Abstract
PURPOSE: To obtain carbon fibers, having high specific tensile strength and specific elasticity, and useful for industrial materials, etc., by flameproofing polyacrylonitrile fibers in an oxidizing atmosphere under specified conditions, and carbonizing the resultant fibers in an inert atmosphere in a furnace divided into plural parts at different maximum temperatures.
CONSTITUTION: Fibrous bundles or weblike materials formed from polyacrylonitrile or an acrylonitrile copolymer as a raw material are calcined in an oxidizing atmosphere at 200W400°C to give flameproofed fibers 1, which are then carbonized at a temperature in the range of 400W1,500°C in an inert atmosphere in a furnace divided into plural parts of a carbonizing furnace 2 at a temperature (T1) of the maximum ≤ 1,000°C, preferably 400W800°C, and a carbonizing furnace 3 at a temperature (T2) of the maximum ≤1,500°C, preferably 1,100W1,300°C, to afford the aimed carbon fibers. Preferably, the exhaust gas from the inert atmosphere of the carbonizing furnace 2 is expelled from a connecting part 9 through an exhaust port 8 at a temperature (T3) of 250°C or above.
