From the Sector

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.

The market for the production of carpet yarn is increasingly evolving towards more demanding processes. However, beyond commodity products, standard plants can no longer fully exploit their advantages. From 20th to 22nd March 2018, Oerlikon Neumag will be presenting an economical alternative in Shanghai in hall W3, booth F03 at the Domotex asia/Chinafloor, the leading floor covering trade fair in the Asia-Pacific region: the BCF plant Sytec One with single-end technology.

If the requirements for the production of BCF yarns increase, for example, from recycled polyester or fine filaments, then this can also lead to higher breakage rates. Highly standardised production plants must then often strike compromises with regard to throughput, quality or cost-efficiency. In such cases, the Sytec One offers a good solution instead of the mostly three-end technology plants for standard processes.

Single-end technology with 98% productivity

This BCF plant works with only one yarn (end) per position, making it ideal for demanding production processes. The reason: when a yarn break occurs only one yarn tears, all other yarns continue to run. This not only simplifies troubleshooting, it also reduces the re-threading time. In addition, less waste is produced. As a result, the productivity of the Sytec One is still over 98% for ten breakages a day, while a plant with three-end technology only reaches around 92%.

Faster processes due to a straight yarn path

In addition, the absolutely straight yarn path of the Sytec One enables significantly higher process speeds of up to 15% in spinning and texturing processes compared to multi-end technologies. Higher total titers of up to 6,000 dtex can also be produced without any problems. The gentle yarn guidance also ensures minimum friction on the individual filaments. This means less yarn breaks and a more stable process.

Optimised key component: spinning pack

Last but not least, the engineers at Oerlikon Neumag have developed a new design for the spinning pack. This central component of every BCF machine significantly influences the yarn quality. The corresponding solution for the Sytec One optimises the polymer flow in the spin pack, thus reducing the polymer dwell time. This leads to shorter product and colour change times and increases the plant efficiency. In addition, the spinning packs were widened so that yarns with up to 500 filaments can now be produced.

The product mix is decisive

In view of these advantages, the single-end Sytec One is recommended for processes with high breakage rates, fine filaments, frequent colour changes or in general when demanding processes take up an increasing share in the business. "The product mix is decisive for the choice of technology," sums up Alfred Czaplinski, Sales Manager BCF at Oerlikon Neumag. "We are happy to advise on the optimal solution and offer both single-end and three-end plant technologies." 

Good business at the Domotex Hanover, Germany

In the run-up to the trade fair, the Domotex Hanover in mid-January was already proving to be a promising harbinger. With four lively trade fair days and contract conclusions in the lower double-digit million euro range, mainly from the European and Asian markets, the order intake for Oerlikon Neumag was very good.

Amongst a record number of exhibitors at this October’s Yarn Expo Autumn, the debut BCI Pavilion as well as the Sateri Pavilion and Birla Planet Pavilion that include eco-friendly products are certainly amongst the highlights this year. Better Cotton Initiative (BCI) is a global organisation with more than 1,000 members including spinners, weavers and garment manufacturers throughout the entire cotton sector. It aims to promote sustainable cotton production, benefiting workers, customers and the environment as a whole. They will form the BCI Pavilion in Yarn Expo for the first time, with five spinners showcasing their cotton yarn manufactured with eco-friendly cotton.

Sateri is a well-known brand in China which specialises in viscose rayon. This natural and high-quality fibre is made from trees grown on renewable plantations. They are the largest producer of viscose fibre in China with three mills and an annual capacity of 550,000 tons, and also have Oeko-Tex certification. This October, nine other domestic exhibitors will form the Sateri Pavilion to demonstrate their comfortable textiles and skin-friendly hygiene products made from viscose fibre.

With over 50 years of experience in manufacturing cellulosic fibres, Birla Group strives to provide greener, purer and safer products to its customers. The Group has operated in China for three years now, and values Yarn Expo’s effectiveness in helping them to promote their brand and attract a wide range of buyers. “We managed to get connected with a number of downstream buyers at the fair. We have introduced our company and products to them that there is great chance for future cooperation.” said Mr Peter Dong, Senior Manager of Aditya Birla Group.   Coming back this year, the Birla Planet Pavilion will feature three of their highlighted fibres – Birla Viscose, Birla Modal and Birla Spunshades at the fair.

Six special display zones cater to latest industry trends

The textile industry in China is undergoing a structural change with keen competition, so domestic suppliers have to develop innovative and quality products to satisfy the ever-changing markets. To match the specific needs of various buyers, Yarn Expo has established six distinct display zones gathering the leading domestic companies, namely Colourful Chemical Zone, Natural Cotton Yarn Zone, Fancy Yarn Zone, Quality Wool Zone, Green Linen Zone and e-Commerce Zone.

Not only are a number of chemical fibre products with innovative, eco-friendly and health & comfort properties on offer from exhibitors, but visitors can also gain insights into product trends in these areas from the 2017/18 China Fibre Trend Area and Innovative Textile Material Forum, both of which feature in the Colourful Chemical Zone. The Natural Cotton Yarn Zone is another highlight of the three-day show, where exhibitors will showcase their natural cotton yarn and a range of functional products. Around 50 suppliers will also showcase their latest collections in the expanded Fancy Yarn Zone.
In response to the strong demand for fibre and yarn products in China and the Asian region, the coming autumn edition of Yarn Expo will double its exhibition space, and will accommodate around 500 global yarn suppliers from 13 countries and regions. Together with Yarn Expo Autumn 2017, three other textile trade fairs are held concurrently from 11 – 13 October in the same venue: Intertextile Shanghai Apparel Fabrics – Autumn Edition, PH Value and the China International Fashion Fair (CHIC).

Yarn Expo Autumn is organised by Messe Frankfurt (HK) Ltd; The Sub-Council of Textile Industry, CCPIT; China Cotton Textile Association; China Wool Textile Association; China Chemical Fiber Association; China Bast & Leaf Fibres Textiles Association; and China Textile Information Centre.
