From the Sector

Rund 97 Prozent weniger CO2e-Emissionen, 94 Prozent Re-Use Quote – dies sind nur einige der Ergebnisse der am 5. September in Bonn vorgestellten EPEA-Studie zum Re-Use Konzept des ersten Re:Think-Stores des Hamburger Outdoor-Ausrüsters Globetrotter.

Erst vor wenigen Monaten hat Globetrotter seinen ersten Re:Think Store in Bonn eröffnet – einen Laden mit ganz besonderem Konzept: Denn der Retailer hat nahezu die gesamte Einrichtung des Vormieters Conrad Electronic übernommen und im neuen Store kreativ weitergenutzt. Und auch sonst wurden fast ausschließlich gebrauchte Materialien verwendet: So wurden Staubsauger-Halterungen zu Rucksack-Trägern umfunktioniert und alte OSB-Platten und ausrangierte Bleche verwandelten sich in eine Teststrecke für Wanderschuhe. Ein Highlight des Stores stellt eine von einem Künstler geschaf¬fene Bärenskulptur aus Metallschrott dar. Ergänzt wird das Re:Think-Konzept durch nachhaltige Angebote wie eine eigene Reparaturwerkstatt sowie die bis dato größte 2nd Hand Verkaufsfläche in einem Globetrotter-Store.

„Schon bei der ersten Besichtigung des Objektes trieb mich der Gedanke, der Retail und der Ladenbau muss sich ändern. Wir müssen uns ändern. Alles raus und neu, das kann künftig nicht mehr der richtige Ansatz sein,“ erinnert sich Globetrotter Geschäftsführer Andreas Bartmann. CEO Andreas Vogler ergänzt: „Einer der nachhaltigsten Ansätze ist es, Dinge zu nutzen, die bereits da sind. Es erfordert Mut und Pioniergeist, diesen Weg zu gehen. Doch die Ergebnisse der wissenschaftlichen Untersuchung unseres Partners EPEA zeigen, dass es sich lohnt.“

Diese wurden am 5. September im Bonner Store vorgestellt. Keynote-Speaker waren Prof. Michael Braungart, Chemiker und Verfahrenstechniker sowie Miterfinder des Cradle to Cradle-Prinzips und international tätiger Retail-Experte Wolf-Jochen Schulte-Hillen.

Ein konventionelles Ladenbau-Projekt vergleichbarer Größe hätte, so Berechnungen von EPEA, rund 105 Tsd. kg CO2e erzeugt. Durch das Re-Use Konzept des Re:Think Stores wurden nur 3,12 Tsd. kg CO2e emittiert. Die Weiterverwendung bereits vorhandener Materialien trug zu einer CO2e-Vermeidung von 102,23 Tsd. kg, also rund 97 Prozent, bei. Dies entspricht in etwa der Menge an CO2, die entstehen würde, wenn man die Erde rund ein Dutzend Mal mit dem Auto umrunden würde.

Insgesamt kommt der Store auf eine Re-Use Quote von 94 Prozent – d. h. die meisten der verwendeten Materialien und Möbelstücke waren bereits zuvor in Gebrauch, etwa beim Vormieter Conrad Electronic oder in einem Globetrotter Store. Rund 88 % der in der Filiale verbauten Materialien können auch in Zukunft wiederverwendet werden, da sie ohne Beschädigung oder erheblichen Aufwand demontierbar bzw. reparierbar sind: Kreislaufwirtschaft im Ladenbau ist möglich.

Neuer Circularity Passport Interiors
Im Rahmen der Zusammenarbeit mit EPEA entstand die Idee, einen „Circularity Passport Interiors“, kurz CPI, ähnlich dem bereits bestehenden „Circularity Passport Buildings“, zu entwickeln. Dieser dient dazu, die Umsetzung des Cradle-to-Cradle-Designprinzips in Bezug auf die Innenraumgestaltung zu bewerten. Ziel des Designprinzips ist es, Rohstoffe für Produkte, Prozesse und Gebäude so einzusetzen, dass diese entweder in einem technischen Kreislauf in gleicher Qualität erhalten bleiben oder in einen biologischen Kreislauf zurückgeführt und komplett abgebaut werden können.

Each year, since its creation more than 20 years ago, the JEC Composites Innovation Awards celebrate successful projects and cooperation between players of the composites industry. The competition has especially shined a light on some 203 companies and 499 partners, awarding them for the excellence of their composite innovations.

