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).
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.
Microstructural Research and metallography
The group “Central Analytical Research and Metallography” is a central facility at the Institute of Materials Research. Characterization of materials with respect to microstructure, chemical and phase composition is carried out as a scientific and technical service. The group´s activities represent an important input for the correlation between material synthesis and material properties.
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).
Aerogels and aerogel composites
Aerogels are open porous, nanostructured materials manufactured by sol-gel technologies from water-rich solutions containing suitable chemical precursors. After their reaction a wet gel body containing nanosized particles being connected in3D like strings of pearls appear. Drying suitably conserves their solid skeleton and leaves materials with fascinating properties.
