Institute of Materials Research
Today technical systems have achieved such a high degree of complexity that further improvements can only be made by means of a multidisciplinary systems approach. Here the materials play a key role, as very often alone their availability is the decisive factor in the realization of the complete system. The investigation and development of new materials alone would only take us halfway. Nowadays manufacturability, availability and last but not least costs, are equally important when considering the technical usability and therefore also the commercial application and success of a material.
Research fields of the institut
High-temperature ceramic matrix composites for propulsion and thermal protection systems
From both economic and ecological viewpoints efficient and environment-friendly propulsion systems are extremely important for future civil and military aviation. An outstanding goal of research and development of DLR…
High Temperature and Functional Coatings
Coatings are used to protect materials and components against harmful attack of the environment. In the Institute of Materials Research both metallic and ceramic coatings are developed that protect metallic, ceramic, and composite materials…
Friction Stir Welding
Friction Stir Welding (FSW) is a simple, clean and innovative joining technology for light metals invented by TWI, England. Due to the high strength of FSW joints, it allows considerable weight savings in lightweight construction compared to conventional joining technologies.
Thermoelectric Materials and Systems
The department develops materials, contacting techniques and system related aspects for thermoelectric generators (TEG) and sensors for applications in air and space, in vehicles and energy facilities at medium and high temperatures (250-1000°C). Specialised measurement equipment, amongst this several in-house developments, is used in national and international cooperations to characterize nanostructured thermoelectric high-temperature materials of novel substance classes with improved application properties and for tests of thermoelectric conversion modules. Uniquely within Germany the techniques available at DLR resemble a closed process chain from powder production to modules and their test in one location.
Mechanics of Materials and Microstructures
In aircraft and spacecraft structures and their engines a multiplicity of different material are used to meet requirements for optimal technical safety and economic efficiency ...
Experimental and numerical Methods
The demand for shorter development times for new components and technical units requires accelerated and accurate determination of material properties. By combining experimental and numerical methods it is possible to reduce the number of time consuming experiments without loss of accuracy and reliability of the obtained data.
Hybrid Material Systems
Any material is marked by its specific properties and advantages. Due to the increasing complexity und manifold requirements for components the choice of a material is often related to penalties under certain conditions. To avoid this drawback an intelligent combination of different materials to a hybrid material system can be preferred.
Titanium aluminides are intermetallic alloys with titanium and aluminium as mean alloying elements. Titanium aluminides are promising materials for high temperature and structural applications of the future. Due to their low density along with an excellent high temperature strength these materials are predestine for usage in stationary and aeronautic gas turbines as well as for valves and turbo chargers in cars.
Mechanical Testing of Materials
Mechanical Testing of Materials offers mechanical material characterization as scientific-technical service for all departments of the institute as well as for external customers. Mechanical material tests are performed under various loads, which can be uniaxial but also biaxial. Measurements are possible in air, vacuum, and corrosive environments at varying temperature ranges (-196° up to +1,400°C).
Aerogele und Aerogelverbundwerkstoffe
Aerogele sind offenporige, nanostrukturierte Werkstoffe, die aus wässrigen Lösungen durch Gelation (Sol-Gel-Verfahren) und geeignete Trocknungsverfahren gewonnen werden. Übrig bleiben Festkörper mit faszinierenden Eigenschaften. Sie haben eine geringe Dichte, eine hohe innere Oberfläche, eine extrem niedrige Wärmeleitfähigkeit sowie eine hohe Schallabsorption. Sie können spröde wie Keramik oder flexibel und elastisch wie Gummi sein. Ihre Einsatztemperaturen gehen je nach Ausgangstoffen von -200°C bis 1400°C.
Microstructure Analysis and Metallography
Characterisation of materials with respect to microstructure, chemical and phase composition is carried out as a scientific and technical service. These works deliver an essential contribution to the understanding of the interrelationship between materials synthesis and properties. The interpretation of the microstructure and analytic data is carried out in close collaboration whit the other departments and work groups of our institute.
