Abstract (en)
[origin: EP0098025A2] A polyacrylonitrile-based carbon fiber having both high Young's modulus and high tensile strength is disclosed along with a method for producing the same. The fiber is produced by winding an infusibilized polyacrylonitrile fiber onto a stable bobbin, carbonizing the fiber on the bobbin and subjecting the carbonized fiber to a heat treatment in a threadline operation.
