From the Sector

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

A new non-halogenated FR compound called PAL...VersaCHARTM can achieve a new level of flame retardant performance as a coating for nonwovens and technical textiles.

PAL...VersaCHARTM has been tested to 1,950°C – the highest to date – and shown to prevent all flaming drips of polymer. Char bodies form on the compound surface, protecting against flame creation and delaying heat transfer. Rapid self- extinguishing burn behaviour protects any underlying substrate to which it is adhered.

The compound has passed ASTM E84 (Class A) with a 15/10 rating, which includes ‘clean’ smoke generation of only 2.3% of the allowable ASTM smoke limits. In addition, the compound is light weight, at a specific gravity of 1.0, and 100% non-toxic in every respect, being free from heavy metals, halogens and VOCs. 

Other properties include excellent cold crack performance, hydrophobicity, printability, extreme chemical resistance and the ability to be custom tailored for specific needs such as UV or antimicrobial performance, as volume warrants. The compound is also very competitively priced.

In addition to its use as a coating, PAL...VersaCHARTM compound can be produced as a flexible film or sheet and moulded to shape or over-moulded to most materials, including metal for corrosion resistance. As a polymeric compound it can be cast or calendered and typical durometers from 80-99A for flexible-to-high rigid formats are practical. 

Separately, an adhesive has been created which bonds to many surfaces. In internal evaluations of two laminated plies of woven carbon fibre and two plies of glass fabrics, both passed a 60 second vertical burn with no ply separation, distortion or flaming drips from the adhesive.

Dynamic Modifiers envisages many uses for PAL...VersaCHARTM, from aerospace to the protection of rigid structural materials in building interiors etc.   
 

At JEC World 2020, MECELEC COMPOSITES is a finalist of the JEC Innovation Awards in the Design & Furniture category. The Group announces the launch of a new sustainable development application on the urban design market. MECELEC COMPOSITES designed the first mass-produced flax fibre roofs for the 550 Morris columns installed by JCDecaux in Paris. “This is the first application of flax fibre BMC for mass production. The new solution combines all the advantages of composite materials, lightness and strength, with stringent environmental requirements and is adapted to the safety constraints of this kind of street furniture,” says Bénédicte Durand, Chief Executive Officer at MECELEC COMPOSITES.

A COMPOSITE ROOF THAT IS BOTH INNOVATIVE AND GREEN
The dome of the Morris columns is composed of 23 different parts, 14 of which are made from composite materials. To design the roof, MECELEC COMPOSITES developed a new RTM complex and a new BMC material, that is reinforced exclusively with a flax mat. “Today it is the only BMC with a 100% flax fibre reinforcement, which uses a partially recycled ABS resin. It was created specifically for this project and we had to work on the processes in order to adapt them to this new material,” explains Bertrand Vieille, Head of sales.
In the design, MECELEC COMPOSITES replaced the bonding process with a time-saving mechanical assembly process using an invisible fixing system.

AN ECO-FRIENDLY APPLICATION IN LINE WITH THE GROUP’S ECO-DESIGN CSR APPROACH
MECELEC COMPOSITES creates scalable, sustainable and environmentally-friendly street furniture. The Group is committed to developing a sustainable production process and reuses all its waste materials. MECELEC COMPOSITES R&D laboratory promotes eco-design with a process of characterisation and mechanical sizing of parts. “For this project, we imagined, created, produced and delivered a mass-produced composite application with a low environmental impact within less than a year. At the end of its lifecycle, the product completely breaks down, leaving no fibre residue,” Bénédicte Durand concludes.

The Oerlikon Manmade Fibers segment will be presenting itself at the Egy Stitch & Tex 2020 between March 5 and 8, 2020 in Cairo – with a clear focus on the needs of the African market. In Hall 1, Stand B2 The Oerlikon Barmag and Oerlikon Neumag experts will also be showcasing the comprehensive product and service portfolio of the world market leader for manmade fiber systems at the stand of Oerlikon’s representative ATAG Export & Import.

The spotlight of the Oerlikon Manmade Fibers segment’s trade fair attendance will be on two core technologies: the new generation of Oerlikon Barmag eAFK Evo texturing machines is to be unveiled within the African market for the very first time. It promises higher speeds and productivity with consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. In particular, the numerous value-added features include two that convince with cutting-edge technology: the optimized, innovative EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

The second technology focus offers new opportunities for the Egyptian market and the Middle Eastern markets in particular: with Oerlikon Neumag’s BCF S8 monocolor and tricolor system, the segment will be unveiling its new carpet yarn production flagship. Superlative spinning speeds, up to 700 individual filaments, finer titers of up to 2.5 dpf – the performance data and technological finesse of the new system have already made a huge impression at numerous trade fairs and roadshows over the past year. The tricolor’s core component is the new, patent-pending Color Pop Compacting unit (CPC-T) for even more flexible and more even color separation. With the CPC-T, individually-controllable air pressures for each color provide pre-tangling, which accentuates the colors and hence makes more than 200,000 different shades possible. Whereas it has been very difficult to manufacture strongly color-separated or color-accentuated BCF yarns from polyamide 6 to date, this will in future be possible thanks to the CPC-T system. As a result of the new design, the CPC-T is now also suitable for processes with low yarn tensions.
 
