On April 11^th, 2019, the 9 Partner Institutes of the AZL opened the doors of their machinery halls and research labs to provide an extensive and on-site insight into the research and development capaci-ties in the field of lightweight production and composites at the RWTH Aachen Campus. As a special highlight of this year, the AZL presented the "iComposite 4.0" self-optimizing process chain: fiber-spraying - dry fiber placement - adaptive RTM as well as AZL´s new prototype machine development "Ultra-Fast Consolidator Machine" for highly productive and flexible processing of thermoplastic tapes with in-situ consolidation (winner of the JEC World Innovation Award 2019).

More than 100 Participants from external companies as well as from the AZL Network had the possibility to experience updates on the latest lightweight production technologies and equipment, get to know the bene-fital infrastructure on the Campus and network with internationally represented companies of the entire light-weight value chain researches by taking part in five guided tours to the lightweight institutes.

The AZL brought together content in the field of textiles (ITA), plastics and composite materials (IKV), pro-duction technology (WZL, IPT, ILT, and ISF), quality assurance and production-integrated measurement technology (WZL), lightweight design (SLA), automotive production (IKA) as well as multi-material systems and process integration (AZL).

Once a year at the Open Day, the AZL offers an exclusive and widespread unique insight into the R&D capacities of the institutes in the field of lightweight and composite technologies on the campus of RWTH Aachen University. Within walking distance, researchers and students from 9 institutes are working on the latest technologies for the cost-efficient development and production of lightweight components within one of the largest research landscapes in Europe. The research, closely involving industrial companies, covers the entire value chain from fiber production, materials and processing technology to quality assurance and com-ponent testing.

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.

Das ITM wird den Besuchern der JEC einen umfassenden Einblick in die aktuellen Arbeiten auf dem Gebiet der Maschinen- und Produktentwicklungen entlang der gesamten textilen Prozesskette geben.
Ein Highlight auf der JEC 2018 ist die Präsentation der vielfältigen Möglichkeiten, die die Struktur- und Prozesssimulation textiler Hochleistungswerkstoffe und textiler Fertigungsprozesse bietet.

Mittels skalenübergreifender Modellierung und Simulation wird am ITM ein tiefgreifendes Material- und Prozessverständnis erreicht. Dazu wurden Finite-Element-Modelle auf der Mikro-, Meso- und Makroskala entwickelt und validiert. Beispiele aus aktuellen Forschungsprojekten des ITM demonstrieren die vielseitigen Möglichkeiten und Einsatzbereiche der modernen Simulationsmethoden auf dem Gebiet der Textilmaschinen.

Weiterhin werden beispielhafte innovative konstruktive Highlights aus dem Bereich der Flachstricktechnologie durch das ITM vorgestellt. Eine besondere Herausforderung bei der Verwendung von Faserkunststoffverbunden (FKV) mit komplexen Freiformflächen ist neben der belastungsgerechten Auslegung eine wirtschaftliche und produktive Fertigung, wofür am ITM innovative, hochdrapierbare und anforderungsgerechte textile Halbzeuge entwickelt werden. Konstruktive Neu- und Weiterentwicklungen im Bereich Textilmaschinen erfolgen dabei in enger Zusammenarbeit mit namenhaften Textilmaschinenherstellern, wie u.a. Stoll, Steiger und Shima Seiki.  

Im Rahmen einer Projektbearbeitung konnte am ITM ein innovatives Verfahren für die kontinuierliche und damit hochproduktive Fertigung von komplexen, schalenförmigen und hohlprofilförmigen 3D-Preforms aus Hochleistungsfaserstoffen entwickelt und erfolgreich umgesetzt werden. Durch die prozessintegrierte Strukturfixierung eignen sich die Preforms hervorragend für die Weiterverarbeitung zu FKV-Bauteilen. Hierbei arbeitet das neue Umformverfahren ohne aufwändige, bewegte bzw. aktiv angetriebene Elemente. Daher ist die Ausformung komplexer Geometrien bei engen Bauraumsituationen besonders gut zu realisieren. Damit gelingt erstmals die kontinuierliche und reproduzierbare Herstellung geschlossener hohlprofilförmiger 3D-Preforms mit sehr guter und reproduzierbarer Qualität, die zur JEC ausgestellt werden.

Ein am ITM erfolgreich etablierter Entwicklungsschwerpunkt sind 3D-Strukturen in Form von Near Net Shape Preformen, die zur JEC präsentiert werden. Dazu gehören z.B. ebene und gekrümmte Bauteile mit integrierten Rippen für die Steigerung der Biegesteifigkeit von hoch tragenden Bauteilen, die am ITM kontinuierlich in einem simulationsgestützten Verarbeitungsprozess gefertigt werden. Eine besondere Herausforderung ist die Entwicklung von dringend benötigten anforderungsgerechten Knotenverbindungselementen aus Glas- und Carbon-Filamentgarnen, die mittels hochkomplexer simulationsgestützter Bindungskonstruktionen auf modernsten computergesteuerten Textilmaschinen am ITM hergestellt werden. Für diese Entwicklungen wurde das ITM mehrfach international ausgezeichnet.

