Abstract

Disclosed is a process for manufacturing carbon fiber in which a polyacrylonitrile polymer in the form of a multitude of filaments is heated in an atmosphere that is substantially free of oxygen to form a thermally stabilized carbon fiber precursor in an oxygen-containing atmosphere to form a stabilized and oxidized precursor and then the thermally-stabilized precursor is heated in an oxygen-containing atmosphere to oxidize the precursor, which is then conventionally carbonized in an atmosphere substantially free of oxygen.
