KARL MAYER GROUP: Natural fibre composites and knit to shape products at JEC World 2024

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

The STOLL Business Unit will be focussing on thermoplastic materials. Several knit to shape parts with a textile outer surface and a hardened inner surface will be on display. The double-face products can be made from different types of yarn and do not need to be back-moulded for use as side door panels or housing shells, for example. In addition, the ready-to-use design saves on waste and yarn material.

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.

Grünes Snowboard mit JEC Innovation Award ausgezeichnet

Naturfasern und Rezyklate sind die Grundlage der neuesten Produktlinie von silbaerg Snowboards. silbaerg fertigt seit 2011 hochwertige Snowboards mittels patentierter A.L.D.-tech®. A.L.D. steht für anisotropic layer design und ermöglicht eine bisher ungesehene Anpassungsfähigkeit an verschiedene Fahrsituationen.  

Handgefertigte A.L.D.tech®-Lagen umgeben den Holzkern und nicht, wie bei anderen Anbietern üblich, klassische industriell gefertigte Bi-, Tri- oder Quadraxialgelege. Bereits 2015 wurden dabei erstmals Naturfasern in Form von Tapes verwendet.

silbaerg setzt auf den Einsatz regionaler Produkte. So kommen Hanffasertapes von Sachsenleinen GmbH (Markkleeberg, Sachsen) zum Einsatz, deren Rohstoff seinen Ursprung auf den Feldern zwischen Chemnitz und Leipzig hat. Für die Versteifung der Boards werden weiterhin Carbonfasertapes benötigt. Hier greift silbaerg auf Forschungsergebnisse des Sächsischen Textilforschungsinstitutes e. V. (STFI) in Chemnitz zurück: Carbonfaserabfälle von silbaerg werden in Form von Recyclingvliesstoffen wiedereingesetzt. Die Verschnittreste, die bei silbaerg in der Produktion anderer Boards anfallen, werden am STFI auf der Anlagentechnik des Zentrums für Textilen Leichtbau aufbereitet und zu Carbonfaservliesstoffen verarbeitet. Diese werden anschließend zu Carbonfasertapes konfektioniert und dienen zusammen mit Hanffasertapes als Verstärkungsstruktur im grünen Snowboard, die damit absolut made in Saxony sind.

Aktuell werden erste Boards von silbaerg-Teamfahrern im Schnee getestet. Diese Testboards nutzen ein neues biobasiertes Harzsystem der bto-epoxy GmbH (Amstetten, Österreich), welches einen Bio-Anteil von 31 % im Harz und 54 % im Härter aufweist. Es ist geplant, die neue Produktlinie noch im Jahr 2024 auf den Markt zu bringen.  

Durch den Einsatz von Hanffasern und recycelten Carbonfasern und die damit verbundene Substitution von Primärmaterial werden Ziele für eine nachhaltige Entwicklung erfüllt. Durch die Nutzung von hauseigenen Rezyklaten lässt sich zudem die Abfallmenge von Carbonfasern im Unternehmen um ca. 75 % reduzieren. Welchen Einfluss dies auf die LCA der Produkte hat, wird aktuell berechnet.

the value chain into five parts:
• Background, LCA, circular economy ;  
• Concept, design, raw materials ;  
• Production, processes, waste ;  
• Recycling, recovery ;
• Applications.

GREENBOATS, Sicomin and Bcomp Selected as JEC Innovation Awards 2021 Finalists

GREENBOATS, Sicomin and Bcomp are nominated as finalists for the JEC Innovation Awards 2021. The three project partners have been selected as finalists in the awards’ Renewable Energy category for their innovative Green Nacelle – the first offshore nacelle manufactured with natural fibre composites (NFC).

The Green Nacelle was designed by NFC innovators GREENBOATS, who were also responsible for the structural engineering, manufacturing and assembly of the nacelle.  By incorporating Bcomp’s ampliTex™ flax reinforcements, FSC certified balsa wood cores and bio-based resins, the Green Nacelle’s NFC construction saves approximately 60% CO2 equivalent and reduces the energy consumption by over 50% compared to a nacelle made with existing GFRP technology.

In addition to the lower CO2 footprint, the natural fibre composite structure also introduces viable options for the end of the nacelles’ life unlike traditional GFRP structures - an issue of increasing concern for the wind energy sector that presents a great opportunity for natural fibre composites to bring a sustainable change to this market.

Winner: CSIR National Aerospace Laboratories (India)

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.
