Asphalt Business Unit setzt neue Maßstäbe
Das bewährte HaTelit Produktportfolio und mehr als vierzig Jahre Erfahrung in der Entwicklung und Anwendung von Asphalteinlagen werden jetzt gebündelt in einem einzigen, speziell qualifizierten Kompetenzteam. Die neue Asphalt Business Unit der HUESKER Gruppe rund um Diplom-Ingenieur Andreas Elsing, wird sich ab sofort verstärkt um den nachhaltigen Bau und die Sanierung von Straßen durch die Verwendung von Geokunststoffen einsetzen.

Das Team wird komplettiert durch Experten und Ingenieure wie Fabiana Leite-Gembus, Michael Eßling, Daniel Hilpert und Erhard Luce, die jeweils über mehrjährige Erfahrungen im Straßen- und Verkehrswegebau verfügen.

Ihr Ziel ist es die verantwortlichen Auftraggeber, Planer und Bauunternehmer, aber auch Politiker und die Öffentlichkeit von der hohen Wirtschaftlichkeit und Nachhaltigkeit des Einbaus geotextiler Asphaltbewehrungen bei Neubau und Sanierung von Straßen zu überzeugen. Studien belegen schon lange die vielen Vorteile im Vergleich zur konventionellen Straßenbauweise: bis zu 4-fache Verzögerung von Reflexionsrissbildung, Verlängerung der Nutzungsdauer und des Sanierungsintervalls, Reduktion der Instandhaltungskosten. Dies bedeutet vor allem auch weniger Staus und Verkehrsbehinderungen nebst aller unangenehmen Begleiterscheinungen. Neben der Zeit- und Kostenersparnis zeichnen sich die  Asphaltbewehrungen von HUESKER besonders durch einfache und sichere Verlegung, hohe Widerstandsfähigkeit gegen Einbaubeschädigungen und besonders gute Verbundeigenschaften aus.

Vielzählige Infrastrukturprojekte außerhalb Deutschlands gehen mit gutem Beispiel voran. Im Sinne einer langfristig ökonomischen, ökologischen und ressourcensparenden Lösung, führt heute kein Weg mehr an der Infragestellung des konventionellen Straßenbaus vorbei.

Revolutionizing textile finishing by enhancing sustainability and total process control

Baldwin Technology Company Inc., a member of TMAS, the Swedish textile machinery association, is pleased to announce the launch of the TexCoat G4 at the ITMA trade show in Barcelona from June 20-26, 2019. The TexCoat G4 is the next generation of the company’s revolutionary non-contact precision application system for fabric finishing.

The system enables a continuously high quality and productive textile finishing process with zero chemistry waste and drastically reduced water and energy consumption. TexCoat G4 will be demonstrated by Baldwin in Hall H2, stand A204.

“We are immensely proud to launch the TexCoat G4 at ITMA 2019,” said Eric Norling, Vice President Precision Application Segment, Baldwin Technology. “This is an opportunity to experience an innovation that drastically improves both the process and product quality, while saving time, valuable resources and contributing to a sustainable future.”

The non-contact spray technology brings numerous advantages compared to conventional methods of applying finishing chemistry. The chemistry is uniformly distributed across the textile surface and is applied only where it is required – on one or both sides of the fabric. This is highly beneficial e.g. when applying water repellants on laminated fabrics, as it eliminates the problem of chemistry affecting the quality of the adhesion layer. Furthermore, the non-contact technology eliminates chemistry dilution in wet-on-wet processes, allowing full control of maintaining consistent chemistry coverage rates. Additionally, with no bath contamination during the finishing process, there is zero downtime during colour or fabric changeovers.

Im Projekt futureTEX forschen Industrieunternehmen, wissenschaftliche Einrichtungen und Verbände in einem interdisziplinären Kompetenznetzwerk, um die traditionsreiche Textilbranche in Deutschland fit für die Zukunft zu machen. Bis 2021 arbeiten die rund 300 Akteure an der Entwicklung wesentlicher Bausteine eines Zukunftsmodells.

