• First glass fiber based leaf spring project in series by Ford worldwide
• From development to serial production

Since midyear, SGL Carbon has produced longitudinal leaf springs made of glass fiber-based composite for Ford Transit rear axles in series. The springs are used in combination with the Transit Skeleton chassis. Thus, they are applied where high payloads play an important role, for example in caravanning models or specific commercial vehicle variants of the Transit. In comparison to conventional leaf springs, the innovative composite leaf spring weighs about 50 percent less while offering increased security standards. The serial application is supported by a one-to-one compatibility with standard steel springs.

In der Kategorie „Industrie & Material“ setzte sich das Thüringische Institut für Textil- und Kunststoff-Forschung Rudolstadt e.V. (TITK) im diesjährigen Wettbewerb gegen zahlreiche Mitkonkurrenten durch. Die flexiblen, metallfreien Heizfolien mit integriertem Überhitzungsschutz überzeugten die Jury unter Vorsitz von Prof. Dr. habil. Ulrich S. Schubert. Institutsdirektor Benjamin Redlingshöfer wertet den am 27. November 2019 in Weimar verliehenen Preis als herausragende Auszeichnung für eine exzellente Leistung in der wirtschaftsnahen Forschung sowie für den erfolgreichen Transfer von Forschungsergebnissen in die Industrie.

Weimar / Rudolstadt – Der Rudolstädter Wettbewerbsbeitrag lautete „PTC-ThermoMat“ – Effizientes Thermomanagement mittels flexibler, metallfreier Heizmaterialien auf Polymerbasis". Die Heizfolien mit dem sogenannten PTC-Effekt waren in diesem Jahr auch auf der Hannover Messe vorgestellt worden. Die Abkürzung PTC steht für „positive temperature coefficient“ und beschreibt die starke Zunahme des Widerstands mit der Temperatur. Getreu diesem Prinzip reduziert die Heizfolie ihre Leistung selbst, sie bringt also ihre eigene Thermosicherung mit. Ganz ohne zusätzliche Steuerungstechnik schützt sie so empfindliche Güter, Personen und Aggregate vor Hitzeschäden.

Das leitfähige Material kommt mit einer geringen Energiezufuhr aus und lässt sich in verschiedensten Dicken herstellen. Es ist flexibel, thermisch verformbar und unempfindlich gegenüber Strukturverletzungen. Verwendung finden kann es nicht nur in Elektrofahrzeugen, wo sich völlig neue Bereiche im Innenraum oder auch im Motorraum effizient erwärmen lassen. Einsatzgebiete eröffnen sich auch in elektrischen Fußboden- und Wandheizungen, Operationstischen, Wasserbetten, Sessel-Liften oder Aquarien.

„Erste Industriepartner haben wir bereits für diese Technologie“, sagt TITK-Direktor Benjamin Redlingshöfer. „Wir würden uns freuen, wenn der Innovationspreis dazu beiträgt, weitere Interessenten auf unsere Innovation aufmerksam zu machen. Möglicherweise können wir gemeinsam noch ganz andere Anwendungsfelder ausloten.“

Der geschäftsführende Direktor zeigt sich stolz auf das gesamte Team der TITK-Gruppe. Er dankt allen Forscherinnen und Forschern für ihr tagtägliches Engagement und gratuliert besonders dem verantwortlichen Team der Abteilung Funktionspolymersysteme mit Abteilungsleiter Prof. Dr. Klaus Heinemann, dem zuständigen Projektleiter Dr. Mario Schrödner sowie Dr. Thomas Welzel, Hannes Schache und Frank Schubert.

• Glass fiber textiles for helicopter type H145
• First ever material supply for primary structural components in the aerospace segment

Since August of this year, SGL Carbon delivers two special glass fiber textiles, so-called non-crimped fabrics, for the new version of helicopter model H145 from Airbus Helicopters. These materials are used in the new, especially efficient five-blade rotor. Developed in close collaboration with Airbus Helicopters, the material has been qualified for the application for the next years to come.  

Thanks to their unidirectional fiber orientation, the fabrics are extremely resistant, providing optimal support for the new geometry of the especially long H145 rotor blades. The fabrics are manufactured at the SGL Carbon site in Willich near Düsseldorf in a multi-stage process and delivered to Airbus Helicopters in Paris.  

“The order emphasizes our growing presence in the aerospace business. With the fabrics for Airbus Helicopters, we have realized, qualified, and started serial production for a material concept for primary structural components for the first time,” underscores Dr. Andreas Erber, Head of the Aerospace segment in the business unit Composites – Fibers & Materials at SGL Carbon.

The current deliveries are part of a framework contract with Airbus Helicopters, intended to gradually intensify collaboration. Besides the current development of materials for helicopter components, Airbus Helicopters and SGL Carbon have worked together in the area of component material processing for Airbus group aircraft doors for years. In addition, Airbus and SGL Carbon are jointly involved in various associations and research projects in the area of components, such as Carbon Composites e.V.

The current generation of PFAFF shoe post-bed machines, that is viewed in the industry as the mother of all shoe machines, is the most frequently copied industrial shoe post-bed machine. Being copied means that PFAFF have done a lot on the machine that is good. However, it also means that the German machinery supplier always have to be one step ahead with regard to technology and that bit better with regard to quality. This is what the market expects, this is what the customer expects from PFAFF. The new “Programmable thread tension” is the latest feature of the electronic shoe post-bed series PFAFF 1571/1574/1591. The key benefit of “programmable thread tension” is that suitable thread tensions can be applied for different material thicknesses and/or for different seam sequences (as these can be programmed on electronic machines). The tensions can be accessed and/or set via a knee switch or stitch counting. Manual setting of the thread tension, as is common with current shoe machines, is no longer necessary with the programmed thread tension. This increases the quality and significantly improves the process reliability. “Programmable thread tension” is initially available as an option on the electronic machines 1571/1591.

By the year 2050, the Lenzing Group will no longer generate any net CO2 emissions.

Lenzing‘s Management Board has now resolved to invest EUR 40 mn to expand the production of the raw material sulfuric acid at the Lenzing site. This comprises an important milestone on the path towards climate neutrality. In the future, a new air purification and sulfur recovery plant will not only optimize the company’s self-sufficiency for this raw material and enhance process reliability but improve environmental protection within the context of a clear forward-looking strategy.

Improved exhaust emission performance

The new plant represents an important contribution towards implementing the sustainability strategy of the Lenzing Group, and also helps to ensure an even higher level of environmental compatibility of all production operations at the Lenzing site. The application of state-of-the-art technologies will further improve exhaust emission values. Furthermore, the new facility will help further reduce the use of fossil fuels by generating steam which will, in turn, be converted into electricity. In this way, it will also support the energy self-sufficiency of the company’s operations in Lenzing.

Improved CO2 scorecard

As a result, the production plant in Lenzing will reduce its annual CO2 emissions by 15,000 tons. This is an important step towards further advancing the company’s ambitious plans in the coming years and also strengthen Lenzing’s leadership role as a driver of ecologically sustainable industry. “On the basis of these investments, Lenzing is taking the next step in achieving its climate targets. At the same time, it will also reach a significantly higher level of autonomy with respect to a vital raw material”, states Stefan Doboczky, Chief Executive Officer of Lenzing.

Als akkreditiertes Prüflabor nach DIN EN ISO / IEC 17025 hat die OMPG mbH, ein Unternehmen der TITK-Gruppe Rudolstadt, das jüngste Überwachungsaudit wieder erfolgreich bestanden.
