| 摘要 |
The present invention relates to a method for producing carbon fiber which is produced, starting with a polyacrylonitrile (PAN)-based precursor, by undergoing a pre-oxidation process, an oxidation process, a pre-carbonization process, and a carbonization process. To this end, in the pre-carbonization and carbonization processes, the fiber introduced and then released out from a pre-carbonization furnace comprises two fiber layers on which fibers are arranged in parallel, wherein the two fiber layers are arranged in parallel. Furthermore, the pre-carbonized fiber released from the pre-carbonization furnace consists of two fiber layers, maintains a state of being arranged in parallel, and is introduced and released out from the carbonization furnace. |
