Automated systems use sophisticated sensors and imaging to detect defects such as voids, misaligned fibres, or surface irregularities. The result is a continuous strand of material that is lighter than steel yet stronger, a testament to engineering precision that enables the creation of products that push the boundaries of performance.

This stage tailors the material for the exact requirements of the final application, whether it’s a complex aerospace wing or a lightweight bicycle frame. A controlled oxidation process, either through plasma treatment or exposure to gases like ozone, etches the surface at a microscopic level.
Here, the temperature is ramped up to between 1,500°C and 2,000°C in a meticulously controlled inert atmosphere, typically involving nitrogen or argon. This synthetic polymer, derived from fossil fuels, is chosen for its molecular structure, which contains a high percentage of carbon atoms.

Alternatively, routes using coal or petroleum pitch exist, but PAN remains the dominant standard due to its uniformity and resulting mechanical properties. To solve this, the fibres undergo a surface treatment to increase their roughness and chemical activity.
