WebApr 15, 2009 · Annealing treatment at more than 500 °C in an inert atmosphere such as an N 2 atmosphere or a vacuum (10 −5 Torr) was also found to be effective; however, annealing does not affect samples obtained in air or in the absence of carbon. WebCarbonization (high temperature phase): the stabilized fibers are passed through zones of increasing temperature to around 1500 °C in an inert atmosphere, usually nitrogen. This is the first step in which the carbon fiber structure and associated properties are developed. 3.
