The Cetex Institut gGmbH, the thermoPre ENGINEERING GmbH and The FilamentFactory GmbH cooperate in the development, production and marketing of novel hybrid materials. The cooperation agreement signed on October 2, 2020 in Chemnitz takes the collaboration to a new level. "We are pleased to be able to supply the hybrid rovings to the end user not only in an application-specific manner, but also to offer the engineering for subsequent component applications, including the prototyping of the FRP components," says Sebastian Nendel, Managing Director of Cetex.

Patented process for the production of hybrid rovings
In the last 3 years the Cetex Institute has developed a plant technology for the production of hybrid rovings. By means of the patented process, different material combinations can be produced according to customer specifications. Material combinations of reinforcing fibers (glass, basalt, carbon, aramid or high-strength polymer fibers) can be combined with matrix fibers (PP, PET, PA, PPS, PEEK), but also special combinations of different reinforcing fibers or the combination of reinforcing fibers with metal fibers. Advantages of the new hybrid roving are the torsion-free and completely stretched fiber layer and the associated optimal utilization of the properties of the reinforcing fibers, as well as a very good homogeneity, whereby excellent processing can be achieved in later process steps.

Series production as next step
The next goal is clearly defined: Under the agreement, the process is to be jointly developed further by the project partners and transferred to series production. These joint activities form the basis for many years of intensive cooperation in this new field.

a leading Asian large-scale manufacturer of manmade fibers and polymers has invested in a new Oerlikon Nonwoven meltblown system. The recently-signed contract comprises a 2-beam system for manufacturing filtration nonwovens – predominantly for medical products such as face masks – with a nominal capacity of up to 1,200 tons of nonwovens a year. The commercial production launch has been scheduled for the fourth quarter of 2020.

The 2-beam system has an operating width of 1.6 meters and is equipped with the new patented Oerlikon Nonwoven electro-charging unit. The Oerlikon Nonwoven meltblown technology is recognized by the market as being the technically most efficient method for producing highly-separating filter media made from manmade fibers, particularly in conjunction with electrostatic charging and with extremely low-pressure loss. Electro-charging the filter nonwovens allows the manufacture of sophisticated EPA- and HEPA-class filter media as well as media that comply with the requirements of N95-, FFP2- and FFP3-class respiratory masks.

The demand for filtration nonwovens for medical applications has risen tremendously across the globe since the outbreak of the Sars-CoV-2 (coronavirus) epidemic, presenting all manufacturers with huge challenges. A meltblown system will be commissioning at the site of a leading Western European nonwovens producers as early as the second quarter of 2020. This system will be deployed exclusively in the manufacture of nonwovens for respiratory masks.

Due to the current state of emergency with regards to the local supply of face masks, Oerlikon Nonwoven is currently using its own laboratory system to produce electrostatically-charged filter media which are being sent to local small businesses and companies for the manufacture of face masks. 

The Oerlikon Nonwoven experts will be presenting efficient solutions and comprehensive technology know-how for challenging filtration tasks to an international trade audience at the FiltXPO 2020 in Chicago, USA (Stand # 420), taking place between February 26 and 28.

Meltblown technology is one of the most efficient methods for producing very fine and highly-separating filter media made from manmade fibers. New, unique and highly-sophisticated filter media are easy to manufacture thanks to Oerlikon Nonwoven’s optimized meltblown technology. This process is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam, Furthermore, the novel guidance and distribution of the process air outside the coathanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures particularly homogeneous nonwoven properties and basis weights even in the case of delicate raw materials.

The Oerlikon Nonwoven charging unit stands out against other concepts currently available on the market. Users can freely choose from a large number of variation possibilities and set the optimum charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA- and HEPA-class filter media.

The new forming section ensures improved nonwoven formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixedfiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.

Market and technology analysis confirms big potential for tape inserts in the injection molding process. Following the finalization of a major consortial project led by the Aachen Center for Integrative Lightweight Production (AZL) and the Institute for Plastics Processing at RWTH Aachen University (IKV), the result is clear: tape inserts offer enormous potential for injection molding parts. For suitable components, product costs and component properties can be positively influenced.

In cooperation with 20 industrial partners, the two renowned Aachen research institutes AZL and IKV carried out a detailed analysis of tape inserts in injection molded components over a period of eight months. The tapes, which are a few tenths of a millimeter thick, are continuous fibers, typically made of glass or carbon, completely impregnated and embedded in a thermoplastic matrix. The tapes can be precisely aligned to the loads in a component and are used primarily in high-performance applications with the aim of weight reduction. The aim of the conducted analysis was the identification of potential applications and the estimation of a wider range of applications.

The project was divided into several phases: Phase I was used to identify the current status. In 20 interviews with representative companies of the injection molding industry, the researchers gathered why tape inserts have rarely been taken into account so far, when defining the material concepts to be analyzed. The lack of information about the material class, the procedure and tools for the development process and the necessary production technologies were cited as major challenges. This is where the consortium will take action and provide comprehensive information during the “Technology Information Day” on the extensively prepared state of the art and the high degree of maturity of the supply chain. Based on the status quo, they developed a methodology for analyzing the technological and economic potential of tape inserts in injection molding applications.

