Merge Technologies for Multifunctional Lightweight Structures

Top-level research for international visibility and performance

Welcome to Germany's first and only Federal Cluster of Excellence in the field of lightweight structures. Lightweight construction is a key technology of the future. Wherever masses have to be moved, the optimization of weight is a main focus in order to save raw materials and energy. Thus, it is the aim of the Cluster's research to merge basic technologies suitable for mass-production, comprising plastic, metal, textile and Smart Systems for the development of resource-efficient products and production processes. More than 100 researchers and technicians from a total of six interacting research domains are currently working on the implementation of this project, which is funded by the DFG with 31 million Euros in the period 1st November 2012 to 31st October 2017. Join us now...


Open day 30.05.2015 | 10:00 - 15:00 clock

2nd IMTC - Registration is now open

Register now.

The conference is aimed at experts from academia and industry who contribute their knowledge to the research and development of lightweight structures and to the corresponding manufacturing technologies. For the second IMTC we want to foreground the interdisciplinary exchange between scientists, researchers and users. In addition to the versatile sessions, once again you will have plenty of opportunities to engage in an open exchange with representatives of different disciplines and to network with experts and peers.

JEC Europe Paris 2015 - Fair report

From 10 to 12 March, 2015, the most important European Composite Fair, the JEC Europe in Paris, took place for the 50th time. The Federal Cluster of Excellence MERGE presented itself together with the Endowed Chair Textile plastic composites and its founding company SLK Schwergewebekonfektion Lichtenstein GmbH.

Using the example of a vehicle seat headrest demonstrator, the Endowed Chair TKV presented the results achieved so far by the Federal Cluster of Excellence MERGE in the process engineering of merging plastic and textile reinforcing structures for innovative multi-material lightweight design.

Special attention attracted the OLU-Preg®-textile-reinforced car inner door module that is mass production-ready by injection molding. The module was developed in close cooperation between the company Brose and the TKV Foundation Partner SKL GmbH.

For the first time the Endowed Chair presented their carbon thin film laminates as PA6-FRP. Thirteen wafer-thin unidirectional laminate layers form with a 50% fibre volume content the only 1 mm thick composite. Together with the company M&A Dieterle in Ottenbach in Baden-Württemberg, the Torque-Fibre-Winding (TFW) technology was developed for the large-series production of textile-based thermoplastic prepregs.

Gemeinsam mit dem Unternehmen M&A Dieterle aus Ottenbach in Baden-Württemberg wurde die Torque-Fibre-Winding(TFW)-Technologie zur großserientauglichen Fertigung hierfür erforderlicher textilbasierter Thermoplast-Prepregs entwickelt.

The textile-reinforced foam cores with an extended properties profile in compression and bending elastic deformation behaviour under static and dynamic loads aroused equally keen interest among the international trade fair visitors.

The numerous discussions with an interested audience from the industry and economy as well as concrete coordination with cooperation and research partners, in order to strategically continue with the scientific and technical cooperation, confirm the practice and application-oriented research and development at the TU Chemnitz.

MERGE and the Endowed Chair TKV would like to hereby thank the foundation and research partners SKL GmbH Schwergewebekonfektion Lichtenstein, Oberlungwitz, the Technische Universität Chemnitz and the Saxon Economic Development Corporation for the successful cooperation in the preparation and implementation of our joint presentation at the JEC 2015 in Paris, as well as the German Federal Ministry of Education and Research (BMBF) and the German Research Foundation (DFG) for funding our research projects MERGE and PaFaTherm II. We look forward to the continuation of the scientific and technical cooperation, building on the commissions discussed at the JEC 2015, and also to a reunion at the JEC 2016.

Vivid transfer

On 10 February, 2015, scientists of the Federal Cluster of Excellence “Merge Technology for Multifunctional Lightweight Structures” (MERGE) presented their latest research results as part of the second meeting of the Industrial Advisory Board.

Prof. Dr. Arnold van Zyl, Rector of the TU Chemnitz and Prof. Dr. Dirk Landgrebe, Managing Director of the Fraunhofer Institute for Machine Tools and Forming Technology IWU welcomed the scientists of the Cluster and the numerous industry representatives with praising and motivating words, opening the event “MERGE Highlights” in the Virtual Reality Center of the Fraunhofer IWU. The keynote speeches highlighted the significance of innovative lightweight production technologies. The speakers were Prof. Dr. Axel Herrmann, CTC GmbH Stade, Airbus, on the topic of “Key technologies for high performance aircraft structures” and Prof. Dr. Thomas von Unwerth from the TU Chemnitz, on the subject "Novel pollution-free drive systems".

In addition to the lecture program of the second IAB meeting of the cluster, the focus was especially laid on the exhibition “MERGE Highlights”. The goal of the IAB meeting was to examine the latest research results and demonstrators and to develop a comprehensive overview of the actual needs of the economy. On five stations more than 50 scientists presented their work and preliminary research results focusing on: functional integration, in-line process and semi-finished technologies, structural integration and process technology and simulation. One stand was used solely for the Chemnitz-Car Concept, the MERGE system demonstrator, almost all sub-projects being involved in its development. Therefore, the student group Fortis Saxonia stood in focus with its developed lightweight vehicle Umicore EcoBee and the developed lightweight rim at MERGE.

The industry representatives praised the vivid presentation at the individual stations and the opportunity to get in touch with the staff and to discuss their research activities – an important step for the research transfer of the Cluster. University rector Prof. van Zyl, especially emphasized that MERGE is for many reasons a good example of vivid transfer: “It combines excellent scientists in many different research areas with innovative companies and secures our region, the Free State of Saxony and beyond the innovative drive that we need in international competition”.