In den vergangenen Monaten wurden dazu mehrere Forschungsvorhaben abgeschlossen. Unter anderem entwickelten die Partner in den Vorhabenkonsortien Leichtbauteile aus Hanfbastrinde oder photovoltaisch wirksame Schichten auf Technischen Textilien.

Parallel dazu starteten drei weitere Umsetzungsvorhaben, die unterschiedliche Aspekte des textilen Spektrums abdecken. Im F&E-Vorhaben digiTEX-PRO arbeiten die Partner an einer digitalen, textilen Prozesskette zur nasschemischen Funktionalisierung von textilen Flächengebilden. Das Ziel ist eine digital ansteuerbare flexible Ausrüstungstechnologie auf Basis von digitalen Verfahren aus der Druck- und Beschichtungsindustrie für die effiziente vollflächige und geometriegesteuerte Ausrüstung von textilen Flächen.

Beim Vorhaben iTEXFer steht die Entwicklung von vernetzten Fertigungssystemen und Wertschöpfungsstufen im Rahmen des Fabriklebenszyklus im Fokus. Als Ergebnis soll ein textilspezifischer, erweiterbarer Industrie 4.0-Baukasten entstehen, der neben Software und Methoden auch mechanisch-elektronischen Komponenten enthält. Damit sollen zukünftig Entwicklungszeit, Produktionsdurchlaufzeit, Ausfallzeit und die Ressourcennutzung optimiert werden.

Das Vorhabenkonsortium von T-EXoSuit plant die Entwicklung eines textilbasierten Exoskeletts mit individuell einstellbarem graduellen Bewegungswiderstand und User Interface zur präventiven und rehabilitativen Unterstützung des Bewegungsapparats. Mit der Orthese sollen Fehlhaltungen und Überlastungen durch ein individuelles angepasstes textiles Exoskelett reduziert werden. Gleichzeitig können mittels der integrierten Sensorik relevante Bewegungsdaten erfasst und analysiert werden.

Neu ist ebenfalls das futureTEX-Vorhaben „Von der Forschung in die Praxis - futureTEX Inkubator für technische Textilien und disruptive Produkte“. Das Vorhaben wird im Mai starten und als wichtiger Impulsgeber für den Transfer ausgewählter Vorhabenergebnisse in die Wirtschaft fungieren. Bis 2021 sollen nachhaltige Strukturen entwickelt werden, die futureTEX-Inhalte ganz gezielt zur Marktreife bringen. Gleichzeitig soll damit eine Innovationsplattform für die gesamte Branche etabliert werden, die ausdrücklich KMU einbindet sowie Lern- und Anwendungsmodule aufzeigt.

Am 11. April 2019 öffneten die 9 Partnerinstitute des AZL die Türen ihrer Maschinenhallen und Forschungslabore, um vor Ort umfassende Einblicke in ihre Forschungs- und Entwicklungskapazitäten im Bereich Leichtbau-Produktion und Verbundwerkstoffen auf dem RWTH Aachen Campus zu bieten. Als besonderes Highlight dieses Jahr präsentierte das AZL die selbstoptimierende Prozesskette "i-Composite 4.0": Fasersprühen - Trockenfaserplatzierung - adaptives RTM sowie AZL´s neue Proto-typ-Maschinenentwicklung "Ultra-Fast Consolidator Machine" für die hochproduktive und flexible Verarbeitung von thermoplastischen Bändern mit In-situ-Konsolidierung (Gewinner des JEC World Innovation Award 2019).

Mehr als 100 Teilnehmer aus externen Unternehmen sowie aus dem AZL-Netzwerk hatten die Möglichkeit, sich über die neuesten Technologien und Ausrüstungen der Leichtbau-Produktion zu informieren, die nutz-bringende Infrastruktur auf dem Campus kennenzulernen und sich mit international vertretenen Unterneh-men der gesamten Leichtbau-Wertschöpfungskette zu vernetzen, indem sie an fünf Führungen zu den Leichtbauminstituten teilnahmen.

Das AZL bündelte Inhalte im Bereich Textilien (ITA), Kunststoff- und Verbundstoffmaterialien (IKV), Produk-tionstechnologie (WZL, IPT, ILT und ISF), Qualitätssicherung und Produktions-integrierte Messtechnologie (WZL), Leichtbau-Design (SLA), Automobilproduktion (IKA) sowie Multi-Material-Systeme und Prozessin-tegration (AZL).

