摘要
PURPOSE: To increase the strength of a carbon fiber as a composite reinforcing material without damaging the carbon fiber, by subjecting to the fiber a treatment in which the fiber is allowed to pass through a plasma flame. ;CONSTITUTION: This method for increasing the strength of a carbon fiber comprises allowing the carbon fiber to pass through an intermediate temperature region of 350-600°C in the tip part of a plasma flame for 0.1-1.0sec or through a low temperature region of 100-350°C in the tip part for 0.1-1.5sec. When the treatment region is placed in the atmosphere, namely in the presence of 20-21% of oxygen gas, a large treatment effect is obtained.;COPYRIGHT: (C)1995,JPO
