at the University of Borås and is a track within a larger project, Weafing, the goal of which is to develop novel, unprecedented garments for haptic stimulation comprising flexible and wearable textile actuators and sensors.

In Claude Huniade’s project, the goal is to produce conductive yarns without conductive metals.
"My research is about producing electrically conductive textile fibres, and ultimately yarns, by coating non-metals sustainably on commercial yarns. The biggest challenge is in the balance between keeping the textile properties and adding the conductive feature," said Claude Huniade.

Currenty, the uniqueness of his research leans towards the strategies employed when coating. These strategies expand to the processes and the materials used.

Uses ionic liquid
One of the tracks he investigates is about a new kind of material as textile coating, ionic liquids in combination with commercial textile fibres. Just like salt water, they conduct electricity but without water. Ionic liquid is a more stable electrolyte than salt water as nothing evaporates.

"The processable aspect is an important requirement since textile manufacturing can be harsh on textile fibres, especially when upscaling their use. The fibres can also be manufactured into woven or knitted without damaging them mechanically while retaining their conductivity. Surprisingly, they were even smoother to process into fabrics than the commercial yarns they are made from," explained Claude Huniade.

Ionofibres could be used as sensors since ionic liquids are sensitive to their environment. For example, humidity change can be sensed by the ionofibers, but also any stretch or pressure they are subjected to.

"Ionofibres could truly shine when they are combined with other materials or devices that require electrolytes. Ionofibres enable certain phenomena currently limited to happen in liquids to be feasible in air in a lightweight fashion. The applications are multiple and unique, for example for textile batteries, textile displays or textile muscles," said Claude Huniade.

Needs further research
Yet more research is needed to combine the ionofibres with other functional fibres and to produce the unique textile devices.

How do they stand out compared to common electronically conductive fibres?
"In comparison to electronically conductive fibres, ionofibers are different in how they conduct electricity. They are less conductive, but they bring other properties that electronically conductive fibers often lack. Ionofibres achieve higher flexibility and durability and match the type of conduction that our body uses. They actually match better than electronically conductive fibres with how electricity is present in nature," he concluded.

Indorama Ventures Public Company Limited (IVL), a global sustainable chemical company, announced its commitment to science-based targets by the Science Based Targets initiative (SBTi) to help drive its ambitious sustainability programs. The company will also participate in the SBTi Expert Advisory Group for the chemicals industry.

SBTi is a collaboration between CDP, the United Nations Global Compact, the World Resources Institute, and the World Wide Fund for Nature to help businesses set emissions reduction targets based on the most recent climate science. IVL has committed to science-based targets under its purpose of “Reimagining chemistry together to create a better world” which aims to reduce global warming in line with the 1.5°C Paris Climate Agreement.

Under its Vision 2030 ambition, Indorama Ventures aims to build on its global industry leadership in sustainability, including by reducing GHG intensity by 30% and increasing renewable electricity consumption to 25%. Green projects are helping the company to achieve its operational efficiency targets, increase its use of renewable energy (especially renewable electricity – both onsite generation and offsite procurement through power purchase agreements), implement new decarbonization technologies including carbon capture, introduce bio-feedstock to its petrochemical value chain, and expand its PET recycling capability.

To meet its targets, IVL recognizes the importance of collaboration between the public and private sectors to decarbonize its operations through a variety of strategies. The established targets help its customers and suppliers to achieve their own sustainability goals, particularly their science-based targets.

Yash Lohia, Chairman of ESG Council at Indorama Ventures, said, "We are pleased to make our sustainability commitment more practical and measurable through science-based targets. We are dedicated to finding new technologies that can transform our operations and products towards net-zero. The efforts are not only for our sustainable business but also to support our customers and suppliers to achieve their own sustainability goals."

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.

• Natural fibers combined with bio-derived epoxy resins provide sustainable options for Industrial markets

Hexcel has developed a new product range that combines Hexcel resin systems made with bio-derived resin content with natural fiber reinforcements to create material solutions for Automotive, Winter Sports, Marine and Wind Energy applications.

