Remote monitoring of a chemical vapor infiltration process by means of the FTIR system K300

The FT-IR system K300, primarily used for environmental monitoring by means of remote sensing techniques, has been modified in such a manner that it could be used for remote monitoring of a SiC chemical vapor infiltration process (CVI). This comprised hardware adaptations to a CVI reaction plant at DASA (MBB), as well as development of analytical methods. First measurements showed the good performance of the K300 system at the reactor. A lot of gaseous species could be detected and qualitatively analyzed (concentration changes).
