SGL Carbon and Solvay collaborate to develop highly-competitive advanced carbon fiber composites for aerospace primary structures

SGL Carbon and Solvay have entered into a joint development agreement (JDA) to bring to market the first composite materials based on large-tow intermediate modulus (IM) carbon fiber. These materials, which address the need to reduce costs and CO2 emissions, and improve the production process and fuel efficiency of next-generation commercial aircraft, will be based on SGL Carbon’s large-tow IM carbon fiber and Solvay’s primary structure resin systems.

The agreement encompasses both thermoset and thermoplastic composite technologies. It builds on Solvay’s leadership in supplying advanced materials to the aerospace industry and SGL Carbon’s expertise in high-volume carbon fiber manufacturing.

“For Solvay, this is an opportunity to lead the aerospace adoption of a composite material based on 50K IM carbon fiber. This is a highly competitive value proposition that brings more affordable high-performance solutions to our customers. We see this as the first step in a long-term partnership,” said Augusto Di Donfrancesco, member of Solvay’s executive committee.

“By combining SGL’s carbon fiber expertise in our newly developed, unique 50K IM fiber with Solvay’s resin formulation and aerospace market expertise, both partners are aiming to develop an advanced aerospace material system. This alliance supports our strategic direction and accelerates our growth in the attractive aerospace market,” said Dr. Michael Majerus, spokesman of the management board of SGL Carbon.

Composite materials for aerospace applications represent a multi-billion-dollar market that is expected to grow strongly in the coming decade. Solvay and SGL Carbon are uniquely positioned to develop solutions to address the needs of this market.

• Glass fiber textiles for helicopter type H145
• First ever material supply for primary structural components in the aerospace segment

Since August of this year, SGL Carbon delivers two special glass fiber textiles, so-called non-crimped fabrics, for the new version of helicopter model H145 from Airbus Helicopters. These materials are used in the new, especially efficient five-blade rotor. Developed in close collaboration with Airbus Helicopters, the material has been qualified for the application for the next years to come.  

Thanks to their unidirectional fiber orientation, the fabrics are extremely resistant, providing optimal support for the new geometry of the especially long H145 rotor blades. The fabrics are manufactured at the SGL Carbon site in Willich near Düsseldorf in a multi-stage process and delivered to Airbus Helicopters in Paris.  

“The order emphasizes our growing presence in the aerospace business. With the fabrics for Airbus Helicopters, we have realized, qualified, and started serial production for a material concept for primary structural components for the first time,” underscores Dr. Andreas Erber, Head of the Aerospace segment in the business unit Composites – Fibers & Materials at SGL Carbon.

The current deliveries are part of a framework contract with Airbus Helicopters, intended to gradually intensify collaboration. Besides the current development of materials for helicopter components, Airbus Helicopters and SGL Carbon have worked together in the area of component material processing for Airbus group aircraft doors for years. In addition, Airbus and SGL Carbon are jointly involved in various associations and research projects in the area of components, such as Carbon Composites e.V.

Lighter, quieter and more environmentally-friendly vehicles ‒ this is what Hybrid-Acoustics PET from Autoneum stands for. The product innovation for the engine bay is not only characterized by its lightweight construction and noise protection optimized for electric vehicles, it also convinces through sustainability: Components made of Hybrid-Acoustics PET consist entirely of PET, which is largely obtained from recycled fibers, and thus meet customer demand for environmentally-friendly mobility solutions.

With Hybrid-Acoustics PET, Autoneum has adapted its textile interior technology Hybrid-Acoustics for use in the engine compartment. The patented innovation is based on a unique fiber material that acts as an insulator and absorber at the same time. Among others, Hybrid-Acoustics PET is used to encapsulate electric motors, thereby reducing noise directly at the source and particularly attenuating high-frequency sounds of the electric drive unit. This key technology accordingly ensures optimum noise protection in the passenger cabin and greater driving comfort.

