Materialica Award in gold for tribond from thyssenkrupp. Duisburg steel producer honored for pioneering work in the area of steel composites

Lightweighting with steel is a key concept for future vehicle generations. OEMs, suppliers and materials developers increasingly face the challenge of developing new ideas to meet conflicting requirements with regard to price, safety, quality and design. With completely new property profiles and significant weight reduction potential, the newly developed composite tribond offers a possible solution. For this pioneering innovation, thyssenkrupp has now been presented with the Materialica Award at eMove360° Europe, the international trade show for mobility.

Material concept for the future production-ready

The materials specialists from thyssenkrupp Steel have already opened up significant light-weighting potential with their modern high-strength and ultrahigh-strength multi-phase steels. tribond, designed as a modular system, now offers further weight reduction potential for the hot forming process. What is revolutionary about the new composite is its multilayer structure that permits completely new property profiles. The tribond 1200 and tribond 1400 variants now ready for production combine an inner layer of high-strength steel and outer layers of formable, ductile steel. This permits maximum strength and high ductility to be realized in one part, something currently not possible with homogeneous materials. tribond 1200 was specially developed to absorb as much energy as possible in the event of high axial stresses, such as those caused by a collision. Typical uses include longitudinal mem-bers in cars. By contrast, the higher-strength tribond 1400 was specifically developed for parts subjected to high bending stresses such as B-pillars. Both variants enhance occupant safety in cars. To validate the material’s behavior in the event of a crash, the Duisburg-based company has installed a simulation process that calculates and tests the desired property profiles in advance.

High process reliability in production

High process reliability provides further advantages for customers: In the past, conflicting material properties such as high strength and ductility could only be realized using complex technological processes such as tailored tempering. “tribond has the advantage for cus-tomers that the complexity switches back to the material, in this case to the production of the multilayer slabs. Customers can process tribond directly on their existing production lines,” explains André Matusczyk, head of the Auto business unit at thyssenkrupp Steel Europe.
