Abstract (en)

[origin: EP0154175A2] Carbon fiber precursors are stabilized regarding their mechanical properties by conducting the stabilization procedure in at least two steps, the first at a temperature at which the maximum plasticity of the polymer is attained while stretching the fiber 10-50% and the second at 200 DEG -300 DEG C, but higher than the first.