Zum Thema Multimaterialcomposites auf Basis von textilen Halbzeugen und Metallblech werden Ergebnisse anhand von Technologiedemonstratoren offeriert, die im Rahmen interdisziplinärer und institutsübergreifender Forschung entlang der gesamten Prozesskette erfolgreich umgesetzt wurden. Im Rahmen mehrerer Forschungsprojekte wurde eine Prozesskette entwickelt, die eine kostengünstige und großserientaugliche Bauteilfertigung von FKV-Metallblech-Verbunden durch in-Situ-Umfom-Fügen aus den Halbzeugen erlaubt.  

Auf der JEC stellt das ITM auch exemplarische Demonstratorstrukturen wie Near Net Shape Preforms und textile Bewehrungen für Carbonbetonanwendungen vor, die mittels der am ITM fest etablierten Multiaxial-Kettenwirktechnologie, gefertigt worden sind. Durch eigene Weiterentwicklungen beim individuellen Kettfadenzulieferungs, -versatz und abzugssystem, bei der Fertigung thermoplastischer Hybridspreizbänder sowie bei dem online-Beschichtungssystem für textile Bewehrungen können maßgeschneiderte Halbzeuge hergestellt und neue Anwendungsfelder erschlossen werden.  

Weiterhin wird am ITM die Entwicklung und Umsetzung von neuartigen Garnkonstruktionen aus recycelten Carbonfasern (rCF) für neue Verbundwerkstoffe erfolgreich vorangetrieben. Mit einer sogenannten Spezialkrempelanlage werden recycelten Fasern aufgelöst, vereinzelt und zu einem breiten gleichmäßigen Band zusammengeführt. Anschließend können daraus auf Basis verschiedener Spinntechnologien neuartige Hybridgarnkonstruktionen aus gleichmäßig vermischten recycelten Carbon- und Thermoplastfasern gefertigt werden. Ausgewählte Garnkonstruktionen und daraus gefertige Demonstratoren werden den Besuchern zur JEC präsentiert.

STAMFORD, February 26, 2018 - at JEC World 2018, taking place in Paris March 6-8, Hexcel will display an array of product innovations for customer applications in aerospace, automotive, wind energy and marine markets.
Hexcel’s banner at the exhibit hall entrance features the Airbus H160 helicopter and A350 XWB aircraft, both with carbon fiber livery to acknowledge the high Hexcel composites content in both programs. Hexcel’s reinforcements, prepregs, adhesives and honeycomb materials were selected for the H160’s composite fuselage structures and main rotor blades, contributing to the lightweight fuel-saving design and performance optimization. Airbus has loaned Hexcel an H160 BLUE EDGE blade to display on the booth.

Among the Aerospace promotions at Hexcel’s booth are carbon-reinforced 3D printed parts, made from Hexcel’s HexAM™ additive manufacturing technology that uses PEKK ultra-high performance polymers. Hexcel acquired this technology from Oxford Performance Materials in December 2017 to provide 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.

Aircraft engines benefit from a number of Hexcel technologies that will be promoted at JEC 2018, including HexShield™ honeycomb that provides high temperature resistance in aircraft engine 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 re-use of material after a fire event.
Another honeycomb innovation from Hexcel is 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. An example of this technology will be on display at JEC 2018.

Rounding off the aircraft engine exhibits is a CTi fan blade for new generation lightweight turbofan engines from Rolls-Royce, manufactured from Hexcel’s HexPly® M91 high toughness and impact-resistant epoxy prepreg. Hexcel supplies HexPly® M91 as slit tape for the automated lay-up of the complex aerodynamic shape, with a constantly changing thickness across the blade length. The blade which is thinner and lighter than titanium fan blades is currently undergoing flight tests.
Hexcel’s HiTape® and HiMax™ dry carbon reinforcements that were developed for the automated lay-up of preforms for resin-infused aerospace structures will be promoted at the show. Two demonstrator parts, one made with HiMax™ and one with HiTape®, were both infused with HexFlow® RTM6 resin to demonstrate the potential benefits of an integrated design for aircraft skins, spars and stiffeners that meets OEM requirements for production rate increases and cost effectiveness.

