摘要： The invention relates to an improved process for forming a stabilised precursor that is suitable for the manufacture of carbon materials, such as carbon fibre. The process can convert a precursor comprising polyacrylonitrile into a stabilised precursor with greater efficiency. The invention also relates to a process for preparing a carbon fibre that utilises the stabilised precursor.

摘要： The present invention relates to a reactor for pre-stabilising a precursor for a carbon-based material, the reactor comprising: a reaction chamber adapted to pre-stabilise the precursor in a substantially oxygen-free atmosphere as the precursor is passed through the reaction chamber under a predetermined tension; an inlet for allowing the precursor to enter the reaction chamber; an outlet for allowing the precursor to exit the reaction chamber; and a gas delivery system for delivering substantially oxygen-free gas to the reaction chamber, the gas delivery system comprising: a gas seal assembly for sealing the reaction chamber to provide the substantially oxygen-free atmosphere therein and for limiting incidental gas flow out of the reactor through the inlet and the outlet; and a forced gas flow assembly for providing a flow of heated substantially oxygen-free gas in the reaction chamber to heat the precursor in the substantially oxygen-free atmosphere.
