【Abstract】 High modulus PAN based carbon fiber was produced continuously by high frequency induction heating. Carbon fiber can be heated to 2?800?℃ in 2?s and retained at that temperature for 10?s with a speed of 400?m/h using this apparatus. The mechanical properties of the graphite fibers produced are comparable with those of Toray M40, showing that this method have good prospects.更多还原
