From the Sector

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, along with its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will be participating in the Techtextil exhibition in Frankfurt, Germany from the 21st till the 24th of June 2022.

On display will be SHIMA SEIKI’s latest innovation in flat knitting technology as applied to the field of technical textiles—a prototype weft knitting machine capable of multi-axial yarn insertion. Fabrics produced on this machine use inlay technique for the production of hybrid textiles that combine the stretch characteristics of knitted fabrics with the stability of woven textiles, suited to various technical applications. To this, warp yarn is inserted to further expand its capability to produce 3D-shaped carbon fiber and composite preforms directly on the machine. This is made possible by taking advantage of the fact that flat knitting as a textile production method is capable of producing end products that are shaped-to-form and with added thickness. Compared to current methods of preform production, savings in post-processing time, material, labor and associated costs are immense, realizing efficient and sustainable production. SHIMA SEIKI’s own yarn unwinding technology is also used for optimum yarn feed and tension for use with technical yarns that are otherwise difficult to knit. Industrial textile samples knit on the multi-axial machine will also be available for examination on-site.

SHIMA SEIKI's SDS®-ONE APEX4 3D design system will be available for demonstrations as well. Of particular interest should be its ultra-realistic simulation capability that realizes Virtual Sampling. When countless variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time, cost and material normally associated with producing actual samples for each variation. When approved, the same data can be converted to machine data for immediate knitting, significantly reducing lead times.

Computerized knitting machine manufacturer SHIMA SEIKI MFG., LTD. will participate in the SIMATEX exhibition in Buenos Aires, Argentina from 30th of May - 2nd of June 2022.

SHIMA SEIKI will exhibit a wide range of its products, including proposals in seam-free WHOLEGARMENT® knitting technology that offers an alternative to labor-intensive manufacturing in the South American market. Three MACH2VS machines, capable of knitting WHOLEGARMENT® knitwear using every other needle, will be shown in 12, 16 and 18 gauge configurations. The N.SVR workhorse series improves on the SVR series, resetting the industry benchmark for shaped knitting. The N.SVR123SP featuring a special loop presser bed that can produce hybrid inlay fabrics with both knit and weave characteristics. Shown in 18 gauge at the SHIMA SEIKI booth, N.SVR123SP will also feature the special i-Plating option, capable of alternating yarn colors in any pattern, producing jacquard-like designs using plain jersey stitch for even greater diversity in knit design. N.SSR112 improves on the SSR series and continues to offer industry-leading technology in an economical yet reliable package made in Japan.

Demonstrations will be performed on SHIMA SEIKI's SDS®-ONE APEX4 design system. At the core of the company’s “Total Fashion System” concept, SDS®-ONE APEX4 provides comprehensive support throughout the production supply chain, integrating production into one smooth and efficient workflow from yarn development, product planning and design, to production and even sales promotion. Especially effective is the way SDS®-ONE APEX4 improves on the design evaluation process with its ultra-realistic simulation capability, whereby virtual samples minimize the need for actual sample-making. This realizes significant savings in time, cost and material, contributing to sustainable manufacturing.

SHIMA SEIKI ITALIA S.p.A., Italian subsidiary of leading Japanese computerized knitting solutions provider SHIMA SEIKI MFG., LTD., will exhibit at the 90th edition of the Pitti Immagine Filati exhibition in Florence, Italy.

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.
