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.
 

The textile machinery orders index, as processed by the Economics Department of ACIMIT, the Association of Italian Textile Machinery Manufacturers, dropped fully 20% during the third quarter of 2023, compared to the same period for July to September 2022. In absolute terms, the index stood at 84.2 points (basis: 2015=100).

This result is due to a reduction in new orders recorded by manufacturers both on the domestic market and abroad. The decrease in orders in Italy came in at 45%, whereas the drop was just 13% on foreign markets. The absolutevalue of the index abroad stood at 80.5 points, and 119.4 points in Italy. During the year’s third quarter, new orders reached 3.7 months of assured production.

ACIMIT President Marco Salvadè commented on the data, stating that, “The order index for the period from July to September 2023 confirms a contraction in collected orders that was already evident in previous quarters. What worries us above all is the situation with our domestic market, where the declining trend has persisted for seven consecutive terms. Due to this situation, which does not only concern the textile machinery industry, urgent measures are needed from Italian Government to strengthen the competitiveness of Italian manufacturers.”

As far as foreign markets are concerned, the orders index confirms an overall weakened global demand for textile machinery. Indeed, for the first half of 2023, Italian exports slowed in a variety of essential benchmark markets, such as Turkey, China and the United States.

“The global economic scenario remains negative, as consumers are facing a reduced purchasing power, with investments in the textile sector consequently also slowing down,” concludes Salvadè. “In less than a month, ITMA ASIA + CITME will be held from 19 to 23 November in Shanghai, primed as one of the world’s major trade fairs for the textile machinery industry, with the participation of roughly 60 Italian textile machinery manufacturers. We can expect some significant indications on the industry’s state from this event, which will be staged in one of the strategic markets for textile machinery demand.”
