Method of spinning pitch-based carbon fibers.

摘要

A method of spinning a pitch precursor material to produce a continuous pitch-base carbon fiber (10), in which the precursor material is spun through capillaries (11) of a spinnerette (12) such that a fiber carrot (13) formed during spinning will exhibit a viscosity of at least 230 Pa.s at or near a point of spin reversal (17) of the fiber carrot (13).