• Organic Waste Systems and TÜV confirm fiber biodegradability also in fresh water
• All white LENZING™ Viscose, Modal and Lyocell fibers are now certified for all environments
• Global legislators aim at limiting plastic waste persisting in the environment for centuries
• EU Single-Use Plastics Directive partly regulates usage of plastic products
• Biodegradable materials such as wood-based fibers are the best alternative to single-use plastics

The Lenzing Group received confirmation of the full biodegradability of its fibers in fresh water by the independent research laboratory Organic Waste Systems (OWS). The new and existing international certifications conducted by OWS and issued by TÜV Austria verify that LENZING™ Viscose fibers, LENZING™ Modal fibers and LENZING™ Lyocell fibers are biodegradable in all natural and industrial environments: in the soil, compost as well as in fresh and in marine water.

The biodegradability of cellulosic products and the synthetic fiber polyester was tested in fresh water at OWS according to valid international standards, e.g. ISO 14851. At the end of the trial period, LENZING™ wood-based cellulosic fibers, cotton and paper pulp were shown to be fully biodegradable in fresh water in contrast to synthetic polyester fibers. The fact that synthetic materials are not biodegradable leads to major problems in wastewater treatment plants and potentially marine litter. In turn, this not only harms fish and birds living in and close to the oceans but also all marine organisms and us humans.

“The Lenzing Group operates a truly circular business model based on the renewable raw material wood to produce biodegradable fibers returning to nature after use. This complete cycle comprises the starting point of the core value of sustainability embedded in our company strategy sCore TEN and is the ‘raison d’etre’ of our company”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group. “In living up to this positioning, we not only enhance the business of our suppliers, customers and partners along the value chain but also improve the state of the entire textile and nonwovens industries.”

Both the textile and nonwovens industries face huge challenges with respect to littering. If current trends continue, the oceans could contain more plastic than fish by 2050. Therefore, legislative bodies worldwide can no longer ignore the issue and have moved towards plastics legislation aimed at limiting the vast amount of waste. In response, European lawmakers issued the Single-Use Plastics Directive currently being transposed into national legislation in the EU member states.

Conventional wet wipes and hygiene products mostly contain plastic and were thus identified as one of the product categories to be singled out. Less polluting alternatives are generally encouraged by NGOs and legislators, e.g. products made of biodegradable wood-based cellulosic fibers. Plastic waste including microplastic can persist in the environment for centuries. In contrast, biodegradable materials are the best alternative to single-use plastics because they fully convert back to nature by definition and thus do not require recycling.

A wide range of new technologies will be demonstrated by Vandewiele at the ITMA 2019 textile machinery show in Barcelona from June 20-26, including the latest RCE2+ digital carpet weaving machine.

All Vandewiele technologies are now being equipped for machine-to-machine interaction and learning, as part of the company’s comprehensive TEXconnect programme.

Meeting new industry needs
As a leader in complete carpet manufacturing systems – including BCF extrusion lines, heat setting systems and carpet weaving and tufting machines – Vandewiele has rapidly responded to the evolving needs of the textile industry for smaller and customised production runs, the most challenging of designs, and faster and more sustainable manufacturing.

The company’s sensors, software programmes and servers have become increasingly sophisticated as part of the TEXconnect program, and the real-time data from different machines – across connected manufacturing sites and across different countries and even continents – can be collected and shared. Digital models of both machines and production processes can be created and analysed for the optimisation of production settings, to vastly improve scheduling and planning and also make considerable savings in raw materials and energy consumption.

Virtual and remote control now allows for the Big Data analysis that is propelling the industry forward and will pave the way for AI applications. For carpet manufacturers, all of this is leading to the creation of truly Smart Factories.

RCE2 carpet weaving
The new RCE2+ Rug and Carpet Expert weaving machine is a truly digital workhorse, with all yarns continuously controlled and measured and the difficult bobbin changes of the past completely eliminated. This is as a result of Vandewiele’s latest Fast Creel, with the feed and tension of each pile yarn controlled by individual servomotors.

The pile yarns are now fed directly into the machine without having to pass pile-stop motions, to both increase efficiency and eliminate any waste yarns, while achieving previously unreachable industrial speeds.

The filling enters the machine smoothly via the latest IRO X3 winders, heavy duty filling brakes with multi lamellas, an active yarn recuperator and a high speed weft mixer, where again, all tensions are set electronically. Vandewiele’s servo-driven heddle frames (Smart Frames) are meanwhile already well proven in the industry.

