LANXESS commissions two additional production lines for composite material Tepex

At its site in Brilon, Germany, Bond-Laminates GmbH – a wholly owned subsidiary of specialty chemicals company LANXESS – has commissioned two new production lines for Tepex continuous-fiber-reinforced thermoplastic composites. “We have increased our capacity for manufacturing Tepex by around 50 percent and, in doing so, are responding to the strong demand in the mass production of highly stressable components for lightweight vehicles and consumer electronics,” says Dr. Christian Obermann, Managing Director of Bond-Laminates. To accommodate the expansion from six to eight production lines, a new hall covering around 1,500 square meters was constructed. The total investment ran to the mid single-digit millions and also comprised three cutting machines, including a new four-head waterjet cutting machine for prefabricating component cuts.

Lightweight structural construction of high-performance parts

Tepex is becoming increasingly popular in the automotive industry for the large-scale production of lightweight structural components such as frontend and bumper brackets, brake pedals and underbody paneling components. One recent example involved two electrically adjustable single rear seats for a variant of the Audi A8, whose seat shells are manufactured in a hybrid molding process using the polyamide-6-based Tepex dynalite. The seat shells are around 45 percent lighter than a comparable metal version.

Huge potential in electric vehicles

LANXESS also sees potential for Tepex to be used to produce backrests and armrests as well as seat shells for new, highly complex seating concepts in autonomous cars or for comfort seats for shuttle, VIP and family buses. Electric vehicles offer further attractive potential for Tepex. “The spectrum of applications ranges from brackets for frontends, doors and bumpers, luggage compartment recesses, battery housings and brackets for electrical and electronics modules through to structural components in the “greenhouse” section and structural trims in the underbody area to protect the battery,” says Henrik Plaggenborg, head of Tepex Automotive at LANXESS.

Typical applications of Tepex in consumer electronics include the thin-walled yet exceptionally strong and rigid structural components for cellphones, tablets, laptops and TVs – components that also have to meet strict aesthetic requirements regarding design and haptics. In the sports sector, Tepex is used for example in the manufacture of shoe soles, bicycle components, ski boots, body protectors and helmets.