Einmal im Jahr bietet das AZL durch den Open Day einen exklusiven und in der Breite einmaligen Einblick in die F&E-Kapazitäten der Institute im Bereich Leichtbau und Composite Technologien auf dem Campus der RWTH Aachen. In fußläufiger Entfernung arbeiten auf einer der größten Forschungslandschaften Euro-pas Forscher und Studenten aus 9 Instituten an neuesten Technologien zur kosteneffizienten Entwicklung und Produktion von Leichtbauteilen. Die Forschung unter enger Einbeziehung von Industrieunternehmen deckt die gesamte Wertschöpfungskette von der Faserherstellung über die Werkstoff- und Verarbeitungs-technik bis zur Qualitätssicherung und die Komponentenerprobung ab.

In unterschiedlichen Ausführungen, von Papier bis zu dickem Filz, dient das Material als Brandschutz in elektronischen Geräten, Sitzpolstern und anderen Anwendungen. GULFENG gibt es als dünnes Papier, gewebt, oder gefilzt.
 
Vom 14. bis 17. Mai 2019 präsentiert der japanische Materialtechnologie-Riese Toray die Funktionstextilien des Unternehmens auf der Techtextil in Frankfurt. Ein Highlight ist dabei das neue Flammschutzgewebe GULFENG, das hervorragende flammhemmende Eigenschaften besitzt und als Flammenbarriere dient. Das Gewebe ist in verschiedenen Ausführungen erhältlich und somit für ein breites Anwendungsspektrum geeignet.

Im Vergleich zu anderen flammhemmenden Materialien, die aus Glasfaser-, m- und p-Aramid- oder Ox-PAN-Filz bestehen, ist GULFENG leichter, dünner und flexibler. Die Papiervariante ist 0,06 mm dick und wiegt 60 g/m² – sie sieht wie normales Papier aus und fühlt sich auch so an. Zusätzlich kann das Material zu einem weichen Stoff gestrickt oder gewoben und zu biegsamen Matten gefilzt werden. Durch diese Vielfalt eigenet sich GULFENG für Batterien ebenso wie für Bettwäsche oder Bussitze.

Trotz der geringen Dicke büßt GULFENG seine flammhemmenden Eigenschaften nicht ein und dient als Flammenbarriere. Ein Feuer kann sich nicht ausbreiten oder umliegende brennbare Materialien entzündet. Um dies zu erreichen kombiniert Toray thermoplastisches Polyphenylensulfid (PPS) mit oxidierten Polyacrylnitrilfasern (OX-PAN). Erwärmt eine Flamme das Material auf 285°C, beginnen die PPS-Fasern zu schmelzen und bilden eine dünne Membran um die Ox-PAN-Fasern. Diese absorbieren Wärme und oxidieren, wodurch eine vollständig geschlossene Barriere gegen die Flammen entsteht. In Flugzeugen und Zügen wird GULFENG als Fammenbarriere in Sitzkissen verwendet.

Techtextil 2019: Schoeller launches its new finishing technology called NanoSphere® Plus. The special effect of this new development is its protection against fingerprints and greasy stains. Furthermore, even after being absorbed by the fabric stains are quickly and easily wiped away without washing.

Every human being leaves its marks. In particular, on daily-use items that are picked up or touched often. Especially on textile surfaces, hand and fingerprints in combination with dirt and dust particles leave an unpleasant, greasy dirt film, which is very difficult to clean.

NanoSphere® Plus, developed by Schoeller Technologies AG, the business unit for technologies at Schoeller Textil AG, works on the basis of a functional chain. Textiles are equipped with a matrix finish to reduce the capillary effect in the textile’s fibers. Especially unpleasant sebum residues and dirt that are often released by finger and handprints are less absorbed by the fabric and can be easily wiped away.

Beside the excellent protection against finger and handprints, textiles with NanoSphere® Plus are additionally water and oil repellent, abrasion resistant and extremely durable. The finishing technology rarely affects the look or feel of the fabric.

