In the early 1960s they were highlighted as a “Rider of a New Industrial Revolution” and as an initiator of a new “Carbon Age”. In Europe, the SIGRI Elektrographit GmbH, Meitingen / Germany started in the late 60s one of the first industrial pilot plant in the world.
Since that, the most important established precursor materials is polyacrylonitrile. The chemical conversion of the precursor into an unmeltable ladder structure with following elimination of nitrogen atoms and the formation of graphitic carbon layers characterizes the production process. These conversion reactions are very complex and up to now not fully understood. Some of them are extremely exothermic what means a challenge for the process control.
The actual technology for CF processing, concerning the chemical and physical processes as well as the parameters defines the key elements forming high-strength carbon-carbon bonds within the fiber structure.
It is obvious that alternative precursor material will have similar complexity when creating carbon fibers.
