From the Sector

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.

• 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.

• Project from the Global Organic Textile Standard, European Space Agency and Marple will use AI and satellite imagery to detect organic versus non-organic cotton fields
• Innovative demonstrator project explores the potential of remote monitoring to strengthen integrity and development of organic cotton cultivation
• Project will run across India with first results expected by the end of 2023

In a world first, the Global Organic Textile Standard (GOTS), European Space Agency (ESA) and AI company Marple have today launched a new demonstrator project that aims to show the potential for remote satellite monitoring of organic cotton cultivation systems.

The project, to be carried out under ESA’s Business Applications and Space Solutions (BASS) programme, will train artificial intelligence (AI) to use ESA satellite data to detect cotton fields across India and automatically classify them according to their cultivation standard. By integrating standardised yield metrics, this innovative approach will also enable GOTS to generate realistic estimates of organic cotton yields in specific areas.

Integrated with existing GOTS measures, this project will enable GOTS to further enhance the integrity of organic cotton by developing advanced risk assessment technology for organic certification and preventing fraud from the beginning of the supply chain. “It is an honour and very exciting to be a partner in this ESA Demonstration Project, and it is living up to our claim to be pioneers serving the sustainable textile sector to enable continuous improvement. Technologies like this will be a game changer regarding the integrity and promotion opportunities of organic cotton.” says Claudia Kersten, Managing Director of GOTS.

The project's anticipated impact extends beyond identifying certified organic cotton fields. It is expected to also empower GOTS to recognise cotton fields that have not yet obtained organic certification but possess the potential for a seamless transition to organic cultivation, thanks to their utilisation of traditional and ecologically friendly farming practices. This would enable GOTS to bring a greater number of farmers – particularly those of a smaller size – into the certified organic sector and supply chains, creating new economic opportunities for small-scale farmers and their communities while also helping the textile sector to meet growing consumer demand for organic cotton. Guillaume Prigent, Business Development and Partnerships Officer at the European Space Agency, adds: “This project highlights how space solutions can have a positive impact on the world and is the kind of innovation that ESA supports through its Business Applications and Space Solutions programme.”

The project will run across the distinct cotton growing regions in India, with first results expected by the end of 2023.

India project builds on successful Uzbekistan feasibility pilot
The project is co-financed by GOTS and ESA, in collaboration with Marple GmbH, a German software development firm that developed the CoCuRA (Cotton Cultivation Remote Assessment) software with ESA BASS and successfully piloted it in a feasibility project in 2021 in Uzbekistan.

That venture showed how the trained AI was able to accurately differentiate cotton fields from other crops using only satellite images and sensor data, as well as whether the cotton fields were cultivated organically.

This spurred considerable interest from GOTS, which has committed to the development of cutting-edge technologies that can improve the integrity of the organic textile sector, especially cotton. Dr David Scherf, co-founder of Marple, said: “All our projects strive to leverage advanced technology for a positive impact on the environment and society. We are therefore delighted that our CoCuRA technology, which emerged from a moonshot research project, is being applied in a practical and impactful way. We are excited about the opportunity to work with the exceptional team at GOTS and further strengthen our successful partnership with ESA.”

Fibre Extrusion Technology Ltd (FET) of Leeds, UK has strengthened its technical team with the appointment of Dr Jonny Hunter as Research & Development Manager. Hunter brings a wealth of academic credentials to the department, including a Master’s in Medicinal and Biological Chemistry and a PhD in Sustainable Chemistry. This academic background is complemented by over 10 years’ R&D experience in industry, including FMCG and, in particular, medical devices, which encompasses wound care, the medical device manufacturing process and regulatory environment.

FET designs, develops and manufactures extrusion equipment for a wide range of high value textile material applications, so the above research and industrial sectors have great relevance to the company’s focus on the international stage. A significant market for FET’s meltspinning equipment is medical devices, so in-house expertise in this area is a vital commodity. FET is also at the forefront of innovation to promote and develop sustainable fibres, so technical knowhow in sustainability is also essential. In this, Jonny Hunter has considerable experience and has in the past lead a number of innovation projects in sustainable chemistry and management.

This fresh input of knowledge and experience will benefit FET’s customers in their own drive for sustainable innovation in fibre technology. Mark Smith, the previous R&D Manager, is taking a short sabbatical and will be returning in a more strategic role as FET’s Director of Technology, so his continued presence will further contribute to FET’s breadth of technical expertise.

FET has also expanded in a number of other departments to reflect the rapid growth in sales over recent years. Mike Urey is the new Sales Engineer, bringing a wide industrial experience and strengthening all aspects of business development. Three new mechanical and electronic engineers and a new appointment in the design department all combine to take the company forward and sustain growth.

Viscose speciality fibre manufacturer Kelheim Fibres, nonwoven producer Sandler, and hygiene product manufacturer pelzGROUP have jointly developed a new panty liner that is plastic-free according to the European Single-Use Plastics Directive (SUPD). This innovative solution is a step towards reducing the amount of plastic in hygiene products – and thus also a contribution to tackling the problem of plastic pollution.

According to a UNEP study on marine litter and microplastics, eight million tons of plastic end up in the oceans every year. A significant portion of this pollution comes from single-use plastic products, including conventional period products such as pads or panty liners.

The partnership between the three companies was formed under the Open Innovation principle, which allowed for creative idea exchange and facilitated the development of an innovative product. According to Jessica Zeitler, R&D Specialist at Sandler, “Our collaboration with Kelheim Fibres and pelzGROUP is a great example of how companies can work together to create solutions that benefit both the environment and consumers. We are proud to be part of this project and the opportunities it offers.”

For hygiene product manufacturer pelzGROUP, it is important to combine sustainability and performance to achieve broad acceptance in the market. “Our panty liner meets the strict requirements of the European Single-Use Plastics Directive (SUPD) while also matching the performance of conventional synthetic products. At the same time, our new panty liner has a completely European supply chain. This means short distances and therefore low CO2 emissions, and – especially in times of global disruption – reliability for our customers,” emphasizes Dr. Henning Röttger, Head of Business Development at pelzGROUP.

"Our viscose speciality fibres are an environmentally friendly and high-performance alternative to synthetic materials," says Dominik Mayer, Project Manager Fibre & Application Development at Kelheim Fibres. "They are at the very beginning of the product value chain and yet have an enormous impact on the functionality of the end product. Open innovation allows us to bring all partners in the value chain to the table, to find the best solution together in a very short time and bring it to commercialisation - the collaboration with Sandler and pelzGROUP is an important milestone in our AHP journey."
