STFI: Lightweight construction innovations at JEC World in Paris

At this year's JEC World, STFI will be presenting highlights from carbon fibre recycling as well as a new approach to hemp-based bast fibres, which have promising properties as reinforcement in lightweight construction.

Green Snowboard
At JEC World in Paris from 5 to 7 March 2024, STFI will be showcasing a snowboard from silbaerg GmbH with a patented anisotropic coupling effect made from hemp and recycled carbon fibres with bio-based epoxy resin. In addition to silbaerg and STFI, the partners Circular Saxony - the innovation cluster for the circular economy, FUSE Composite and bto-epoxy GmbH were also involved in the development of the board. The green snowboard was honoured with the JEC Innovation Award 2024 in the “Sport, Leisure and Recreation” category.

VliesComp
The aim of the industrial partners Tenowo GmbH (Hof), Siemens AG (Erlangen), Invent GmbH (Braunschweig) and STFI united in the VliesComp project is to bring recycled materials back onto the market in various lightweight construction solutions. The application fields "Innovative e-machine concepts for the energy transition" and "Innovative e-machine concepts for e-mobility" were considered as examples. On display at JEC World in Paris will be a lightweight end shield for electric motors made from hybrid nonwovens - a mixture of thermoplastic fibre components and recycled reinforcing fibres - as well as nonwovens with 100% recycled reinforcing fibres. The end shield was ultimately manufactured with a 100% recycled fibre content. The tests showed that, compared to the variant made from primary carbon fibres using the RTM process, a 14% reduction in CO2 equivalent is possible with the same performance. The calculation for the use of the prepreg process using a bio-resin system shows a potential for reducing the CO2 equivalent by almost 70 %.

Bast fibre reinforcement
To increase stability in the plant stem, bast fibres form in the bark area, which support the stem but, in contrast to the rigid wood, are very flexible and allow slender, tall plants to move in the wind without breaking.A new process extracts the bast bark from hemp by peeling.The resulting characteristic values, such as tensile modulus of elasticity, breaking strength and elongation, are very promising in comparison with the continuous rovings made of flax available on the market.The material could be used as reinforcement in lightweight construction.At JEC World, STFI will be exhibiting reinforcing bars that have been processed into a knitted fabric using a pultrusion process based on bio-based reinforcing fibres made from hemp bast for mineral matrices.

TMAS: Digitalisation demands streamlined solutions

Fully integrated production lines from single source suppliers have increasingly become the norm in the textile industry and make complete sense in meeting today’s complex supply chain needs, according to TMAS – the Swedish Textile Machinery Association.

“Over the past few decades, textile mills have transitioned from consisting of collections of individual machines serviced and maintained largely by in-house mechanics as well as separate supplier companies for each part of the production line,” says TMAS Secretary General Therese Premler-Andersson. “Those in-house engineering service teams have diminished over the years, while the introduction of electronic drive systems in the 1980s and 90s also put an increased emphasis on the need for third party electrical engineers, operating separately to the machine builders.

“Subsequently, mechanical machines and electronic drive systems became much more integrated, and more recently, with the advent of digitalisation, entire production lines are becoming centrally controlled with remote, instantaneous connections to their suppliers for service and maintenance.

“Subsequently, mechanical machines and electronic drive systems became much more integrated, and more recently, with the advent of digitalisation, entire production lines are becoming centrally controlled with remote, instantaneous connections to their suppliers for service and maintenance.

“In this context, the integration of machinery and automation specialists as single-source suppliers makes perfect sense, while partnerships between machine builders and their customers have never been more important.”

The recent acquisition of Nowo textile machinery from its previous owner, Brandstones Ab Oy, by TMAS member ACG Kinna, she adds, is a good example of this general trend.

Nowo, headquartered in Turku, Finland, designs, manufactures and exports high-end textile production machinery mainly for the fibre processing industry. At the end of the 1980s it introduced the highly successful Nowo Vac pillow filling system, which has been its best-selling system, alongside the Noworoll ball fibre machine, introduced in the 1990s.

Nowo’s machine range covers the entire production process from bale opening to weighing and filling, and complete production lines are tailored to the specific needs of customers. The company can also deliver individual machines such as bale openers, cards, cross-lappers, pickers, mixing devices, material silos, sucking devices, anti-static units etc. Seven patents cover the company’s technologies.

Founded in 1977, ACG Kinna Automatic, based in Skene in Sweden, specialises in customised and cost-efficient solutions for the production of pillows and quilts. All of its design, manufacturing and final line testing is carried out in Sweden and the reliability and longevity of its machines has earned it the trust of the world’s largest furniture and home decoration retailers and Europe’s largest manufacturer of pillows and duvets, among many customers.
