Polymer coatings applied via methods such as electron-induced polymerisation, polymer surface media, and surface coating introduce a thin polymer film onto the carbon fibre surface, thereby achieving compatibility with the matrix resin.   Plasma constitutes a collective of matter comprising a sufficient quantity of positively and negatively charged particles with […]

Carbon fiber, as an advanced material characterised by high strength and modulus, typically requires composite processing with other matrix materials to form composite structures for practical application. Due to the high-temperature treatment exceeding 1300°C that carbon fibre undergoes, comprising over 90% carbon content with minimal surface active functional groups, it

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
