From the Sector

Zur INDEX in Genf, vom 19. bis zum 22. Oktober 2021, präsentiert die GKD Gruppe (GKD) ihre Vliesstoffformierung, -trocknung und -verfestigung sowie Polymerfiltration. Im Mittelpunkt des Messeauftritts zur einer der größten globalen Vliesstoffmessenm stehen neue Produkte für Meltblown-, Airlay- und Spunbond-Vliesformierung. Außerdem stellt die technische Weberei dem Fachpublikum die Weiterentwicklung der in anspruchsvollen Thermobonding-Prozessen seit 2016 bewährten Glashybrid-Gewebebänder vor. Auch maßgeschneiderte Filtermedien aus Metallgewebe für Zentralfilter, Spinnbalken und Anblassiebe für die Polymerfiltration werden auf der Messe präsentiert.

Airlay- und Meltblown
Mit dem neuen Prozessbandgewebe CONDUCTIVE 2215 ergänzt GKD das Spektrum an Bändern für die Vliesformierung. Diesen Gewebetyp kennzeichnet eine Kreuzköperbindung aus speziellen Polyester-Filamenten. Durch ein Zusammenspiel von Materialwahl, Filamentdurchmesser, Bindungstechnologie und Luftdurchlässigkeit entsteht eine optimale Gewebeoberflächentopografie für die Vliesablage.

Spunbond-Vliesformierung
Mit CONDUCTO® 7690 präsentiert GKD auf der INDEX eine Gewebekonstruktion aus Polyester-Monofilen und metallischen Multifilen. Die webtechnisch auf der Bandrückseite eingebrachten Metallfasern haben keinen Kontakt zum Produkt. Das qualifiziert diesen Gewebetyp auch für die risikofreie Produktion anspruchsvoller Medizin- oder Hygieneprodukte. Gleichzeitig gewährleistet das ebenso robuste wie flexible Garn aus Edelstahlfasern eine bis zu zehn Mal höhere Ableitung elektrostatischer Aufladung als herkömmliche Bänder.

Converting: Spiralbänder
Mit Spiralbändern aus eigener Fertigung bietet GKD eine Lösung für Anwendungen, die beispielsweise  für breite oder schnelllaufende Anlagen der Hygienevliesindustrie geeignet sind.

Thermobonding: Antihaftbeschichtetes Glashybrid-Gewebe
In Doppelbandöfen sind die Glashybrid-Gewebebänder bei der thermischen Verfestigung von hoch voluminösen oder stark verdichteten Produkten geeignet. Querstabilität und vollständige PFA-Beschichtung qualifizieren sie für stark klebende Produkte ebenso wie für Anlagen mit großer Arbeitsbreite oder Produkte mit starken Schrumpfkräften. Als einlagige Gewebekonstruktion mit Edelstahldrähten in Schussrichtung und Kettseilen aus Glasfaserlitzen sind sie außerdem energieeffiziente Leichtgewichte - wahlweise magnetisch oder nichtmagnetisch ausgelegt.

Polymerfiltration: Lange Standzeiten durch Metallgewebekonstruktionen
Die prozessabhängige Gewebeauslegung gewährleistet hohe Schmutzaufnahmekapazität, feine Abscheideraten und geringe Verblockungsneigung. Langfilter oder Ronden aus anwendungsindividuell abgestimmten Gewebelagen optimieren im Spinnbalken die Filtration des Schmelzflusses.

The MS Ultrasonic Technology Group is a globally recognized technology and innovation leader in ultrasonic joining technology and develops and builds flexible special machines, pioneering series machines, modular systems and efficient components for high-performance complete solutions.

This enables optimal welding, punching, sealing, cut-off welding and riveting of thermoplastics, textiles and nonwovens as well as cutting of food and other products.

To ensure sustainable growth, MS is focusing on expanding its application portfolio and entering new market segments. MS Ultrasonic Technology Group is part of the listed MS Industrie AG with internationally active companies.

In addition to the company's previous activities, MS is now placing a new focus on the continuous welding of nonwovens and other materials.

More than 30 years of experience in the development and production of high-quality and innovative ultrasonic components, coupled with know-how in drive and control technology, will be incorporated into the new business segment. This means that customers receive ready-to-integrate systems with maximum precision from a single source. With the new MS Competence Center in Ettlingen (Germany), MS is fulfilling the wish of many customers to expand its application portfolio to include continuous joining, embossing and perforating of nonwovens and sealing of packaging.

MS is thus adding an innovative and specialized site, while maintaining a high level of vertical integration and support for all specialist areas through its main site in Spaichingen (Germany). In two application laboratories and a measurement and analysis laboratory, tests, evaluations and optimizations of various welding tasks are just as much a part of the service as the in-house production of engraving rollers through to complete systems.

• Application engineering consulting for your welding task
• Support in the design of the engraving roll
• Execution of feasibility studies
• Welding tests to determine the process parameters
• Individualized process optimization
• Finding solutions for problematic welding applications
• Testing of quality-describing characteristics (tightness, porosity, strength)
• Microscopic analysis of the welded joint in 3D
• Sample creation and pre-series production

Composites Evolution Ltd has teamed up with leading natural fibre reinforcement specialists Bcomp to launch a new range of flax-epoxy prepreg materials, designed to offer enhanced sustainability without compromising on performance.

Evopreg ampliTex™ prepregs combine Composites Evolution’s high-performance Evopreg epoxy resin systems with Bcomp’s award-winning ampliTex™ flax reinforcements, to deliver a family of materials which offer outstanding performance for component applications.

To reach the full performance of natural fibres, Evopreg ampliTex™ prepregs have been tailored to be compatible with Bcomp’s powerRibs™ reinforcement grid, enabling the same stiffness and weight as thin-walled monolithic carbon fibre parts while decreasing the CO₂ footprint by 85% and improving safety thanks to a blunt braking behaviour without dangerous debris or sharp edges.

Composites Evolution’s Sales & Marketing Director, Ben Hargreaves, explains further.
“Sustainability is an increasingly important factor for many of our customers - particularly those involved in motorsports and high-performance automotive applications. As you’d expect in these sectors though, sustainability can’t come at the expense of performance the two must go hand-in-hand. This is something that other prepreggers can struggle with, as natural fibres behave very differently to carbon or glass, for example.”

Customers would be able to understand the strengths and weaknesses of natural fibre composites, and to show where and how they can be adopted without the need for significant changes to existing composite component production processes.

One such customer is Retrac Group, whose composites division is one of the UK’s most experienced composites engineering companies across motorsports, automotive and aerospace. It recently used Evopreg ampliTex™ + powerRibs™ to produce a demonstrator bonnet panel for a race-bred supercar. Project Manager Alan Purves explains.

“We’re seeing a growing interest in flax fibre composites, particularly in the motorsports and niche vehicle sectors. It is therefore essential that we have developed an in-depth understanding of the processing requirements and performance capabilities of these materials, and are ready to respond to our customers' requirements. Being able to tap into the combined expertise and experience of both Composites Evolution and Bcomp is proving invaluable.”

• Testing and development achieve rigidity and safety milestone

Basaltex, pioneers in innovative uses of basalt fibres, has achieved a significant milestone in developing and testing a new composite material solution comprising fibres of basalt combined with EconCore’s patented honeycomb technology.

This new material development has greatly improved fire resistance and is highly rigid, as well as the usual honeycomb properties of light-weighting.

The company has tested the composite of basalt fibres, a bio resin and rPET honeycomb.

Filaments of only stone fibres are extruded at a temperature of 1450°C, similar to glass but with a number of advantages, not least the absence of boric acid in the process.

