From the Sector

• Technology, creativity and sustainability
• Recycled materials, bright colours, eclectic shapes: excellence is in the details, and the new creations by the Italian-Swiss group have plenty to say.

Mendrisio – Looking at the new Fall-Winter 2021-2022 collection of the Riri Group, it almost seems as if the difficult months to which the pandemic has forced the whole world, have been another new – though unwanted – challenge for the Italian-Swiss company. A testbed that sparked the mind and lit the fire of creativity. Therefore, today, the brand ingredient which for over 80 years has embellished the
garments designed by major fashion system brands with top-quality zips and buttons, also introduces a wide range of heterogeneous creations, intended to cover different aesthetic and functional requirements on the market.

This collection has been divided into three macro-topics; it is a new chapter in the history of the Group.

LIFE SERVING
Keyword: sustainability. Or, more romantically, “Reuse with love”. From the use of materials produced using organic waste and recycled plastics to actual destocking – the re-introduction on the market of unsold items to give them new life through a restyled shape: the topic of “life serving”, for Riri, translates into the meticulous and constant search for materials with a low environmental impact and in the committed attempt to reduce the use of plastic to a minimum. This is why the Group has decided to use recycled polyester tapes, made with new organic cotton, pullers coated with cork, created using 100% recycled plastics or rubber taken from the sole of shoes. Stainless steel – an exceptionally resistant and sturdy material, as well being subject to no galvanic treatments and highly recyclable – characterizes chains and pullers, while the Nylon zip consists of fully recycled tape and chain, and Decor introduces a new 100% polyamide version. On the button side, “life serving” includes buttons with a cork coating, the Zero button with coating made of recycled Meryl polyamide and the F4 with a 100% recycled Nylon head and the heads made of APILON 52 (rubber made of 65% vegetable oils and energy from renewable sources) coated with microfiber from the company Alcantara.

ENGINEERING
This is definitely the most rigorous yet progressive section in the collection, drawing on technological innovation and on uncertainties related to the current situation, to play with shapes, colours and materials. Between zips and buttons there is a prevalence of squared and minimal shapes, also on the tapes of the zips through sublimation and digital printing techniques. The leading colour is grey in its variation of hues, where the insertion of coloured tones sometimes stands out. The leading material, on the other hand, is metal.

OVER SHOCK
A creative topic where “exaggeration” is the keyword, a trend whose style and character somehow remind us of Gen-Z, apart from being especially suitable for outdoors. “Over state” uses the hip hop mood and settings of the Nineties, taking them to the extreme, enlarging shapes and focusing on bright and fluorescent colours such as purple, yellow, blue, orange or green. An example of this is Storm Evo, a zip which is popular in the outdoor sector for its high levels of water resistance and strength, which features a new electric blue chain and tape with reflecting side strips. Also outstanding in terms of originality is the new purple puller, with its anti-theft shape, fixed onto a fluorescent yellow chain. The perfect expression of this category are zippers such as Decor, Nylon and Aquazip, especially recommended for the outdoor sector in general.

COLLECTION HIGHLIGHTS: RESTYLING AND INNOVATION
All the macro-categories selected for the FW 21-22 seasons are included in some special product innovations, most notably the even more minimal and thin shapes of some buttons and the introduction of five different colours for the small synthetic ring, a real point of strength in Cobrax pressure buttons. Also the range of magnetic buttons is complemented by the addition of two extra snaps. As regards zips, the Riri Group team has been working on careful restyling of shapes, more specifically in the shapes of Decor zip bodies – ideal for the luggage industry – further improved from both an aesthetic and functional viewpoint.

STAMFORD – German ultralight aircraft specialist Flight Design has chosen Hexcel as its key supplier adopting low-temperature curing prepreg into its aircraft production. Hexcel’s HexPly® M79 Carbon Fiber prepregs deliver a more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Design and then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype. As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70˚C for eight hours or 80˚C for four hours, reducing tooling costs and increasing build rates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective of laminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components. The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”

Hexcel is collaborating with Madshus, innovator in the world of cross-country skiing, on the engineering of a range ofdry carbon fiber tapes for Madshus’ acclaimed cross-country racing skies. Hexcel’s new HiTape® Dry Carbon Tapes improve the performance, manufacturing efficiency and surface finish of Madshus Skis.

“HiTape® gives us exactly what we need for our automated production processes - consistency and quality. In particular the exceptionally clean edges of the tapes, really makes a difference in our molding process and enhances the surface finish of the finished ski. We always aim for the highest levels of quality and Hexcel HiTape® helps us to deliver that.” concludes Bjørn Ivar Austrem, Technical Director, Madshus.

Hexcel’s new HiTape® Dry Carbon Tapes for Madshus Skis will be on display at ISPO Munich 2020, from 26 to 29 January.

