For the development of components made of fibre-reinforced ceramics, the DLR Institute of Structures and Design in Stuttgart has several furnaces for high-temperature processes, in addition to modern facilities for pre-body production. The laboratory furnaces are used for the development and production of ceramic matrix composites (CMCs), in particular, of the material classes C/C, C/C-SiC and SiC/SiC.
High-performance furnace for the development of new materials
Research focuses on liquid metal infiltration (RMI), particularly liquid silicon infiltration (LSI), as well as polymer infiltration and pyrolysis (PIP). The performance spectrum of the furnace systems ranges from small laboratory-scale test furnaces for preliminary tests for materials development up to large systems for the production of full-scale CMC components. With a cube-shaped combustion chamber of approx. 850 mm edge length each and a maximum temperature of 2000°C, the furnace systems for pyrolysis and siliconization ("OPUS 900") can cover a wide range of CMC development. A process monitoring and documentation system enables automatic operation around the clock, as well as comprehensive quality assurance.
