• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

Textechno reports launch of a new standard for the drapability and deformability of fabrics and non-wovens: ISO 21765

World market leader for precision testing equipment Textechno and their partner SAERTEX, global market leader in non-crimp fabrics (NCF) are proud to announce that the newly developed international standard ISO 21765:2020 to quantify material behaviour in terms of drapability and deformability was recently published by ISO.

The new standard ISO 21765 allows the world-wide comparable measurement of all relevant parameters regarding the deformability and drapability of all kinds of fabrics, including woven fabrics and NCFs as well as knitted fabrics and non-wovens on Textechno´s precision testing equipment DRAPETEST. This can be very useful in the carbon fibre recycling since one of the most efficient applications of recycled carbon fibres will be in non-wovens.

This is the first testing instrument world-wide to quantify not only the force which is required for deforming a fabric, but also the various defects such as gaps, undulation, or wrinkles which can arise due to the deformation.

In the frame of a publicly funded project which started in 2011, Textechno developed the award-winning automatic drapability tester DRAPETEST along with other partners, amongst them SAERTEX.  

Dietmar Möcke, CTO at SAERTEX says: „With ISO 21765, we finally have a standardized testing method with world-wide validity. It allows us to provide our customers with comparable and reproducible measurement values regarding the draping characteristics of our products.”

Ulrich Mörschel, Managing Director of Textechno adds: “We are grateful for the support from all around the world allowing us to establish the new ISO standard. The standard finally fills a gap in the testing methods for fabrics both in the fields of textiles and composites.”

Dr. Michael Effing, Managing Director of AMAC GmbH and Senior Advisor to Textechno: “A lot of research is dedicated to new production technologies of composites, non-crimp fabrics and classical fabrics for thermosets have with 33 % a significant market share in the production of all composite materials. The application of the new standard for non-wovens from recycled carbon fibres comes perfectly on time for this market sector which will gain more and more importance within the next years.

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.

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.”

TCV, Teijin’s carbon fiber business base in Vietnam, was established in May 2019. Teijin Limited announced that Teijin Carbon Vietnam Co., Ltd. (TCV) in Ha Nam, Vietnam, has started operating commercially to manufacture carbon fiber products including prepreg, a fiber sheet pre-impregnated with matrix resin as an intermediate material for composites. TCV initially will produce carbon fiber materials for sports and outdoor activities, including fishing, golf, bicycle and ice hockey goods, for markets in Southeast and South Asia and Asia-Pacific. Sales will be handled by TCV as well as carbon　fiber sales affiliates of Teijin operating in these markets.

Teijin’s sales affiliates in Singapore, Shanghai and Taipei work to identify demand opportunities as well as provide customer services in Asia. Internal collaborations between these companies and TCV shall strengthen Teijin’s presence in the upstream and downstream sectors of Asia’s fast-growing markets.

Increasingly strict environmental measures and the upgrading of environmental frameworks, such as sustainable development goals (SDGs) and the Paris Agreement, are expected to stimulate greater use of lightweight and highly rigid carbon fiber. Demands are growing in Asia, especially in the fields of sports and outdoor activities, industry and aerospace. COVID-19, for example, has led to new trends in sports and　outdoor activities, such as renewed interest in fishing due its compatibility with social-distancing protocols.

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.

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.

Decision SA, part of the leading European composites consortium, Carboman Group, and a specialist in the development, prototyping and production of large composite structures, is proud to announce a new direct mould tooling technology for aerospace.  Decision’s latest tooling solution provides OEMs and manufacturers with short lead times for highly stable direct moulds for series production both in and outside of the autoclave at temperatures of up to 180˚C.

Decision and Carboman recently delivered the first customer moulds using the new technology, providing a tooling glass prepreg, stainless-steel backed direct female mould tool created for the series production of a Class 3 fairing to a leading European aerospace OEM. Decision has immediate availability and capacity for similar tooling projects with lead times currently as short as six to eight weeks.

With no traditional plug or mould pattern required, Decision’s direct mould process starts with the group’s engineers selecting a material combination for the tool surface and support structure that will provide the optimum match between the coefficient of thermal expansion (CTE) of the mould and the composite part to be processed.  The CNC machined composite face sheet is supported by a stress-relieved metallic or composite backing structure before final post curing and machining is completed. The principal benefit of this novel approach, aside from removing the need for costly and time-consuming plug production, is the production accuracy delivered by the closely matched CTE of the mould tool and the finished composite part.

The autoclaved composite tool surface is not only extremely dimensionally stable up to processing temperatures of 180˚C, but it can also be configured with additional metallic inserts or fixtures if required.  

Produced in an EN 9100:2018 controlled production environment, and with CMM checks before and after machining, the new direct composite tools have dimensional tolerances of +/-0.2mm.  The available tooling dimensional envelope is currently defined by Decision’s 2200mm x 6000mm autoclave.

“With our new direct tooling technology, we are able to combine the highest technical standards in dimensional accuracy and thermal stability with extremely short lead times.  Decision and Carboman Groups’ combined mission has always been to develop the construction methods for tomorrow’s composite structures, and we believe that this tooling solution will allow our customers to accelerate the implementation of the next generation of high-performance carbon fibre aerostructures and components” Grégoire Metz, Managing Director, Decision SA.