Non-washable textiles that are often touched by hands or fingers, or fabrics that are in direct contact with the skin benefit most from this new technology. Therefore, NanoSphere® Plus is ideal for woven fabrics and synthetic leather or synthetic suede for bags, covers of electronical devices, head phones, loud speakers or other items in the field of interior equipment.

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.

• Hexcel’s Composite Innovations For Aerospace, Automotive, Energy And Marine Applications At JEC World 2019 Hall 5 - Stand J41

STAMFORD, Conn. – At this year’s JEC World taking place in Paris on March 12-14, Hexcel will promote a wide range of composite innovations for customer applications in aerospace, automotive, energy and marine markets.

Aerospace Innovations

Hexcel’s HiTape® and HiMax™ dry carbon reinforcements were developed to complement a new generation of HiFlow™ resin systems, producing high quality aerospace structures using the resin infusion process. HiTape® was developed for the automated lay-up of preforms and HiMax™ is a range of optimized non-crimp fabrics (NCF). Both products incorporate a toughening veil to enhance mechanical properties, meeting the structural requirements for aerospace parts.

Visitors to JEC will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® reinforcements, and an Opticoms rib made with HiMax™ NCF. The Opticoms rib and I Beam were both manufactured using C-RTM (Compression Resin Transfer Molding). They were injected with Hexcel’s RTM6 resin in a process taking less than 5 minutes. The total manufacturing cycle for both parts was just 4.5 hours.

Also among the Aerospace exhibits, Hexcel will display a composite petal for a satellite antenna, manufactured by Thales Alenia Space Italia. The petal is part of a set of 24 deployable structural elements that form the large area reflector assembly used on board Low Earth Orbit (LEO) observation satellites. Thales Alenia Space Italia selected Hexcel’s HexPly® M18 prepreg for this application, acknowledging the superior mechanical and outgassing properties provided.

Another Hexcel prepreg application on show is a “zero” frame, manufactured by Aerofonctions for the engine area of Daher’s TBM 910/930 single-engine turboprop aircraft. Hexcel’s HexPly® M56 prepreg was selected by Daher for the “zero” frame – a product developed for Out of Autoclave applications that provides the same high quality and performance as autoclave-cured prepregs, from a simple vacuum bag cure in an oven.

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.

HexTow® carbon fiber holds the most qualified carbon fiber positions on aerospace programs in the industry and is the best unsized fiber available on the market. It provides excellent bonding interfacial properties with thermoplastic matrices and is the best-performing fiber for 3D printing applications.

Additive manufacturing is another area of expertise for Hexcel, using PEKK ultra-high 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.

Hexcel is well known for its range of weight-saving, stiffness-enhancing honeycombs and the company adds value by providing a range of engineered core solutions to customers from facilities in the USA, Belgium and the newly opened Casablanca plant in Morocco. Hexcel’s engineered core capabilities enable highly contoured parts with precision profiling to be produced to exacting customer specifications. An example of such a part will be on display at JEC. Made from Aluminum FlexCore®, the part is CNC machined on both sides, and formed and stabilized with both peel ply and flyaway layers of stabilization. Aircraft engines benefit from a number of Hexcel core technologies 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.

Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb 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.

HexBond™ – the new name in Adhesives

Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil. The company has now decided to unite the range by marketing all of its adhesive products using HexBond™ branding. The comprehensive range of HexBond™ structural film adhesives, foaming adhesive films, paste adhesives, liquid shims, epoxy fillets and Chromium free liquid primers is suitable for a wide range of applications in combination with Hexcel’s prepreg and honeycomb products.

Automotive Innovations

Hexcel’s carbon prepreg patch technology provides an innovative way of locally stiffening and reinforcing metal parts, providing noise and vibration management functionality. HexPly® prepreg patches consist of unidirectional carbon fiber impregnated with a fast curing epoxy matrix that has self-adhesive properties, enabling it to bond to metal in a highly efficient one-step process. These key technology properties are demonstrated in an 18.5kg aluminum subframe (that is 50% lighter than steel equivalents), which was reinforced with 500 grams of HexPly® prepreg and tested by Saint Jean Industries. The part demonstrates a significant reduction in noise, vibration and harshness (NVH). Other benefits include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. With this technology Hexcel is a finalist in the JEC Innovation Awards 2019 in the Automotive Applications category.

