To further enhance the mechanical properties of carbon fibre, particularly its modulus, and to meet the requirements of specialised applications, it is often necessary to subject the carbon fibre to high-temperature treatment, namely graphitization. Graphitization is typically conducted within high-temperature furnaces under inert gas protection, subjecting the carbon fibres to […]

Carbonization is a crucial process in which PAN fibres undergo a transformation from organic polymers to inorganic carbon structures. The carbonization of PAN fibres typically comprises two stages: low-temperature carbonisation and high-temperature carbonisation. The low-temperature carbonisation process generally occurs at temperatures ranging from 300 to 1000°C, while high-temperature carbonisation typically

The pre-oxidation process of PAN precursor filaments represents a pivotal stage in carbon fibre production, facilitating the transition from organic to inorganic structures. From a structural transformation perspective, it may also be termed a thermal stabilisation process. Typically conducted in an air atmosphere, this involves prolonged heat treatment of PAN
