The science and technology of carbon fiber production has been well documented in numerous papers, reviews and textbooks [[1], [2], [3]]. About 90% of carbon fibers are based on polyacrylonitrile (PAN), while a small amount is based on rayon or petroleum pitch, notably some higher modulus grades.
The situation is different in the carbonization process. The higher carbonization temperatures in PAN-based carbon fiber production result in higher energy cost and capital expenditures for the carbonization furnaces. Furthermore, the exhaust gases of the carbonization are treated differently in the two carbon fiber production processes.
Since C-fiber production is very energy-intensive, it is no longer possible to talk about materials today without addressing their recycling and carbon footprint in the lifecycle analysis.