Expanded product offering for manufacturing carpet yarns
Know-how covering all relevant technologies deployed in manmade fiber spinning plants enables Oerlikon – as the world’s only manufacturer – to expand its range of products and services for making carpet yarns. The POY- and texturing-based system concept is designed for a carpet and home textiles segment that demands particularly soft and bulky polyester yarns with BCF-like properties. Here, the aim is to produce yarns with titers of max. 1300dtex and typically more than 1,000 filaments, with typical products including, for example, 1300dtex f1152, 660dtex f1152 and 990dtex f768. The machine concept comprises the well-known WINGS HD POY winder, along with the eAFK Big-V texturing machine.

In the AZL Workgroup "High-Performance SMC", a project was developed in cooperation with M-Base, the IKV and the AZL partner network for the efficient and standardized provision of engineering data for SMC. Within the scope of the project, companies can participate in the definition of the required characteristic material data, the guidelines for the production of test specimens and the test specifications.
Sheet Moulding Compounds (SMC) are used in various application areas such as vehicles, electronics, construction and infrastructure.

Driven by the requirements to reduce the production costs of lightweight components, a new generation of SMC components with high mechanical properties is of highest relevance. SMC offers enormous potential to realize structural components with good lightweight characteristics at significantly reduced costs compared to conventional continuous fiber-reinforced components.
In order to further establish SMC in broad industrial applications companies participating within the AZL Workgroup recognized the value of a data bank for data harmonization of SMC to provide the possibility of easily finding the right material with its characteristics for the needed specific requirements.

“The segment of SMC is with 250,000 tons production per year the largest composites market in Europe. I am very pleased that we start now with the project of data harmonization along the complete value chain. The goal is to have a similar data base as already established by Campus® for thermoplastics and thermoplastic composites. Only with a reliable set data we can convince the engineering experts to use SMC in a larger variety of applications,” says Dr. Michael Effing, Chairman of the Board of AVK and Composites Germany.

As of right now a databank for engineered thermoplastic materials (by Campus®) already exists and is offering an immense value.
Under the lead of M-Base, Dr. CEO Erwin Baur who has successfully established the CAMPUS database, the AZL, IKV and companies along the value chain of long fibre reinforced SMC initiated to build a CAMPUS-compatible data structure and material characterization methodology during the High-Performance SMC Workgroup Meetings.

Effiziente Lösungen und umfassendes Technologiewissen für die anspruchsvolle Filtrationsaufgaben stellen die Experten von Oerlikon Nonwoven vom 26. bis zum 28. Februar auf der FiltXPO 2020 in Chicago, USA dem internationalen Fachpublikum vor (Stand # 420).

Die Meltblown Technologie gehört zu den effizientesten Methoden bei der Erzeugung sehr feiner und hoch abscheidender Filtermedien aus Kunststofffasern. Neue, einzigartige und höchst anspruchsvolle Filtermedien lassen sich dank der optimierten Meltblown-Technologie von Oerlikon Nonwoven einfach herstellen. Diese zeichnet sich durch eine konstante Schmelzedruckverteilung bei gleichbleibender Verweilzeit über die gesamte Breite des Spinnbalkens hinweg aus. Zudem vermeidet die neuartige Führung und Verteilung der Prozessluft außerhalb des Breitschlitzverteilers der Oerlikon Nonwoven Technologie sogenannte Hotspots. Dies sorgt insgesamt für besonders homogene Vlieseigenschaften und Flächengewichte auch bei empfindlichen Rohstoffen.

Die Beladeeinheit aus dem Hause Oerlikon Nonwoven punktet gegenüber den zurzeit am Markt verfügbaren Konzepten mit ihrer hohen Flexibilität bei der Aufladung unterschiedlichster Vliesapplikationen. Der Anwender kann zwischen einer großen Anzahl an Variationsmöglichkeiten frei wählen und je nach Filterapplikation die optimale Beladungsmethode einstellen. Mit der Beladeeinheit von Oerlikon Nonwoven können so auch Filterklassen im Bereich EPA und HEPA hergestellt werden.

Die neue Formierzone sorgt für eine verbesserte Gleichmäßigkeit bei der Vliesbildung über die gesamte Breite auch bei hohen Spinngeschwindigkeiten und speziellen Polymeren sowie Polymerkombinationen. Durch die neu gestaltete Ablage wird außerdem erreicht, dass am Ende ein geringerer Vlieskantenabschnitt notwendig ist. Die neu entwickelte Mixed-Fiber Technologie ermöglicht die Kombination verschiedener Filamentquerschnitte und -polymere, um z.B: ein ideales Filter- und Plissierverhalten einstellen zu können.