TEXconnect further provides readily-available data on all yarn consumption, tension and threading, and then will supply the predictive maintenance that is paving the way to self-learning carpet weaving machines.

All of this would be unnecessary, if it didn’t result in allowing manufacturers to make the highest quality carpets at the most economic prices ever, with savings on the highest-bulk pile yarns from the Vandewiele extrusion lines, reduced waste yarns in the creel and industrial production speeds that have never before been attained.

The innovative technology addresses the growing need for on-demand textile design and production

Kornit Digital, a global market leader in digital textile printing innovation, has announced the introduction of the new Kornit Presto, the only industrial single-step solution for direct-to-fabric printing. The Kornit Presto solution eliminates the need for pre and post treatment of fabric and allows for high-quality printing on a broad variety of fabric types and applications. The Kornit Presto does not consume water in the printing process, making it a environmentally friendly solution.

The new Kornit Presto comes with the NeoPigment Robusto, a Pigment-based ink. Implemented into the Kornit NeoPigmentTM process, the Robusto provides above industry standard wash and rub results and exceptional color fastness across a wide fabric and application range. The Robusto enjoys faster physical and chemical bonding characteristics, enabling a significantly shorter curing time, while providing quality and a wide color gamut.

The Kornit Presto solution suits a wide range of business and application needs in a variety of industry segments, including fast growing segments within the on-demand fashion and home décor markets. It is a highly productive solution, available in multiple configurations and able to print 450 square meters per hour.

Gart Davis, CEO at Spoonflower, the world’s first web-based service for custom, on-demand fabric and design creation and a long-time Kornit customer, commented, “We were thrilled to be able to test the new system and found the Presto to be in a class by itself; it prints beautifully on all kinds of fabrics, in a single-step, with an environmentally friendly dry process, and now at a multiple of productivity.  Our partnership with Kornit continues to be fundamental to our mission to make custom fabric accessible to designers, creative individuals and small businesses all over the world. We can’t wait to get going.”

Composite reinforcement specialist Chomarat will exhibit its latest woven and multiaxial carbon fibre reinforcements at JEC World 2019. "Prepregs are used in the most demanding markets, such as aerospace or the automotive industry. Due to their high performance, Chomarat’s carbon fabrics are highly considered by prepreggers. Compared to standard solutions, the multiaxial reinforcements developed by the group offer Chomarat’s converter customers significant productivity gains. With its production sites in France, Asia and the United States, Chomarat is able to supply its customers and guarantee the same high level of quality in all countries," explains Group Managing Director Michel Cognet.

C-WEAVE™ - THE QUALITY AND RELIABILITY BENCHMARK
In just a few years, prepreggers have come to consider Chomarat's C-WEAVE™ carbon-fibre fabrics as a benchmark for surface-finish quality and processability.
The reinforcement contributes to productivity and reliability during the prepregging process. Helen Doughty, Director at SHD Composites, testifies: “The consistent high quality of C-WEAVE™ has been a key part of SHD Composite Materials continued success and growth.”
"Prepreg users often manufacture Class A surface parts for demanding applications, and they need excellence and reproducibility," explains Chomarat’s Prepreg Market Manager Ulrike Salmon.

C-PLY™: GOING FURTHER WITH CARBON MULTIAXIALS
The advantages of multi-axial reinforcements are now well established - oriented axes, absence of resin-rich areas allowing a high fibre content, and improved mechanical tensile and/or bending performance thanks to the non-crimp fibres.
By developing its C-PLY™ range, Chomarat further demonstrates that multiaxials are a real asset in terms of performance and appearance. "Chomarat strives to minimize marking on parts and to optimize surface quality through fibre spreading and the use of suitable stitches. C-PLY™ can also integrate aesthetic functions by using the assembly seam as a graphic design", continues Ulrike Salmon.
These new advantages are important for the automotive, sports-equipment and consumer-electronics markets, which seek to combine premium quality and productivity.

New products for photopolymer and laser sinter printing methods from BASF 3D Printing Solutions GmbH (B3DPS) are on show from November 13 to 16 at Stand F20 in Hall 3.1 at this year’s formnext fair in Frankfurt. The BASF subsidiary is also announcing several new partnerships for the development and distribution of groundbreaking 3D printing solutions and products.

