Carbonization of Polyacrylonitrile(PAN)

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 […]

Pre-oxidation Treatment of PAN Precursor

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

Industrial Grade Carbon Fibre Fabric

What is industrial-grade carbon fibre? Industrial-grade carbon fibre is a concept relative to ‘aerospace-grade’, referring to cost-effective carbon fibre products primarily used in civil and industrial applications. Its core characteristic lies in employing large-tow specifications (such as 24K and above), significantly reducing costs through mass production. While its mechanical
