Lab-scale continuous furnace for low-temperature fiber carbonization
High-temperature (HT) carbonization is applied to achieve the end product‘s target mechanical properties, in particular to increase the stiffness of carbon fibers. As part of this process step the fibers are heated up to 1800 °C under inert atmosphere in the specially developed continuous furnace c.HT Carbon.
During the LT (low-temperature) and HT carbonization steps the majority of VOCs, contaminants and exhaust gases are released, what makes the handling and abatement of off-gases one of the major challenges. This is solved by the use of a heated exhaust channel combined with condensate separation and differential pressure control.
The system provides data storage for recipes and control-related parameters as well as an Ethernet interface for external PC or remote access. Furthermore, it includes automated data collection and analysis via user interface.
