An emerging application for Lanxess' (Leverkusen, Germany) Tepex continuous-fiber-reinforced thermoplastic composite is the door module carrier for a compact-class vehicle from an international automotive manufacturer. Lanxess recently received a contract from German system supplier Brose Fahrzeugteile GmbH & Co. KG to supply the carrier’s manufacturer, ElringKlinger AG, with its composite material. “The structural component exemplifies the tremendous potential opened up by our composite in cost-effective lightweight design. With our know-how in materials, virtual component design and simulation of the manufacturing process, we’ve made a key contribution to this successful development,” says Henrik Plaggenborg, head of the technical marketing & business development Tepex Automotive group. Lanxess subsidiary Bond- Laminates, which develops and manufactures Tepex, will supply ElringKlinger in Europe with the Tepex composite sheet.

The component is the result of a close partnership between Brose, ElringKlinger and Lanxess over a number of years. The weight has been cut by around 1.6 kilograms per vehicle compared with injection molded component designs. “With four door modules, weight savings of approximately five kilograms per vehicle are possible compared with a steel version,” says Plaggenborg.

The door module carrier is produced in a hybrid molding process using forming and back-injection of Tepex directly in the injection mold. “The one-shot process industrialized by ElringKlinger eliminates the forming tool, while also enabling cost-cutting integration of functions. These two things are the key to making the component cost-effective,” says Harri Dittmar, project manager in the technical marketing and business development Gdoup.

Tepex has already established itself in various series applications in structural lightweight automotive design. For example, it is used to produce front-end carriers, bumper beams, infotainment brackets, underfloor protection paneling, brake pedals, battery consoles, seat shells and seat backrests. 


  • Composite leaf springs: Saving weight in production

    Fast-reacting resins and speedier processes are making economical volume manufacturing possible.

  • The fiber

    The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.

  • The matrix

    The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here’s a guide to selection.
