Abstract
Production of carbon fibre from a multifilament tow of organic precursor fibre, by heat treatment in an oxygen containing atmosphere and subsequent carbonization optionally followed by graphitization, the tow being given a twist between the oxygen treatment and carbonization, which twist is made permanent by the carbonization and maintains the fibres within the tow during the carbonization and subsequent handling.
