Stabilization and carbonisation conditions are the main factors influencing the properties of carbon fibres manufactured from polyacrylonitrile (PAN) fibres. In this report, low-cost commercial PAN fibres (textile grade) were used as precursors and the effects of the two mentioned factors on the tensile strength of carbon fibres were evaluated. By using the well-known Plackett-Burman screening method in the design of experiments, the best conditions to produce an economical product were determined. The results showed that this method can improve carbon fibre tensile strength by more than 15.7%.
