Abstract
Disclosed is a method for making a carbon fibre from a paper product. The method includes preparing a cellulose-based fibre by crushing the paper product, dissolving the crushed material obtained in an aqueous phosphoric acid solution to form a spinning solution, and forming a cellulose-based continuous fibre by use of a solvent spinning process. The cellulose fibre formed in this way is subjected to carbonisation treatment in order to form a carbon fibre.
