From the Sector

Fibre Extrusion Technology Ltd (FET) of Leeds, UK has appointed Dr Kristoffer Kortsen as Senior Materials and Process Scientist. He will report directly to R&D Manager, Dr Jonny Hunter, who joined FET in early 2023 in a growing Research and Development team.

Kortsen’s main area of work is in Gel Spinning of UHMWPE (Ultra-High Molecular Weight Polyethylene). His contribution will help provide gel spinning expertise and equipment in the near future to a range of industries including medical, aerospace, defence aerospace and marine.

He completed a Master’s in chemistry at KU Leuven, graduating magna cum laude in 2018. For his Master’s placement, he worked on the production of impact modifier additives for PVC at Kaneka Belgium. Continuing a partnership with this international chemical manufacturing company, he joined the Howdle group at the University of Nottingham for a PhD project looking into the industrial potential of scCO₂ dispersion polymerisations for additive production. After graduating, he worked in the Shaver group at the University of Manchester, developing a holistic approach to plastics recycling and sustainability across the many stakeholders in the field.

Faster and more cost-effective carbon fibre production - the technology of the start-up CarboScreen comes a good deal closer to this dream. The founders Dr. Musa Akdere, Felix Pohlkemper and Tim Röding from the Institut für Textiltechnik (ITA) of RWTH Aachen University are using sensor technology to monitor carbon fibre production, thereby doubling the production speed from the current 15 to 30 m/min in the medium term and increasing turnover by up to €37.5 million per year and system. This ground-breaking development also impressed the jury at the ITMF at their Annual Conference in Keqiao, China, and was honoured with the ITMF StartUp Award 2023 on 6 November 2023.

Dr. Musa Akdere accepted the award on behalf of the CarboScreen founding team.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Both types of damage cannot be optimally detected by current means or only become apparent after production, to name just two examples. This leads to higher production costs. In an emergency, faulty production can even lead to plant fires. For this reason, and to ensure good production quality, the system is run at 15 m/min below its production capacity for safety reasons. However, 30 m/min or more would be possible. With the sensor-based online monitoring of CarboScreen, the production capacity can be doubled to 30 /min. This would lead to higher production, resulting in lower manufacturing costs and wider use of carbon fibres in mass markets such as automotive, aerospace and wind energy.

•    First production supercar created with Hypetex coloured carbon fibre
•    Paint-replacement technology reduces weight to enhance performance

British car manufacturer Briggs Automotive Company (BAC) has created a unique Hypetex coloured carbon fibre version of its Mono R, reducing the weight by removing the need for paint.  

The original BAC Mono R was created to be lighter and more powerful than the standard model, with 343bhp and 555kg total weight, equating to a power-to-weight ratio of 618bhp-per-tonne. By removing the need for paint coatings in this version, the net weight of the exterior is reduced compared to a painted shell, resulting in a further improved overall performance.

The car’s body was created using Hypetex’s titanium carbon fibre twill, and finished with a crystalized lacquer, offering a unique aesthetic finish. The ultra-lightweight supercar can accelerate from zero to 60mph in less than 2.5 seconds.  

Hypetex’s paint-replacement technology retains the visible weave, allowing for a bold design and a choice of colours without technical compromises, perfectly aligning with BAC’s initiatives to maximise performance whilst creating bespoke supercars. Paint generally adds 138 grams per metre squared, whereas Hypetex adds just 17 grams for the same area, offering an 8x weight saving.
This bespoke version of BAC’s single-seater Mono R was subject to BAC’s renowned BAC Bespoke programme, which ensures that no two Monos are the same. The client, a US-based collector, worked with BAC’s design team to design the car to their personal taste.   

Born out of Formula 1 technology, Hypetex offers manufacturers sustainable aesthetic materials with technical and efficiency benefits. This collaboration is an all-British success story, with the Hypetex carbon fibre body built by Formaplex, a leading UK-based manufacturing company who manufacture lightweight engineered solutions for top tier customers in Automotive, Aerospace and Defence markets. BAC’s supply chain is 95% UK-based.  

Hypetex continues to expand its growing portfolio of the use of coloured carbon fibre to add personalisation to the automotive field, with its material recently featured on the 2024 Ford Mustang Dark Horse.  

Harnessing the synergy of the Texpertise Network of Messe Frankfurt and its global apparel flagship, the co-organisers of the Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) recently held a joint press conference on 28 August 2023, the first day of Intertextile Shanghai Apparel Fabrics – Autumn Edition. Discussing the inaugural fair’s comprehensive, business-friendly nature, representatives of both Messe Frankfurt  and VIETRADE spoke in glowing terms about the potential of ASEAN’s new platform for the entire textile industry.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

HEATHCOAT FABRICS partnered again with BRÜCKNER Textile Technologies and their sales partner ADVANCED DYEING SOLUTIONS to install a finishing line for industrial textiles. HEATHCOAT FABRICS specializes in the production of technical textiles in the fields of texturising, weaving and warp knitting as well as dyeing and finishing. The prroducts are manufactured for use in the automotive, healthcare, defence, and aerospace industries

Mrs. Regina Brückner, CEO and owner of the BRÜCKNER Group stated: "To meet the complex re-quirements of HEATHCOAT is not easy because of the great variety of technical textiles produced. Our line has to finish light as well as heavy articles, so the design, control and the whole line layout have to be flexible, functional and still easy to operate. Fortunately, the team at HEATHCOAT FABRICS is very innovative and open-minded, and together we worked hard to develop the right technology and han-dling. We are very happy that we could convince this customer, whom we appreciate very much, with the productivity of our line and of course with our technological know-how."