The ceremony took place on April 26th in Paris. Highlighted by the presence of jury members, finalists and winners but most importantly, as it was livestreamed, the gathering of many people all around the world to watch the awaited results.

The enthusiasm for the Innovation Awards, exactly 7 days prior to JEC World, is a good sign of the industry’s eagerness to get back together and ensure the future of composites innovation.

The second C.L.A.S.S. ICON AWARD expands its vision embracing fashion streetwear with an attitude and bets on DUARTE, an emerging label committed to sustainability that shows a new way of being cool, yet responsible. “The C.L.A.S.S. ICON AWARD is much more than prize, it’s an open workshop with influential professionals that will support DUARTE in reaching the next level and being able to share my vision for responsible fashion”, comments Ana Duarte.

The designer (b.1991) launched her label DUARTE in 2016 just after graduation. Since then, the fresh, colourful and power-propelling brand has conquered both catwalks and cities’ streets with a responsible message. “Sustainability means durability, fair work practices, recycled materials and zero-waste,” is Ana’s mantra. Indeed, the collection is the result of a virtuous balance between production and locally-sourced, recyclable high-quality materials harnessed from factories’ deadstock. DUARTE also means circularity, the garments can be re-used and upcycled to create new collections.

The C.L.A.S.S. ICON AWARD is a project led by C.L.A.S.S. with the special support of IDEE BRAND PLATFORM which assists fashion brands in commercial activity, WHITE Milano, international fair supporting the new generations and independent brands with special projects since its inception and responsible shopping platform Renoon. Together they will all support DUARTE for a full year at 360°, from consultancy to communication.

Devan, one of the leading companies in sustainable and functional textile finishes, has been working together with Jeanologia, a global leader in sustainable and efficient finishing technologies for textiles, to reduce further water consumption during the application of Devan’s awarded BI-OME® antimicrobial and R-Vital® skincare range.

With increased attention to climate change and limiting excess water consumption in textile production (whether denim or other textiles), Devan and Jeanologia worked together to evaluate the application of Devan finishes onto garments via the patented e-Flow technology.

e-Flow technology can accomplish a considerable number of finishing effects with the highest quality, a minimal amount of water and zero discharge. The technology uses micronization and nebulization to substitute traditional abrasion process and deliver performance chemistry using nano-bubbles instead of water. It reduces the cost of application, saves the amount of water used and ensures that the correct amount of chemistry stays in the garment and not in the water. e-Flow is the perfect fit for every industrial washing machine. This allows mills and brands to apply Devan’s technologies in a more sustainable way than using traditional application equipment, even for smaller production runs and direct onto garments.

“With the global textile production using 4% of the global freshwater withdrawal, here at Devan we are continuously working on more sustainable solutions”, says Dr. Vanessa Daelman, CTO at Devan. “Next to this, we of course highly value sustainable application methods from Jeanologia, like e-Flow, in order to reduce the excess water usage during textile application. We are delighted that we could work together with Jeanologia and establish that Devan technologies can be easily applied via these technologies onto garments or fabrics like denim and with full retention of functionality. This application method also allows post garment treatment of our finishes, for example an antimicrobial treatment onto already finished garments, which will be increasingly important in a more circular textile world where re-use plays an important role”, Dr. Daelman concludes.

For the cooperation with Lidl within the project “Biodegradable textiles with prints” the CHT Group developed innovative recyclable textile print products.

These Lidl textiles are produced with CHT print pastes and pigments and were certificated by the internationally active consulting institute EPEA GmbH - Part of Drees & Sommer according to the Cradle to Cradle Certified™ Gold Standard. With this pilot project the companies demonstrate their sense of responsibility for people and the environment as well as their commitment in the field of circular economy.

According to the Cradle to Cradle approach, shortly C2C, products shall merge into a biological or technical cycle after the end of their life cycle. This re-use helps prevent waste and save raw materials. The impact on the environment and health of all of the ingredients of C2C textiles is already tested in the design stage and during manufacturing. C2C experts additionally ensure a gapless control of the manufacturing processes. They check the chemicals in use, make sure that the water is kept clean and that renewable energies are used. Since this control affects the complete textile supply chain, it guarantees absolute transparency.

The CHT Group can now offer high quality and sustainable substitutes for common textile print pastes with its first biodegradable print pastes and pigments.

• 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.