B3DPS has entered into a strategic partnership with the US company Origin, San Francisco, California for the further development of photopolymer printing processes. “Within the framework of an open business model, we are combining BASF’s material know-how with Origin’s expertise in printer software programming and the manufacture of the corresponding hardware,” explained Volker Hammes, Managing Director BASF 3D Printing Solutions GmbH. The collaboration has already shown the first signs of success. Origin has developed a new printing method where BASF’s new Ultracur3D photopolymers can be processed particularly well. The technology offers an optimal combination of a good surface finish and high mechanical stability, while also allowing for high material throughput.

B3DPS is working together with Photocentric, a manufacturer of 3D printers and their corresponding software and materials, on the development of new photopolymers and large-format photopolymer printers for mass production of functional components. Based in Peterborough, UK and Phoenix, USA, Photocentric has developed and optimized the use of LCD screens as image generators for its own printing systems. The two partners plan to offer the industry 3D printing solutions that replace parts of traditional manufacturing processes such as injection molding for small series, as well as enabling the production of large components.

The objective of the cooperation with Xunshi Technology, a Chinese printer manufacturer headquartered in Shaoxing, and operates in USA under the name Sprintray, will be opening new fields of application in 3D printing for the Ultracur3D product range of B3DPS.

Ultracur3D specialties for photopolymer printing processes
B3DPS has grouped well-established and new photopolymers designed for the respective 3D printing processes under the brand name Ultracur3D. BASF has developed unique raw materials for its new products that enable special part properties.
“Our Ultracur3D portfolio enables us to offer customers various UV-curable materials for 3D printing that provide far better mechanical properties and higher long-term stability than most available materials,” explained András Marton, Senior Business Development Manager at B3DPS. He added: “These materials have been developed for functional components that are subject to high stress.”

Expansion of distribution network for filaments
Innofil3D, a subsidiary of B3DPS, is entering into a partnership with Jet-Mate Technology, based in Tjanjin, China, for the distribution of plastic filaments in China. In parallel, a distribution agreement has been concluded with M. Holland in Northbrook, USA for the distribution of filaments in USA. “Since the USA is the largest market for filaments, we intend to strengthen our activities there,” said Jeroen Wiggers, Business Director 3DP Solutions for Additive Extrusion at B3DPS, adding: “Asia is another important market for us. We will be developing further distribution channels there and putting our Ultrafuse filaments on the Asian market in 2019.”

BASF’s portfolio of filaments for 3D printing are comprised of two categories; the well-established Innofil3D filaments based on generic polymers for conventional applications and polymer-based Ultrafuse filaments for advanced formulations used in demanding technical applications. One of the broadest filament selections on the market, this portfolio covers customer requirements ranging from prototype to industrial-scale production.

SLS: new 3D printing material with fire protection classification
New flame-resistant Ultrasint Polyamide PA6 Black FR meets UL94 V2 fire protection standards and is a new material class for use in selective laser sintering (SLS) processes, distinguished by high stiffness and thermal stability. In cooperation with one of the global leaders of public transportation vehicles, B3DPS has developed new components that meet vehicle fire protection requirements. “Together with our partner, we are currently producing prototypes, spare parts, and small series components, and are working to further improve flame resistance to meet additional certification specifications,” explained Hammes.
BASF introduced Ultrasint Grey PA6 LM X085 at AMUG this spring and now is followed by another product on show at formnext. Ultrasint PA6 Black LM X085 is based on polyamide 6, and can be processed at 175-185 degrees Celsius therefore making it suitable for most current SLS machines.

B3DPS adds polypropylene to its 3D printing portfolio
Through the acquisition of Advanc3D Materials GmbH in July 2018, B3DPS has expanded its range with numerous materials for use on laser sinter machines, including polyamide Adsint PA12, Adsint PA11, Adsint PA11CF and Adsint TPU flex 90.
Ultrasint PP is a special highlight. This polypropylene-based product exhibits outstanding mechanical properties and is frequently used in standard industrial production as it offers a good balance between price and performance. Ultrasint PP is distinguished by excellent plasticity, low moisture uptake, and resistance to liquids and gases. Prototypes and small batches can now be produced from the same material as used for traditional serial production. Post treatments such as thermoforming, sealing, and dyeing can be performed after printing.