Brandlast-optimiert nach A1-s1, d0: Distec verbessert Monitore für Sicherheit auf Flucht- und Rettungswegen
Die Distec GmbH Spezialist für TFT-Flachbildschirme und Systemlösungen für industrielle und multimediale Applikationen – bietet ihre bewährten Brandlast-optimierten Monitore jetzt auch als neue BLO-Line in der höchst möglichen Brandschutzklasse A1-s1,d0 nach DIN EN 13501-1:2019-05 an. Die Monitore gibt es in den Größen von 24 bis 65 Zoll und optional auch mit Touchscreen. Zusätzlich kann jeder Monitor mit einer internen PC-Lösung ausgerüstet werden. „Die neue BLO-Line-Serie eignet sich als Informations- und Wegeleitsystem auch in öffentlichen Bereichen mit besonderen Anforderungen an den Brandschutz, wie Flucht- und Rettungswegen“, erläutert Matthias Holst, Head of Division Monitor Solutions der Distec. „Die Monitore lassen sich in derselben Brandschutzklasse einordnen wie ein Ziegelstein, das heißt sie tragen nicht mehr zur Brandlast bei als die Wände, an denen sie hängen. Wir sind der erste Anbieter von Monitoren in dieser höchsten Sicherheitskategorie.“ Separate Brandschutzgehäuse sind für die neue BLO-Line nicht mehr notwendig. Damit sind die Monitore nicht nur optisch ansprechender, sondern auch kosteneffizienter sowie leichter zu montieren und zu handhaben. Sie sind ideal als Informationsanzeigen in Bereichen mit strengen Brandschutzbestimmungen in Industriebauten und in öffentlichen Gebäuden wie beispielsweise Krankenhäusern, Universitäten, Schulen, Bahnhöfen und Flughäfen.

Sicherheit durch optimalen Brandschutz
Die neuen Monitore der BLO-Line sind mit einem Brandschutzglas versehen und haben ein stabiles Gehäuse aus Stahlblech. „Wir haben es durch die sorgfältige Auswahl an Komponenten und Materialien sowie eine feuerhemmende Konstruktion geschafft, dass unsere Monitore im Falle eines Feuers so wenig wie möglich zur Brand- und Rauchentwicklung beitragen“, ergänzt Matthias Holst. Die langlebigen Displays sind für den 24/7-Betrieb ausgelegt. Optional stattet Distec die Monitore mit einer hohen IP-Schutzklasse und einer Löschkartusche aus. Diese kleine Kartusche im Innern des Monitors ist mit einem speziellen Gas gefüllt. Bei großer Hitze bricht die Röhre und setzt das Löschgas frei, das das Feuer eindämmt.

Distec bietet die BLO-Line parallel zu den bisherigen Brandlast-optimierten Monitoren an, die nach B-s1, d0 zertifiziert sind. Alle Monitore sind wahlweise zur externen Ansteuerung oder mit einem integrierten PC erhältlich. Standard ist eine Lieferung für die Montage im Querformat, bei Bedarf liefert Distec jedoch alle Versionen auch für die Montage im Hochformat aus. Jedem Monitor liegt ein Zertifikat bei, das die Brandklasse für das Gerät bestätigt.

Das Brandverhalten, also die Entzündbarkeit und Brennbarkeit der Monitore, wurde in Anlehnung an das SBI-Verfahren nach DIN 13823:2015-02 ermittelt. Der Brandversuch wurde nach der europäischen Norm gemäß DIN EN13501-1:2019-05 durchgeführt. Die Geräte erreichen nicht nur die höchste Brandschutzklasse nach A1-s1, d0, sondern sie erfüllen und unterschreiten sämtliche Anforderungen im Brandversuch: Sie sind nicht brennbar und besitzen die Eigenschaften „keine/kaum Rauchgasentwicklung und kein brennbares Abtropfen/Abfallen". Der Display-Spezialist hat den ersten BLO-Monitor als Pionier bereits 2015 entwickelt.

Höchste Brandschutzklasse für BLO-Line-Monitore
Distec präsentiert die neuen BLO-Line-Monitore und weitere Highlights vom 11. bis 14. Februar 2020 auf der Integrated Systems Europe ISE in Amsterdam am Stand R130 in Halle 10. Zudem stellt David Bittner, Product Marketing Manager bei Distec, die Brandlast-optimierten Monitore in einer Präsentation am 26. Februar 2020 um 13:35 Uhr auf der Electronic Displays Conference im Rahmen der embedded world Messe in Nürnberg vor.
