High-Tech for Saxon Lightweight Construction Research

Lightweight Technologies laboratory building at the MERGE Research Centre at Chemnitz University of Technology completed - Free State of Saxony invested around 14.5 million euros, most of which came from the European Regional Development Fund (ERDF)

The new laboratory building for the Central Institution MERGE at Chemnitz University of Technology has started its research operation. The production of novel energy- and resource-saving materials is investigated and analyzed on a total of 1,486 square meters. These materials are used, among other things, in the mobility sector and in the aerospace industry. For this purpose, a modern new laboratory building has been under construction by the state-owned Sächsisches Immobilien- und Baumanagement (SIB - 'Saxon Property and Construction Management') since August 2018. After the structural handover to Chemnitz University of Technology in October 2020 and the subsequent installation work by the university, research can now begin. In addition to highly specialized laboratory space, the new building also offers office, teaching, and meeting rooms.

"With MERGE, the Free State of Saxony is expanding its international role in lightweight construction research. For scientists from all over the world, we are creating the best conditions in Chemnitz for research and creative exchange. Chemnitz University of Technology receives another attractive location that enriches the city as a whole," said Saxony's Minister of Finance Hartmut Vorjohann. Science Minister Sebastian Gemkow adds: "The new building for MERGE will significantly strengthen lightweight construction research in Saxony and thus the Lightweight Construction Alliance Saxony. At the Chemnitz site, new opportunities are opening up for further advanced research at the highest level. This will benefit not only the participating scientists but also other partners such as those from industry. I am glad that we can offer the necessary framework conditions for consistent further development. With many future fields of application, lightweight construction is central to the economic development of the Free State."

Lightweight construction technologies continue to be among the technologies of the future for achieving sustainable reductions in CO2 in all areas of production. With maximum resource efficiency, the saving of weight, material and energy, while at the same time safeguarding or even improving the functionality and also performance of components, the advantages are clear. Lightweight construction can thus make a decisive contribution to achieving the German government's climate and sustainability goals. By combining digital process tools, innovative materials and manufacturing processes, new functionally integrated components can be developed. The use and application of bio-based materials in combination with bionically inspired designs opens new avenues for resource-efficient products and technologies in the future.

"In addition to the existing research hall, the new laboratory building is another building block underpinning the leading position of lightweight construction research at Chemnitz University of Technology and thus at the same time strengthening our core competency of resource-efficient production and lightweight structures. We would like to express our sincere thanks to the Free State of Saxony and the European Union for this important investment in Chemnitz as a center of science and industry," says Prof. Dr. Gerd Strohmeier, President of Chemnitz University of Technology.

"With the commissioning of the second construction phase, the MERGE laboratory building, the integration of many decentralized laboratory facilities and thus significantly improved and faster work in the numerous research projects has become possible. In particular, the equipment in the area of testing technology, with the help of which, for example, extended material and load tests are carried out, is now entering a new league," says Prof. Dr. Lothar Kroll, Coordinator of the Central Institution MERGE and Head of the Department of Lightweight Structures and Polymer Technology at Chemnitz University of Technology. "With the help of this technology, highly filled plastic compounds for new fuel cell applications are currently being investigated, for example. Also in the context of large-scale projects such as thermoprePlus, SmartERZ, InnoCarb Energy, and many SME-supported projects under the Central Innovation Programme ZIM, the new infrastructure will significantly support us in achieving the best possible research results, which are of enormous importance, especially for SMEs," says Kroll.

The new laboratory building extends the hall complex of the MERGE Research Centre, in which research has already been carried out since August 2015. The new building is directly adjacent to its south facade. Both buildings are connected to each other on the first floor and the second floor. There is also the possibility of adding an office building to the overall complex.

The total construction costs of the new laboratory building are around 14.5 million euros, which was financed by funds from the European Regional Development Fund (ERDF) and tax revenues on the basis of the budget approved by the members of the Saxon state parliament.

Background: MERGE - Technologies for Multifunctional Lightweight Structures

With the Federal Cluster of Excellence MERGE - Technologies for Multifunctional Lightweight Structures, Chemnitz University of Technology was among the winners of the Federal Excellence Initiative. MERGE was funded as a Federal Cluster of Excellence by the German Research Foundation (DFG) from 2012 to 2019. In the project, which is unique in Germany, around 100 scientists worked on bringing together previously separate manufacturing processes in the processing of different material groups such as textiles, plastics, and metals. MERGE researchers are now working toward reapplying for a place as a Federal Cluster of Excellence in the next strategy round in 2025. Additional information:
