A method of producing carbon fibre includes the steps of providing a solution of a coal-derived material in a solvent, typically dimethylformamide, adding polyethylene oxide having a molecular weight of at least 3 x 10<6> daltons to the solution to provide a spinning solution, spinning the spinning solution into a fibre and causing the fibre to gel, typically by contacting it with a gelling solvent. The coal-derived material will have a composition, free of solvent, of 70 to 91 percent by mass of carbon, 2 to 6 percent by mass of hydrogen and 3 to 20 percent by mass of oxygen.
