From the Sector

• Carbon fibers combined with injection molding replace conventional steel construction
• SGL Carbon supplies innovative carbon fiber profiles
• Serial use in a future high-volume model of BMW Group
• Construction method offers great potential for use in other automotive projects

Already in August, SGL Carbon received a multi-year order from Koller Kunststofftechnik GmbH for the production of novel carbon fiber profiles for serial use in windshields for a future high-volume model of BMW Group.

The profiles are particularly flexible fiber tows, pre-impregnated with thermoplastic resin in various dimensions. They will be compiled by SGL Carbon on the basis of its own 50k carbon fiber at its site in Innkreis, Austria, and subsequently processed by the injection molding experts at Koller to form a skeletal plastic component. The composite component will replace the previous steel-based windshield. Production of the carbon fiber profiles will start in the remainder of 2020 and will then be ramped up gradually over the next few years for the BMW Group model launch.

In the vehicle, the windshield is a connecting element between the roof frames and thus has an important stabilizing function. The carbon fiber profiles add the required stiffness and crash safety to the component. At the same time, they help to significantly reduce the weight of the roof and thus also support the driving dynamics. The injection molding process also enables particularly complex and material-efficient structures. In the BMW Group model, this innovative component concept will cut weight by 40 percent compared to conventional steel designs of the component while creating important space for cable ducts and sensors.

The production of the carbon fiber profiles themselves is also particularly geared to material and process efficiency in large-scale production. The profiles consist of several smaller fiber strands, the so-called rods, and are manufactured using the modern continuous pultrusion process. During product and process development it was one key objective to ensure that material loss during production is almost completely avoided.

"At SGL Carbon, we have been working on the development of thermoplastic carbon fiber profiles for use in injection molding for some time already. This development work is now beginning to pay off. Due to the many advantages and competitive costs, we see a great potential for the technology to be used in other automotive projects too," explains Sebastian Grasser, Head of the Automotive Segment in the Business Unit Composites - Fibers & Materials at SGL Carbon.

"Innovative lightweight construction with hybrid designs has developed into a strategically conclusive concept for Koller Group's OEM customers," confirms Max Koller, CEO of Koller Group. "SGL Carbon's high level of material expertise, combined with the process know-how of KOLLER Kunststofftechnik and KOLLER Formenbau, create the basis for a promising future in innovative lightweight construction technologies. With this order, the BMW Group has confirmed its confidence in the successful cooperation between SGL and Koller; we are particularly pleased about this", said Max Koller.
 
The Koller Group is a globally operating technology company with plants in Europe and China, as well as NAFTA. The Koller Group develops and manufactures lightweight construction, tools and serial components, primarily for the automotive industry.

• New composite e-Mobility application
• Multi-year substantial contract

After prototypes for a Chinese automotive manufacturer, a major order from a North American automaker, and yet another order for a European sports car manufacturer, SGL Carbon has now been nominated by BMW Group to produce a cover component for battery enclosures in series. This substantial multi-year order will include the production of an innovative glass-fiber-based cover plate for the battery housing for usage in a future plug-in hybrid model of BMW Group.

Materials made of composites are suited for battery enclosures for different reasons: Besides their light weight, which enhances the electric vehicle’s range, fiber-reinforced plastics offer high stiffness. In addition, they meet high requirements for water and gas tightness and feature excellent fire protection properties. Composite materials can also help to achieve improved structural stiffness of the underbody, e.g. to protect against penetration, as well as an optimized thermal management. Carbon fibers are ideal for especially stressed structures or load-bearing elements, such as the underbody panels and side frames. For components subjected to less stress, such as battery box covers, glass fibers or a fiber mix may suffice.

In addition to the new application for the hybrid model battery enclosure, SGL Carbon will continue producing the usual components made of carbon-fiber-reinforced plastic for the BMW i3 and delivering materials for the Carbon Core body of the BMW 7 series, and has been nominated as the supplier for all carbon materials - fibers, textiles, stacks - for the BMW iNEXT, set to be launched in 2021.

Monforts Textilmaschinen GmbH & Co. KG will be providing information on its extensive range of coating and finishing technologies for the production of nonwovens and technical textiles at the forthcoming Techtextil India exhibition.

“India is already a very important market for Monforts and there are exciting prospects ahead for Indian manufacturers of technical textiles, who are well positioned to capitalise on growth opportunities,” says Monforts Head of Denim Hans Wroblowski, who will be at the Monforts stand in Hall 4, booth C52 at the show. “India has one of the largest working-age populations in the world and a complete textile value chain for both natural and synthetic fibres.”

In addition, he adds, India’s government, through its Ministry of Textiles, has been actively promoting the growth of technical textiles through various programmes based on investment promotion, subsidies, the creation of infrastructure and the stimulation of consumption.

As a result, India’s Ministry of Textiles is forecasting that the growth of technical textiles in the country will be over 18% annually in the next few years, from a value of US$16.6 billion in 2018 to US$28.7 billion in 2021.