Combining this ecological fibre with EconCore’s sustainable technology using rPET, and the bioresin polyfurfuryl alcohol - 100% derived from a waste stream of sugar cane - make this a very sustainable and environmentally friendly product, unlike the majority of thermoset solutions in this type of application.

Railway applications require materials with enhanced fire resistance and the testing has shown that the EconCore-Basaltex solution fits these needs well, at the same time offering the perspective of drastic weight reduction against traditional monolithic GRPs used rather widely in train interiors.

Such sandwich panel could be deployed in applications such as cladding panels, partitions, tables and flooring. The thermoset skin layers give a fast cure at elevated temperature, meaning short cycle time and enabling automated production’.

As well as the railway interior application, this new material combination could be used in any application that requires fire performance combined with a low weight.

Solid net profit and further strengthening of the balance sheet thanks to significant revenue and profitability increases

The automobile industry recovered significantly in the first half of 2021 compared to the prior-year period, which had been impacted by the effects of the coronavirus pandemic. Autoneum benefited from the market dynamics and managed to increase its revenue in local currencies by 24.3% in the first semester. EBIT rose to CHF 44.7 million thanks to higher revenues and further progress in the turnaround in North America, corresponding to an EBIT margin of 5.0%. The strong free cash flow of CHF 67.2 million has allowed for a further reduction in net debt.

In the first half of 2021, 29.2% more light vehicles were produced worldwide than in the coronavirus-hit first half of 2020. The market recovery, though significant, was hampered by the global semiconductor shortage, which led to temporary production stoppages and manufacturers producing lower vehicle volumes. Autoneum increased revenue in local currencies by 24.3% in the first six months. In Swiss francs, revenue climbed by 21.9% to CHF 890.3 million. Business Group SAMEA (South America, Middle East and Africa) grew clearly above market, while the shortage of semiconductors in North America in particular impacted the production of models supplied by Autoneum and the revenue development of Business Group North America.

Autoneum managed to improve its operating result (EBIT) considerably by CHF 76.5 million in the first six months compared to the prior-year period. In addition to higher revenues, this was mainly due to the immediate and sustainable adjustment of the cost structure in all Business Groups to the new market reality in 2020 as well as the improved earnings achieved in the turnaround program in North America. Higher material costs, however, had a negative impact on the operating result. EBIT in the amount of CHF 44.7 million (prior-year period: CHF –31.8 million) corresponds to an EBIT margin of 5.0% (prior-year period: –4.4%).

The development of global light vehicle production in the second half of 2021 remains uncertain due to the semiconductor shortage. Although there is a high demand from end customers in all regions, it can be assumed that the shortage of chips will continue to impact automobile production in the second half of the year, but not as severely as in the second quarter of the first half-year.

Revenue in the second half-year 2021 is expected to be higher than in the first semester. Based on the unfavorable allocation of semiconductors to vehicle models supplied by Autoneum in the first half of 2021, revenue development is likely to be slightly below market for the full year 2021. With an easing of the semiconductor shortage, this will normalize.

Truetzschler Nonwovens will deliver equipment to enlarge an existing spunlacing line - put into operation in 2015 at the Turkish Eruslu Nonwovens Group - into a flexible, state-of-the-art production line for various light to heavy weight sustainable nonwovens.

Last year Eruslu decided to broaden its portfolio in the wipes segment by adding biodegradable products from renewable resources. The group took full advantage of the 2015 small capacity line and went for:

• a second NCR random and a NCA airlay card
• fiber preparation and card feeding equipment for the two new cards
• more hydraulic power to reliably and efficiently hydroentangle multi-layer webs
• an extension to the dryer for increased evaporation capacity

After starting up in the second half of 2022, Eruslu will be operating an ultra-modern, highly flexible NCR-NCA-NCR spunlace line, the first of its kind in Turkey. The line is tailor-made to process virgin cotton fibers, comber noils and short fibers at high speeds. End products are top-quality, lightweight natural wipes or heavy-weight, three-layer nonwovens for cosmetic pads.

