Pre-oxidized fiber felt is produced by pre-oxidizing, crimping, cutting, and needle-punching polyacrylonitrile-based fibers. After carbonization, it becomes pre-oxidized fiber carbon felt, and after graphitization, it becomes pre-oxidized fiber graphite felt. Compared with PAN-based graphite felt, it offers advantages such as lower density, better flexibility, and reduced skin irritation.
