Abstract
PURPOSE: The flame-resisting treatment and carbonization treatment of acrylonitrile fiber are effected subsequently in an oxidative atmosphere and an inert atmosphere at lower temperature than a specific one to produce the titled fiber with increased elongation as well as improved strength and elasticity and high impact strength.
CONSTITUTION: Acrylonitrile fiber is subjected to the flame-resisting treatment in an oxidative atmosphere, e.g., in the air, at 200W300°C to make the density of the fiber 1.30W1.45g/cm3, preferably 1.32W1.42g/cm3. Then, the carbonization treatment is effected in an inert atmosphere under elongation, preferably 100W130% elongation so that the nitrogen content becomes 10W20wt% to produce high- strength and high-elongation carbon fiber of higher than 200kg/mm2 strength, 5W 20ton/mm2 elasticity and more than 1.5% elongation.
EFFECT: Since the carbonization furnace is required to resist a temperature lower than 1,000°C, the facilities become inexpensive and the production cost becomes low.