Both the previous results and the planned follow-up projects are the subject of the “Technology Information Day" at K 2019, to which the companies involved in the study, the AZL and IKV, invite all companies along the value chain, from raw material manufacturers to injection molders to OEMs. (Date: 18th October 2019, 10:00 am to 1:30 pm, Trade Fair Düsseldorf CCD South, Room 002).

The consortium, amongst others consisting of Asahi Kasei Europe GmbH, BASF SE, Borealis AG, BÜFA Thermoplastic Composites GmbH & Co. KG, ENGEL AUSTRIA GmbH, Huesker Synthetic GmbH, LG Hausys R&D Center, Mitsui Chemicals, Nippon Electric Glass, Polyscope Polymers BV, POLYTEC GROUP, Simcon kunststofftechnische Software GmbH, SABIC and Toray International Europe GmbH, is inviting to the “Technology Information Day” at K 2019. The goal is to inform about the technology and to identify topics for future collaboration.

• Borealis’ EverMinds™ ambition moves industry one step closer to plastics circularity thanks to new recycling technology and improved recyclate
• Borealis also announces significant material improvements to existing Purpolen® recyclate materials

Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers, announces the introduction of a new plastics recycling technology, Borcycle™. This evolving technology will be used to produce high-quality compounds made of recycled polyolefins (rPO) such as the newly-launched Borcycle™ MF1981SY, an rPO with over 80% recycled content intended for use in visible appliance parts. Borealis also announces a series of significant material improvements to existing recyclates in the established Purpolen™ brand portfolio. These market launches and product improvements are important technology advancements and thus accelerate the transformation to a circular economy of plastics. Borealis and its wholly-owned subsidiary, mtm plastics, will showcase the new Borcycle technology and recyclate innovations at the K 2019 in October.

Borealis is leading the industry by applying its Visioneering Philosophy™ to the development and implementation of novel polyolefins-based solutions that enable plastics reuse, recycling, and recovery, and by designing for circularity. These wide-ranging activities are gathered under the symbolic roof of EverMinds™, the Borealis platform dedicated to promoting a more circular mind-set in the industry. By capitalising on its profound expertise in virgin polyolefins and collaborating with value chain partners, Borealis keeps discovering new opportunities for business growth within the circular economy.

Advancing technology to bring about polyolefin circularity

The new technology, Borcycle, transforms polyolefin-based waste streams into recyclate material such as pellets. As a transformative technology, it complements the existing Borealis virgin polyolefins portfolio with a range of pioneering, circular solutions. It unites state-of-the-art technology with the profound Borealis polymer expertise gained over decades.

As a scalable and modular technology, Borcycle has been developed to meet growing market demand for high-quality recyclate. Leading appliance brand owners, for one, have pledged to increase the amount of recycled plastics in their goods. Yet until recently, producers have not been able to rely on a consistent supply of high-quality recyclate. The Borcycle technology will help address this challenge. Compounds made using the Borcycle technology deliver high performance, add value and offer versatility. Producers and brand owners in a range of industries will profit from the availability of high-quality recyclate that helps them meet environmental and regulatory challenges.

“Advancing technology is crucial if our aim is to implement value-creating solutions in the circular sphere,” claims Maurits van Tol, Borealis Senior Vice President, Innovation, Technology & Circular Economy Solutions. “‘Building tomorrow together’ means innovating, collaborating, focussing on the customer, and above all – taking action. The launch of our new recycling technology Borcycle is tangible proof of our commitment to achieving plastics circularity.”

New and improved recyclate for high-end applications

Borcycle™ MF1981SY is the first of several upcoming launches of rPO solutions made under the umbrella of the Borcycle technology. Borcycle™ MF1981SY will be available to Borealis customers in Europe. The compound is an exciting addition to the rPO portfolio because it is a 10% talc-filled compound that contains over 80% recycled material. It offers an ideal balance between stiffness and impact. The compound is especially suited for use in visible black parts, for example in small appliances.

Like its relatives in the mtm plastics family of recyclate materials, Borcycle™ MF1981SY is a truly sustainable offering. Recyclates from mtm save approximately 30% of CO2 emissions compared to virgin materials.

A number of significant improvements have been made to existing recyclate grades in the Purpolen portfolio.

“Mechanical recycling is presently a most eco-efficient method to implement the principles of the circular economy,” explains Guenter Stephan, Head of Mechanical Recycling, Borealis Circular Economy Solutions. “Borealis and mtm plastics are leveraging their respective areas of expertise to make significant progress in achieving polyolefin circularity by upscaling recycling output and ensuring the reliable supply of high-quality plastics recyclate for European producers, in particular.”

• 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.