The unit is equipped with a low-lub, horizontally returning combined pin / clip chain and several fabric paths, especially designed for the different fabrics being processed. Together with HEATHCOAT FABRICS technologists, the BRÜCKNER design team developed a special delivery end of the stenter with different edge trimming and slitting possibilities. Depending on the kind of products, the fabrics can be batched on large diameter A-frames, wound on cardboard tubes or plaited into trolleys.

Monforts will highlight its technologies for special technical textile applications at this year’s ITMA ASIA + CITME which takes place at the National Exhibition and Convention Center in Shanghai, China, from November 20-24.

One of Monforts' developments is the Montex 8500 XXL stenter system for the production of technical fabrics in widths of up to 6.8 metres. Among the products made on this system are treated nonwovens for the geotextiles and filter media markets, tarpaulins, advertising banners, black-out curtains, membranes and many more.

On Montex©Coat coating lines, meanwhile, the possibilities range from the single-sided application of finishing agents for outdoor clothing and adding functionality to home textiles, to the creation of materials for sophisticated lightweight construction and automotive and aerospace components.

“Many more applications are possible, such as the overdyeing of denim, the creation of double-face coated materials, fabrics awnings, tents and medical drapes and the pre-treatment of substrates for digital printing”, explains Gunnar Meyer, Monforts area sales manager for China. “A range of different doctor blades and their combinations can be supplied to meet individual requirements, including air knife, roller knife, foam, screen and magnetic roller coating. The latter option is recommended for lines with working widths of over 2.4 metres.”

In addition, Monforts can provide the necessary explosion-proof ranges for solvent-based coatings and high temperature processes up to 320°C, such as the PTFE coating of nonwoven filter material. These lines are equipped with special burners, stenter chains, and insulation.

Hexcel has leveraged its experience in aerospace and wind energy to develop its new G-Vent technology for OoA processing of highly loaded, thick section marine structures such as masts, foils, and wind-assisted ship propulsion (WASP) components. A full range of Hexcel marine prepregs are now available with integrated G-Vent technology, reducing the requirement for debulking steps and ensuring extremely low porosity (<1%) regardless of the laminate thickness. Leading marine non-destructive testing specialists Q.I. Composites recently confirmed that the thick section G-Vent panels they had evaluated had void contents and laminate quality in line with state-of-the-art autoclaved prepreg components. Visitors to the Hexcel stand will see a unique 400mm carbon cube cured in a single stage using 695 layers of HexPly M79 carbon fiber UD600 prepreg with G-Vent technology.

New HexPly® Nature Range Sustainable Prepregs
HexPly® Nature Range prepregs feature proven resins such as HexPly M49, M78 and M79 with bio-derived epoxy resin content. Created for use in all industrial markets, HexPly Nature Range materials can be seamlessly integrated into existing production processes, maintaining consistent mechanical performance and processing properties. A dedicated sustainability corner of the Hexcel stand will detail Nature Range products optimized for automotive, marine, wind energy and winter sport applications. The display will include an alpine ski produced by leading manufacturer Tecnica Group Ski Excellence Center which produces skis for Blizzard and for Nordica using HexPly Nature M78.1 UD flax prepreg material. In addition to the reduced environmental impact of the sustainably grown reinforcement, the flax fiber laminates also improve impact resistance and vibration damping in the ski.

HexPly® XF Surface Technology for Improved Part Surface Finish Quality
HexPly XF is a lightweight, semi-preg material that replaces traditional in-mold gel coat. It eliminates time-consuming refinishing work typically required to obtain a paint-ready surface and produces lighter, more consistent parts with shorter cycle times and a cleaner working environment. Visitors to the stand will see a composite panel illustrating a high-quality painted surface enabled with XF technology in a diverse range of industrial applications such as super yacht roof parts, Class A surface automotive panels, and both prepreg and infused wind turbine blades.

HexPly® M49 Prepreg for Automotive Visual Carbon Parts

Sicomin has confirmed that eco-surfboard specialist NOTOX will use GreenPoxy 56 in its latest line of R-CARBON boards. The new NOTOX R-CARBON boards are the first to use 100% upcycled carbon fibre fabrics recovered from a production waste stream at Airbus.

NOTOX, founded in 2006 and based in Basque, France, has partnered with Sicomin to use GreenPoxy bio-resins in several earlier flax, cork, and bamboo reinforced boards. In a quest to now produce the most sustainable carbon fibre reinforced boards possible, NOTOX has signed a formal agreement with Airbus Nantes to purchase defective carbon fabrics that were destined for landfill.

The new NOTOX technology gives a second life to Airbus carbon fabrics that are declared unusable for aerospace applications due to short roll lengths, an inability to be pre-formed, or other defects. The upcycled materials are combined with Sicomin GreenPoxy 56 and Surf Clear hardener, producing an extremely clear, high gloss laminate with high mechanical properties. NOTOX use a precisely controlled wet lamination process with vacuum bag consolidation to wet out the upcycled woven carbon fabrics and minimise resin consumption in the manufacturing process.

In addition to selecting a high bio-content resin – GreenPoxy 56 derives 56% of its carbon content from plant sources – NOTOX has also sourced the most sustainable carbon fibre fabrics. Full life cycle analysis by NOTOX has shown that using waste carbon fabrics from Airbus is significantly more energy efficient than using other recycled short fibre carbon, confirming the importance of upcycling this key raw material.
