As an introduction, speakers - including CTC/Airbus and Teijin - presented different possible applications for SMC and BMC components, including aircraft interiors, bicycle boxes, and applications in e-mobility. The topic of sustainability was broadly covered, highlighting recycling solutions and experiences (Siemens, IDI, OC, AOC), the use of renewable raw materials, as well new LCA models developed by the SMC BMC Alliance (LCS),

Specifically for designers, the use of the SMC flow and curing modelling was presented (ESI, OC), SMC positioning vs. aluminium (Spartners). The second day concluded with contributions on process optimization options for component production, including speeches by Dieffenbacher, Netzsch and EBG.

AZL: Gemeinsames Projekt zu Batteriegehäusen mit 46 Industriepartnern

Gemeinsam mit insgesamt 46 Industriepartnern konnten mehrere, verschiedene Konzepte für Kunststoff-basierte Multimaterial-Batteriegehäuse erarbeitet werden, mit denen deutliche Einsparpotentiale bei Gewicht und Kosten möglich sind. Im Projektverlauf kristallisierten sich zwei wichtige Kernthemen heraus, die in Folgeprojekten gesondert behandelt werden sollen: Bodenaufprallschutz und Feuerbeständigkeit. Diese zwei Folgeprojekte starten am 26. Januar 2022. Ein Projekt zur Entwicklung und Realisierung von Prototypen für Mitte nächsten Jahres 2022 ist in Planung.

Gemeinsam mit insgesamt 46 Industriepartnern konnten mehrere, verschiedene Konzepte für Kunststoff-basierte Multimaterial-Batteriegehäuse erarbeitet werden, mit denen deutliche Einsparpotentiale bei Gewicht und Kosten möglich sind. Im Projektverlauf kristallisierten sich zwei wichtige Kernthemen heraus, die in Folgeprojekten gesondert behandelt werden sollen: Bodenaufprallschutz und Feuerbeständigkeit. Diese zwei Folgeprojekte starten am 26. Januar 2022. Ein Projekt zur Entwicklung und Realisierung von Prototypen für Mitte nächsten Jahres 2022 ist in Planung.

Batteriegehäuse gehören zu den Schlüsselkomponenten in E-Fahrzeugen und werden derzeit in der Regel aus Aluminium hergestellt. Genau diese Komponente analysierte das AZL in dem jetzt durchgeführten Projekt mit einem großen Konsortium aus Automobilherstellern, Automobilzulieferern, Rohstoffherstellern und Maschinenherstellern. „Der enorme Zuspruch aus der Industrie unterstreicht die Relevanz des Themas“, freut sich der Projektleiter Warden Schijve, der zudem sehr zufrieden mit dem Verlauf und den Ergebnissen ist. Schließlich lassen sich bis zu 36 % des Gewichts und bis zu 20 % der Kosten einsparen, wenn anstelle herkömmlicher Lösungen Multi-Material-Verbunde auf Basis von Kunststoffen zum Einsatz kommen.

Um zu den Ergebnissen zu gelangen, hat das AZL unter Mitwirkung seiner Partnerunternehmen, zu denen unter anderem Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Formosa, Hengrui, Hutchinson, IPTE, Johns Manville, Magna, Marelli und Teijin, gehörten, zunächst fünf Subkomponenten eines Batteriegehäuses definiert: die Gehäusewanne, die Bodenschutzplatte, den Crash-Rahmen, die Querbalken und den Gehäusedeckel. Außerdem analysierten die Partner insgesamt 44 marktrelevante, existierende Serienkomponenten und Konzepte genauer und erstellten eine umfangreiche Übersicht über die verschiedenen Standards sowie Anforderungen auf nationaler, internationaler und OEM-Ebene. Prämisse dabei war, gleiche oder gar bessere mechanische Kennwerte zu erreichen als bei herkömmlichen Lösungen. So sollten beispielsweise mindestens gleiche Steifigkeiten, Sicherheiten bei seitlichem Aufprall, EMI-Abschirmung sowie Flammschutz vorhanden sein. Um nun die alternativen Lösungen zu ermitteln, entwickelte das AZL 20 Designkonzepte mit unterschiedlichen Materialkombinationen. Zur Analyse und Auslegung der verschiedenen Konzepte wurden mehr als 500 FEM-Modelle erstellt und über 1.500 CAE-Simulationen durchgeführt.

Während sich Folgeprojekt 1 mit einer anwendungsbezogenen Testmethode und der Untersuchung der Sicherheit verschiedener Materialkombinationen für den Bodenaufprallschutz beschäftigt, steht in Folgeprojekt 2 die Flammresistenz verschiedener Materialien und Materialkombinationen im Vordergrund. Ziel ist es Prüfverfahren zu entwickeln, die es erlauben, die Aufprall-/Feuerbeständigkeit auf Materialebene unter Berücksichtigung der spezifischen Anforderungen an ein Batteriegehäuse im Vergleich zu Standardmaterialien zu untersuchen.

Teijin to boost Heat-Resistant Carbon Fiber Prepreg Production

Teijin Limited announced today that its carbon fiber subsidiary Renegade Materials Corporation, a leading U.S.-based supplier of highly heat-resistant thermoset prepregs, resins and adhesives for the aerospace industry, will expand its prepreg production by 2.5 times approximately. The increased capacity, which aligns with Renegade’s capacity expansion strategy at the Miamisburg, Ohio location, is the result of a USD 4 million investment made in December 2019 and the construction was started in March 2020. Operation of the new production lines will commence January 2022.

Renegade Materials' heat-resistant thermoset prepregs, resins and adhesives are well trusted by U.S. and European aircraft manufacturers and aircraft engine suppliers.

Renegade Materials will showcase its high heat-resistant thermoset prepreg at the Composites and Advanced Materials Expo (CAMX), one of the largest, most comprehensive composites and advanced materials event in North America, at the Dallas Convention Center in Dallas, Texas, from October 19 to 21.

Teijin: Tenax™ Carbon Fiber Prepreg Adopted for Next-Generation Aircraft Engine Nacelle

Teijin Limited announced today that its Tenax™ carbon fiber prepreg has been adopted for a part of nacelle, or streamlined housing, for next-generation aircraft engine to be used by Airbus. A prototype of the nacelle part, which Nikkiso Co., Ltd. is developing for Airbus’s Propulsion of Tomorrow project, will be delivered to Airbus by the end of 2021.

The Tenax™ prepreg used for the nacelle part was developed especially for aircraft applications using high-performance and rapid-curing epoxy resin. Notably, the Tenax™ prepreg can be molded at a lower temperature and in a shorter time than conventional prepregs for aircraft applications. In addition to general autoclave molding, the Tenax™ prepreg also is suited to press molding for mass production, achieving excellent quality required for aircraft applications. Furthermore, it is compatible with automated fiber placement (AFP) therefore can be combined with automatic laminating technology and short-time molding to maximize production efficiency. The excellent productivity and cost efficiency of the Tenax™ prepreg were key reasons why it was adopted for Nikkiso’s nacelle.

Teijin Carbon produces new thermoplastic PPS-Tape

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.
