The polymer is dissolved in a solvent to form a viscous solution, which is then forced through a spinneret to create long, continuous filaments. Heat causes the fibres to oxidize, creating cross-links that prevent the strands from melting when exposed to extreme heat later.

To solve this, the fibres undergo a surface treatment to increase their roughness and chemical activity. 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 high-performance material, renowned for its exceptional strength-to-weight ratio, begins not as a fibre but as a precursor polymer. This polymer coating acts as a lubricant for handling, protects the delicate fibres from damage, and further enhances the interface with the composite resin.

The finished yarns are then wound onto bobbins, ready for conversion into specific forms like tow, fabric, or braided textiles. Stabilization: The Critical Transformation Before the fibres can be carbonized, they undergo a crucial thermal treatment in air known as stabilization.