• Ice, style and performance

These are the keywords which describe the new eclectic creations by the Riri Group for the Fall Winter season 2020-2021: a journey through the winter, its atmosphere and its colours Mendrisio, September 2019 - Première Vision Paris (17 - 19 September) will set the stage for the new proposals for the Fall Winter 2020-21 collection by the Riri Group, a leading brand in the zip and button manufacturing sector for high couture and outdoor apparel. A preview of the new collection by the Swiss group will take place at Munich Fabric Start (3 – 5 September).

COLOURS, MATERIALS AND TEXTURES

Winter landscapes and polar tones have inspired the colours of this new collection: nuances of grey, azure and white remind us of the typical tones of ice; also dominant is the presence of blue, intense and rich in contrast thanks to the attractive green inserts; black interventions are then harmoniously inserted as part of the colour palette, creating an appealing interplay of colour references. Tapes, pullers and chains provide new pleasant tactile sensations and unexpected visual inputs, through the search for always new processing methods the iceberg effect reproduced with a laser system, the texture reminding us of snake skin, from marble effect to horn processing, and freehand diamond turning, as well as the three-dimensional drop varnishing and the stylish mother-of-pearl effect.

NOVELTIES

The guiding thread for the new “Winterstorm” collection is the use of nuanced colours and ‘ice-like’ effects, reminding us of winter landscape and climates, as in the new Decor Cristal zip with transparent chain or in the Aquatyre zip, available also in a new luminescent version. Among the new creations, the Metal 3H zip stands out: the smallest and most innovative in the collection, lightweight and with a streamlined design. The provocations for this fall-winter have reached extreme levels, with a zip made of synthetic fur and incorporated buttons, whose cover can be removed and then reapplied, to face polar temperatures with a touch of glamour. Alongside the most fashionable novelties, the research by the Riri group does not cease to surprise in the outdoor sector also as regards buttons. This is confirmed by Rislide, the snap closure with a nylon body and Zama button. The innovative b-lock pressure button – with high lateral hold – has been restyled with a silicone shaped head in three colours. As part of a collection characterised by style and performance elements, it is definitely worth mentioning Zero, also in its invisible version: this button – thanks to its elegant design, combines practicality and style without compromising on performance.

Hexcel, Arkema and their partners are pleased to announce that their joint collaborative project “HAICoPAS” has received approval from Bpifrance and the support (grant of 6 million euros) of France’s Investissements d’Avenir program.

HAICoPAS project is a collaborative project with a total amount of 13.5 million euros lead by Hexcel and Arkema and their industrial partners (Ingecal, Coriolis Composites, Pinette Emidecau Industries (PEI) et l'Institut de Soudure), and academia lead by CNRS (PIMM (CNRS - Arts et Métiers ParisTech - le Cnam), LTEN (CNRS - Université de Nantes). This project follows last year’s announcement of the strategic partnership between Hexcel and Arkema to develop high performance PEKK/carbon fiber UD tapes targeting composite parts for primary aerospace structures.

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.

Hexcel and Arkema have announced that they will open a joint research and development laboratory in Les Avenières (Isère), France in April.

This follows the companies’ previous announcement in March 2018 that they were forming a strategic alliance to develop thermoplastic composite solutions for the aerospace sector, combining the expertise of Hexcel in carbon fiber and Arkema in PEKK.

The companies’ objective at this new lab is to develop carbon fiber-reinforced thermoplastic prepreg tapes to enable lightweight parts to be produced for future generations of aircraft. These solutions will provide lightweight and cost effective technologies including faster production cycles for customers in the aerospace and the space and defense sectors.

Thanks to Hexcel and Arkema’s close collaboration, an initial industrial pilot line will be installed in the new lab in the coming weeks. The companies expect to start supplying carbon/thermoplastic UD tapes from this pilot line to customers for evaluation beginning in Q3 2019.

C-PLY^TM,
THE CHOMARAT REINFORCEMENT THAT HAS ALREADY PROVEN ITS WORTH IN THE AEROSPACE INDUSTRY
CHOMARAT has already made a name for itself in the aerospace market with fabrics, tapes and multiaxial carbon reinforcements, particularly its C-PLY™ range. These materials are designed for primary and secondary structures as well as aircraft interior parts. These highly modular materials offer great angle and ply flexibility and open up new opportunities for designing lighter, more efficient and lower cost composite parts. This is a huge advantage in a market with high productivity demands.
This is why C-PLY™ was recently chosen by VX AEROSPACE for their foldaway drone, which can be stowed inside a cylindrical container and deployed from a tactical aircraft. The carbon multiaxial material is used in the construction of the wing, the horizontal stabilizers, the vertical fin and all of the control surfaces. “There is no better material! The extremely thin multiaxial reinforcement is perfect, because strength and stiffness are tailored according to demand. It offers extremely high performance at a reduced cost.” said VX AEROSPACE Chief Engineer Bob SKILLEN.
