Abstract
PURPOSE: To obtain graphite fibers of high strength and elasticity, by treating carbon fibers under specific controlled increasing and decreasing temperature conditions.
CONSTITUTION: Carbon fibers are heat-treated under such conditions as to give a ratio between the average temperature increasing rate from 1,000°C to the graphitizing maximum temperature and the average temperature decreasing rate from the graphitizing maximum temperature to 1,000°C of 1 or more, preferably 1.5W10, to give the aimed fibers. Carbon fibers formed by calcining acrylonitrile synthetic fibers are preferably used as the carbon fibers.
