Title:

CARBON FIBER MANUFACTURING DEVICE AND CARBON FIBER MANUFACTURING METHOD

Document Type and Number:

WIPO Patent Application WO/2015/152019

Kind Code:

A1

Abstract:

The problem of the present invention is to provide a carbon fiber manufacturing device in which fiber to be carbonized is irradiated with microwaves and thereby heated, wherein the carbon fiber manufacturing device is compact and capable of performing carbonization at atmospheric pressure without requiring an electromagnetic wave absorber or other additives or preliminary carbonization through external heating. This carbon fiber manufacturing device (200) includes: a cylindrical furnace (27) comprising a cylindrical waveguide in which one end is closed, a fiber outlet (27b) being formed in the one end of the cylindrical waveguide and a fiber inlet (27a) being formed in the other end of the cylindrical waveguide; a microwave oscillator (21) for introducing microwaves into the cylindrical furnace (27); and a connection waveguide (22) having one end connected to the microwave oscillator (21) side and the other end connected to one end of the cylindrical furnace (27).
