Using Oxidation Ovens for Carbon Fiber Processing 机翻标题: 用氧化炉处理碳纤维

2020-02-10

The polyacrylonitrile precursor must be stabilized before the high temperature heat treatment that actually converts it to carbon fiber. The precursor is heated in air to between 200ºC and 300ºC for about 1 hour. Because of the temperature range, and especially because the process is exothermic, the heating is done with forced convection ovens. Convection allows both efficient heating of material as it enters the oven and removal of exothermic heat where the chemical reactions are most active.