Hexcel is also introducing its new range of HiFlow™ advanced liquid resins for aerospace structures manufactured by liquid molding technologies. Based on novel proprietary chemistry, the new resin family will enhance the performance of composites and ease processing when combined with HiTape® and HiMax™ dry carbon reinforcements. HiFlow™ HF610 is the first resin in the range.
Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil last October. Hexcel is relaunching the acquired products under the new HexBond™ brand name at JEC World. This fast-growing range of pastes, liquid shim and film adhesives has a wide spectrum of operating temperatures and is in qualification with a large number of aerospace and industrial OEMs.
In the Planet Aerospace area at JEC, Daher and Hexcel will jointly display an aircraft spar manufactured from HexPly® M56 prepreg. Hexcel’s Neil Parker and Daher R&T Director Dominique Bailly will give a joint presentation focusing on the materials used and the benefits for the finished part. The aircraft spar was designed and manufactured by Daher using Hexcel’s HexPly® M56 prepreg, in slit tape format, that was developed for automated deposition and out-of-autoclave curing. The spar was manufactured using only the vacuum bag process and demonstrates very low porosity levels. It is currently undergoing testing and validation through CORAC funding.

Hexcel’s Automotive promotions at JEC World 2018 include a new prepreg for composite leaf springs, HexPly® M901. In contrast to steel leaf springs used for suspension on vans, trucks and SUVs, newer composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. Hexcel’s HexPly® M901 prepreg raises the bar further, reducing mold cure time below 15 minutes, a 50% reduction compared to standard industrial prepregs. HexPly® M901 provides 15% higher mechanical performance, with enhanced fatigue properties. It also operates at high temperatures, providing a Tg of up to 200°C following a post cure. Hexcel’s expertise in manufacturing heavy weight glass UD prepregs, with fiber areal weights of up to 1600gsm, allows the company to offer a highly cost-competitive solution for the rapid manufacture of these safety critical components.

Hexcel is constantly seeking ways to ensure that customers obtain the maximum benefit from composites and has recently acquired state-of-the-art simulation technology that accurately predicts how HiMax™ non-crimp fabrics will drape in a mold. Working in collaboration with Nottingham University Hexcel has created a car seat shell, for which the material selection was optimized using this new drape simulation technology. Visitors to Hexcel’s stand at JEC will see an on-screen demonstration that illustrates how the simulation tool operates, predicting process and performance and ensuring that the optimum fabric architecture is quickly identified, reducing the need for expensive trial programs.
Hexcel’s HexMC®-i 2000 carbon fiber/epoxy molding compound has been successfully used by Audi to manufacture a high-performance engine cross brace. HexMC®-i is a fast curing high-performance molding material, suitable for the series production of complex shaped parts and providing excellent mechanical properties. The Audi cross brace covers the engine, providing torsional stiffness for enhanced drive dynamics.

Hexcel’s product offering for customers in the Marine industry has expanded following the acquisition of Formax in 2016 and Structil in 2017. At JEC World, Hexcel will promote its enhanced portfolio of carbon fibers, prepregs, woven reinforcements and multiaxial fabrics for builders of racing catamarans and luxury yachts.
Marine customers have supplied a number of parts for display to illustrate their expertise in manufacturing composite structures from Hexcel materials. These include part of a Diam 24 yacht mast made by ADH Inotec from Hexcel’s HexPly® M79 fast curing, low temperature cure prepreg. ADH Inotec purchased the prepreg from Composites Distribution, a Hexcel Official Distributor that also supplied HexPly® M9.6 prepreg to Lorima for the Outremer 5X catamaran mast section on display. Part of Lorima’s 42m wing mast for a multihull racing boat made with HexPly® prepreg from Vert-Le-Petit (formerly Structil) will complete the marine display.

Hexcel’s innovations for Wind Energy include Polyspeed® pultruded laminates for load-carrying elements in wind blades. These continuous cross-section profiles, made from a polyurethane matrix reinforced with unidirectional carbon fiber, provide consistently high mechanical properties, including high stiffness, fracture toughness and shear strength, combined with low weight and durability. Visitors to Hexcel’s stand will see a 2m diameter coil of pultruded carbon laminate that contains 255m of material in a single roll. This technology offers an economical way of reinforcing large-scale composite structures such as wind turbine blades. Hexcel will also launch its surface finishing prepreg for wind turbine blades and components. This provides a tough, durable and ready-to-paint blade surface without the use of gel coat and results in faster blade manufacture, saving time in production and reducing material costs. The benefits of the new surfacing prepreg will be demonstrated via a wind blade exhibit that has been given four different treatments across the blade surface. These include a section with gel coat, a section of standard prepreg without gel coat, and a section where a fleece has been added to improve surface quality but still requires preparation before painting due to pin holes. The final section made with new HexPly® XF2P surfacing prepreg has a ready-to-paint surface, straight from the mold, without any requirement for gel coat, fleece or finishing operations.