Value addition

High value-added technical products such as wide-width digital printing substrates, carbon fabrics for high-performance composites, filter media, flame retardant barrier fabrics and heavy-duty membranes are now being coated on Monforts texCoat ranges and finished with the company’s industry-leading Montex stenters.

“Since we acquired the technology that our coating units are based on in 2015, we have made a lot of refinements,” says Hans. “All of these developments are reflected in higher coating accuracy and the resulting quality of the treated fabrics. At the same time, our latest multi-functional coating heads offer an unprecedented range of options, with a wide range of modules available.”

The texCoat user interface is now equipped with the unique Monforts visualisation system and the magnetic doctor blade has greater power reserves. Options include a carbon fibre-reinforced composite coating drum with a more scratch-resistant surface and maximum rigidity and remote control which simplifies exact adjustment for the operator.

Montex stenters in special executions are meanwhile ideal for the drying and finishing of both technical woven fabrics and nonwovens and characterised by high stretching devices in both length and width.

“The European-built Montex range of stenters has earned its leading position in the technical textiles market due to the overall robustness, reliability and economy of these machines,” Hans concludes. “Whatever the intended end-product – and we continue to discover potentially new areas in which technical textiles can be utilised all the time – we have the machine specification and know-how to turn ideas into reality. In India we also benefit from the strong sales and service support of A.T.E. Enterprises.”

Texchtextil India takes place alongside World of Composites at the Bombay Exhibition Centre in Mumbai from November 20-22.

Hexcel Corporation has been approved by Boeing to produce HexPEKK™-100 aerospace structures for major commercial aircraft platforms.

After rigorous review of Hexcel’s proprietary poly-ether-ketone-ketone and carbon fiber material formulation, Hexcel’s superior HexPEKK™-100 end-use components – as well as its highly-controlled HexAM™ additive manufacturing process (which uses selective laser sintering) – are now obtainable through Boeing’s Qualified Provider List (QPL). These HexPEKK™ components will be manufactured-to-print for commercial aerospace applications where complexity, weight reduction, and strong mechanical performance are critical.

Hexcel provides high-rate serial part production with reduced lead-time and at a lower cost than traditional intricately machined aluminum or composite structures. HexPEKK™-100 parts meet interior aircraft smoke and toxicity requirements and are ideal for complex components such as optimized brackets, environmental control system ducts, and castings.

STAMFORD, Conn. – At this year's Paris Airshow [Le Bourget, June 17-23] Hexcel will promote a range of carbon fibers and composite materials used to manufacture high-performance weight-saving structures in civil aircraft, engines, helicopters, and space applications.

Visitors to the Hexcel stand will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® carbon fiber reinforcements. HiTape® dry carbon reinforcements were developed for the automated lay-up of preforms and to complement a new generation of HiFlow™ resin systems, producing high-quality aerospace structures using the resin infusion process. The reinforcements incorporate a toughening veil to enhance mechanical properties and meet the structural requirements for aerospace parts. The I-Beam was manufactured using C-RTM (Compression Resin Transfer Molding) and was injected with Hexcel’s RTM6 resin in a process taking less than five minutes.

Hexcel honeycomb saves weight and enhances stiffness in composite structures, and the company provides a range of engineered core solutions that enable highly contoured parts with precision profiling to be produced to exact customer specifications. A sample part made from aluminum FlexCore® that is CNC machined on both sides and formed and stabilized with both peel ply and flyaway layers of stabilization will be on display.

Another honeycomb innovation is Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb that significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core or can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees Of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.
Another Hexcel technology to benefit aircraft engines is HexShield™ honeycomb which provides high-temperature resistance in nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential reuse of material after a fire.

With 50 years of experience behind its comprehensive range of high-strength, high-strain PAN-based carbon fibers, Hexcel continues to innovate and is introducing two new fibers to its portfolio. HexTow® HM50 combines high modulus and high tensile strength, making it ideal for commercial and defense aircraft and engines. HexTow® 85 was developed specifically to replace rayon-based carbon fiber for ablative applications.

Another area of expertise that uses HexTow® carbon fiber is additive manufacturing, where Hexcel uses PEKK ultrahigh performance polymers and HexAM™ technology to manufacture carbon reinforced 3D printed parts. This innovative process provides a weight-saving solution for intricate parts in highly demanding aerospace, satellite and defense applications. HexPEKK™ structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts with a new technology.

Later this year Hexcel will open a joint research and development laboratory in Les Avenières (Isère), France with Arkema to develop carbon fiber-reinforced thermoplastic prepreg tapes for aerospace, space and defense applications. A spool of thermoplastic prepreg tape will be on display on Hexcel’s stand to showcase this cost-effective technology that enables lightweight parts to be produced in faster production cycles for future generations of aircraft.

Hexcel’s stand is located next to Hexcel’s official distributor for aerospace products, Groupe Gazechim Composites. In 2018, Hexcel and Gazechim formed a joint venture, HexCut Services, to provide aerospace and defense customers with customized kitting services that include Hexcel’s innovative carbon fiber prepreg, fabrics and adhesives. Pre-cut kits save customers time and investment, reduce inventory and minimize material losses through scrap reduction.

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.
