Title: Method for producing carbonized fiber
Inventor: WANG ZHI-YONG
IPC: D06M10/02
Filed: 2017-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a carbonized fiber.SOLUTION: A method for producing a carbonized fiber includes: subjecting a carbonized fiber precursor fiber bundle to a high-temperature carbonization process to form a carbonized fiber; then subjecting the carbonized fiber to plasma treatment to form a relatively roughened plasma modified structure on a surface of the carbonized fiber; and finally covering the surface of the carbonized fiber with a resin oil agent to obtain a carbonized fiber having the resin oil agent thereon. The surface of the carbonized fiber is roughened through the plasma surface treatment and simultaneously functional groups of the surface can be increased, a good interface bond between the carbonized fiber and the resin oil agent can be achieved, and accordingly a carbonized fiber having a relatively stronger structure and reliability is obtained, and a production facility cost and man hours of the carbonized fiber can be effectively reduced.SELECTED DRAWING: Figure 1