HexPly® prepreg patch technology was also applied to a hybrid side sill demonstrator developed with Volkswagen and Dresden University to address future crash test requirements, specifically for electric cars. Combining fiber-reinforced plastic (FRP) with metal, the hybrid construction allows for optimum performance including weight savings, enhanced safety, increased energy absorption, battery protection in a crash situation and production flexibility.

Hexcel will also display a lightweight CFRP transmission crossmember produced from Hexcel’s high performance HexMC®-i 2000 molding compound. The transmission crossmember was developed in partnership with the Institute of Polymer Product Engineering (at Linz University), Engel and Alpex. As the part connects the chassis together and supports transmission it has to be stiff and strong, resisting fatigue and corrosion. Hexcel’s HexMC®-i 2000 was selected as the best-performing molding compound on the market, curing in as little as two minutes to produce lightweight, strong and stiff parts.
To produce the transmission crossmember HexMC®-i 2000 preforms are laid up in Alpex molds and compression-molded in a v-duo press that was tailored for the application by Engel. Ribs, aluminum inserts and other functions can be molded into the part using the single-stage process, reducing component-count. Any offcuts from the preforms can be interleaved between the plies of material to provide additional reinforcement in key areas - meaning that the process generates no waste.

Other Automotive promotions on Hexcel’s stand at JEC World include a composite leaf spring manufactured by ZF using HexPly® M901 prepreg. In contrast to steel leaf springs, composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. HexPly® M901 prepreg reduces the cure cycle to below 15 minutes and 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.

Marine Innovations

Hexcel has a comprehensive range of products aimed at racing yacht and luxury boat builders that include America’s Cup, IMOCA class and DNV GL-approved prepregs, woven reinforcements and multiaxial fabrics for hull and deck structures, masts and appendages.

At JEC World Hexcel will display an IMOCA yacht mast manufactured by Lorima using HexPly® high modulus and high strength carbon fiber prepreg from Hexcel Vert-Le-Petit. Lorima is the exclusive official supplier of masts for IMOCA 60 class racing boats.

Hexcel’s HexTow® IM8 carbon fiber has been selected as the highest performing industrial carbon fiber on the market and will be used by spar and rigging manufacturer Future Fibres to manufacture their AEROrazr solid carbon rigging for all the teams in the 36th America’s Cup.

Hexcel’s HiMax™ DPA (Dot Pattern Adhesive) reinforcements are non-crimp fabrics supplied pre-tacked, allowing multiple fabrics to be laid-up more easily in preparation for resin infusion. Providing an optimal, consistent level of adhesion, they allow a faster and more consistent resin flow, as well as eliminating the use of spray adhesive for a healthier working environment and lower risk of contamination. Simply unrolled and applied to the mold or core layer before the introduction of resin, HiMax™ DPA fabrics are widely used in boat building, where lay-up times can be reduced by up to 50%.

Wind Energy Innovations

Hexcel has developed a range of HexPly® surface finishing prepregs and semi-pregs for wind turbine blades and marine applications. Providing a tough, durable and ready-to-paint surface without using in-mold coats, these products shorten the manufacturing cycle and reduce material costs. HexPly® XF2(P) prepreg is optimized for wind blades and has a ready-to-paint surface, straight from the mold, saving at least 2 hours of takt time.

Polyspeed® pultruded carbon laminates were developed for load-carrying elements in a blade structure and are manufactured with a polyurethane matrix that provides outstanding mechanical performance in terms of stiffness and durability. The blade manufacturing process is optimized, with increased throughput. The pultruded laminates are supplied in coils as continuous cross section profiles.
HiMax™ non-crimp fabrics using E-glass, high modulus glass and carbon fibers are also available in a wide range of unidirectional, biaxial and triaxial constructions. HiMax™ fabrics have applications throughout the turbine, from the stitched carbon fiber UDs used in the main structural elements, to glass fabrics and hybrids for blade shells and nacelles. There are also specialist applications such as lightweight fabrics for heated leading edge de-icing zones.
