From the Sector

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.

• JEC Forum DACH: a primising agenda highlighting composites innovatioon in the region

September 7, 2021 - JEC Forum DACH's primary goal is to promote the region DACH area's dynamic composites ecosystem through a promising program that includes conferences, startup competition, and awards. The first edition of the JEC DACH Forum, unique in its format and content, will occur in the Forum of Messe Frankfurt from November 23 to 24, 2021.

For two days, the JEC Forum DACH program will offer the opportunity to exchange and learn about the current and future developments of Composites in the DACH region through a rich program of conferences, the JEC Composites Startup Booster, and the JEC-AVK Awards. JEC Forum DACH will include pre-arranged Business Meetings between sponsors and attendees as well as sponsors' workshops. Advance registration is required to attend this forum that expects to gather 500 participants.

Conferences, keynotes and market overview

JEC Forum DACH will feature cutting-edge live conferences with exclusive keynotes organized by the AVK.
The composites industry provides a significant impetus, e.g. in its process technologies for hybrid structures or integrated manufacturing and modern mobility or new materials in the booming construction sector. There's been an increasing number of marketable ideas for recycling and sustainability solutions. Furthermore, an exclusive report on current market developments in the European composites market will be delivered.

JEC Forum DACH will also feature a fulfilling conference program with experts from the industry giving insights on the latest developments in high-performance composite technologies and applications.

Each day of the forum will be broken down as-is:
•    Two keynote speeches led by one or two high profile experts
•    Conferences/technical presentations
•    Workshops and Business Meetings

Please find the program of the conference attached.

Peter D. Dornier, member of the Executive Board of the VDMA Textile Machinery Federation and Chairman of the Walter Reiners Foundation for the Promotion of Young Engineers, honours five young talents. Numerous entrepreneurs and managers from the German textile machinery industry took part in the award ceremony at the Digital Capability Center (DCC) in Aachen, Germany.

The prizewinner in the dissertation category, Dr.- Ing. Benjamin Weise, comes from the Institute of Textile Technology at RWTH Aachen University (ITA). He has dealt with a complex production process for the manufacture of modified multifilament yarns, which offers new perspectives for the development and manufacture of textile charge carriers.

M.Sc. Susanne Fischer, winner of the Master's thesis category, has systematically and comprehensively solved the challenging task of integrating motion sensors into a finger glove at Reutlingen University.
The 2018 creativity award winners are team Mr. Jan Merlin Abram and Mr. Alon Tal from ITA Aachen as well as Mr. Eric Otto from the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) in Dresden. The students Abram and Tal have developed a guideline for the design of hybrid morphing textiles. In addition to the classic functions in conventional and, in particular, composite applications, locally defined, functionally effective joint, torsion, expansion and compression mechanisms can be integrated into the textile.

The prizewinner Otto is awarded for a concept study for the development of a circular knitting machine with a variable diameter needle cylinder, which can lead to further flexibility in the circular knitting process.