COBRA International is pleased to confirm its continued partnership with Fliteboard as the builders of the new Fliteboard Series 2.  

Conceived in 2016, the Fliteboard range of electric foiling surfboards has established a leading position in the eFoil market. In early 2021, Fliteboard announced a package of evolutionary improvements to the original award-winning design for which COBRA has installed significant additional manufacturing capacity.

With Fliteboard growing rapidly, and thousands of boards now delivered across more than 80 countries,  COBRA will continue to support Fliteboard with additional moulds and lean manufacturing production lines added to reduce customer lead times. In addition to this production capacity expansion, COBRA has successfully met the technical challenges set by the Fliteboard team to incorporate all the new Series 2 board features into the existing production processes.

Fliteboard’s first composite models used a carbon fibre and Innegra sandwich laminate over a moulded EPS foam core, combining maximum strength, stiffness, and durability with a low overall board weight. The same construction concept is used for the Series 2 boards, with several new finishes added to the range along with lighter colour matched EVA deck pads and upgraded latches on the carbon fibre board lid. New wood grain and metallic paint finishes have been introduced with COBRA’s semi-transparent paint system used to save weight and display the stunning hexagonal weave pattern of the carbon and Innegra reinforcement fabrics.

Hexcel, a global leader in advanced composites technologies, announces the successful maiden flight of a lightweight camera drone, developed using Hexcel HexPly® carbon fiber prepregs. The composite drone was developed by a team of students from the University of Applied Sciences Upper Austria in Wels with composite materials supplied by Hexcel Neumarkt in Austria.

A team of six students in the university’s lightweight construction and composite materials course was responsible for the complete design, engineering, and manufacture of the camera drone over a period of 18 months. Hexcel materials and optimization of the composite engineering enabled the team to reduce the composite structural mass by an impressive 42% compared to similar drones.

Hexcel Neumarkt was one of eight industrial partners supporting the university team throughout the project, providing all carbon fiber prepreg materials used for the drone’s landing gear as well as the fuselage. The ultra-lightweight 32g landing gear was laid up and cured in the press, whereas the fuselage was autoclave cured by the student team using Hexcel HexPly M901 and HexPly M78.1 prepreg resin systems with a combination of woven and unidirectional carbon fiber reinforcements.

With the development of Unmanned Aerial Vehicles (UAV) as a key emerging market and innovation space in the transportation sector, Hexcel’s collaboration with the University of Applied Sciences Upper Austria team not only creates an important link with the next generation of lightweight composite engineers but also highlights the weight saving and structural benefits of Hexcel composite material solutions.

"The massive weight saving achieved with their updated version of the camera drone is a fantastic achievement by the student team," said Michael Rabl, Dean of FH Wels of the Upper Austria University of Applied Sciences. "The joint study not only illustrates the wide range of complex and innovative composite techniques present in the drone sector but also presents the opportunities that exist for further development in the wider Urban Air Mobility (UAM) and aerospace composites markets.”

Hexcel congratulates the project team which includes Lukas Weninger, Karl-Heinz Schneider, Jakob Schlosser, Matthias Thon, Marla Unter, and Simone Hartl on an exceptional piece of lightweight composite design and thanks them for showcasing the contribution of Hexcel materials with a presentation and drone flight. Johanna Arndt, research and technology group leader at Hexcel Neumarkt, said, “It was a great pleasure to work with the team who were very cooperative and self-motivated to succeed. Watching the drone just fly around the Neumarkt plant was just great.”

Hexcel manufactures a complete range of carbon fibers, dry carbon UD tapes, specialty reinforcements, prepregs, and honeycomb core materials, providing customized manufacturing options for new UAM applications that combine aerospace reliability with the high-rate production required. Hexcel composite materials are the ideal solution for the lightest and most efficient cost-competitive transportation vehicles of the future.
