STFI presents 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. Visit us at the joint stand of the Saxony Economic Development Corporation and talk to our team of lightweight construction experts.

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 (Braun-schweig) 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 rein-forcement 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.

Meet STFI in Paris

The green snowboard from silbaerg, the bearing shield for the electric motor and the bast fibre reinforce-ment can be seen together with other STFI research highlights from 5 to 7 March 2024 at the JEC Group in Paris in Hall 5 at Stand D107 of the Saxon Textile Research Institute e.V. (STFI).Together with its partners Cetex Institut gGmbH, Chemnitz University of Technology - Institute of Lightweight Structures (IST), LSE-Lightweight Structures Engineering GmbH, it will be at the joint stand of Wirtschaftsförderung Sachsen GmbH and looks forward to seeing you there!

The region of renewable raw materials: Central German Alliance for Bioplastics

The development of sustainable plastic solutions is rapidly gaining importance in light of global environ- mental pollution, dwindling fossil resources and ambitious climate protection targets. As part of the re- gional alliance RUBIO, which brings together 18 partners from central Germany and the Berlin-Branden- burg area, the bio-based and biodegradable plastic polybutylene succinate (PBS) was comprehensively investigated, starting with the raw material, through the manufacturing process, to industrial application.

17th Colloquium on Recycling for Textiles with accompanying trade exhibition in Chemnitz

On 3 and 4 December 2025, the 17th colloquium on recycling for textiles will take place at the Hotel Chemnitzer Hof. The event brings together experts from industry, science and research to present and discuss current developments, technologies and business models for a sustainable circular economy in the textile industry.

Kendyr as a climate-friendly cotton alternative: STFI explores new value chains for salinised land in Central Asia

In large parts of Central Asia, decades of cotton irrigation have led to severe soil salinisation, with serious consequences for soil fertility and the future of cotton cultivation. An international research consortium, including the Saxon Textile Research Institute (STFI), has therefore investigated the potential of alternative fibre plants. The focus was on Apocynum spp. (kendyr), a bast fibre plant that can thrive on saline soils. The aim: to restore the agricultural use of former cotton fields and establish new textile value chains in the region.

JEC WORLD 2026 opens: Paris becomes the World Capital of composites

JEC World 2026 opens tomorrow, March 10, at Paris Nord Villepinte, bringing together the entire composites ecosystem for three days of exhibitions, conferences, technical sessions, strategic industry gatherings, and business meetings. As the “festival of composites”, JEC World is also a destination for a broad spectrum of other professional visitors, eager to discover how these advanced materials can offer sustainable solutions to their industries.