HexPly Nature Range includes proven resins such as HexPly M49, M78.1-LT and M79 but with bio-derived epoxy resin content. The excellent resin characteristics remain unchanged in the new Nature Range products, maintaining high mechanical performance and consistent processing properties.
In addition, the HexPly Nature Range provides prepreg options with natural fiber reinforcements that can be seamlessly integrated into existing production processes.

Hexcel worked with TÜV Austria to provide independent, high-quality measurement and assessment of the bio-content of HexPly Nature Range products. TÜV Austria’s OK biobased certification uses a standardized measurement of the biobased carbon content enabling transparency and easy like-for-like comparison between products.

At JEC World in Paris on May 3-5, Hexcel presented an alpine ski produced by the Tecnica Group Ski Excellence Center which produces skis for Blizzard and for Nordica using HexPly Nature Range M78.1-LT UD flax fiber prepreg. In addition to providing a bio-based material solution, the natural fiber-reinforced prepreg also offers the potential to improve impact performance and vibration damping in the ski.

Claude Despierres, VP of Sales and Marketing – Industrial at Hexcel, said, “Our new HexPly Nature Range forms an important part of providing customers with biobased, TÜV-certified material options based on our established prepreg resin systems. Marine, winter sports, wind energy and automotive manufacturers can now have the choice to switch from petroleum-based material solutions to Hexcel HexPly Nature Range with no compromise in performance or process efficiency.”

• The plan for the reference plant is to be operational in 2025 in France (Longlaville) with a processing capacity of 50.000 tons of PET waste per year and creating 150 direct and indirect new jobs.
• Indorama Ventures, the world’s largest producer of recycled PET for beverage bottles, plans to co-invest in this project3 and will consider expanding Carbios’ unique biological recycling process at other PET sites4 for future developments.
• This strategic project is strongly supported by the French Government and the Grand-Est Region, with significant non-dilutive financing.

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers and Indorama Ventures (Bloomberg ticker: IVL.TB), one of the world-leading PET manufacturer, jointly announced a collaboration to build a manufacturing plant operating Carbios’ PET bio-recycling technology at Indorama Ventures’ PET production site in France (Longlaville, Meurthe-et-Moselle).

After having successfully started-up its demonstration plant in Clermont-Ferrand, Carbios is moving one step further towards the industrialization and commercialization by partnering with Indorama Ventures. The goal is to build and operate in France the world’s first industrial-scale enzymatic PET bio-recycling plant, with a processing capacity estimated at ca. 50.000 tons of post-consumer PET waste per year, equivalent to 2 billion PET bottles or 2.5 billion PET trays.

The capital investment required for the project is expected to be around €150 million for Carbios core technology, including in particular an additional purification step, which has been integrated into the process. In addition, an estimated €50 million investment will be allocated for the infrastructure preparation of the site. The project is expected to create approximatively 150 direct and indirect full-time jobs. In the coming months, Carbios expects to finalize a strong non-dilutive financial support from French Government and from the Grand-Est Region5, based on the offer received last week by Carbios, from the Minister of Industry, Agnès Pannier-Runacher and the President of Grand-Est Region, Jean Rottner.

This financial support will be conditional on the notification to the European Commission and on contractualization by French authorities. Carbios announced in its half-year results on the 30th September 2021 a cash position of €112 million. Since then, Carbios has also secured a €30 million loan from EIB.

On March 10th, JEC Group and Composites Expert have signed a partnership agreement to promote E-learning Composites Academy, the first 4.0 training platform dedicated to manufacturing processes of composite materials.

This partnership will start with two first steps: an introduction webinar session on March 15th at 4pm CET, and two sessions of training during JEC World 2022, on Tuesday, May 3rd and Wednesday, May 4th, in Paris where Composites Expert will present the E-learning Composites Academy, a new pedagogical approach aimed at appropriating knowledge of polymer transformation specially developed by Composites Expert.
