The production and characterisation of low modulus carbon fibres is reported from a commercially available regenerated cellulose fibre (Cordenka™). The fibres were heat treated before graphitisation at a temperature of 200°C. Fibres were then further heat treated and graphitised at a temperature of 2000°C. Polarised Raman spectra of carbonised/graphitised fibres were recorded. The ratio of two Raman peaks located at ~1350cm <sup > -1 </sup > (D-band) and at ~1600cm <sup > -1 </sup > (2D band) - the I <inf > D </inf > /I <inf > G </inf > ratio - was used to follow the onset and development of the carbon/graphitic structure. It is shown, using tensile testing, that single carbon fibres processed at 2000°C have a modulus of ~70GPa and strain at break > 2 A Raman spectroscopic method that follows the shift in the position of the 2D band suggests a modulus of ~77GPa. Transmission Electron Microscope imaging of the fibres reveals a sub-structure containing aggregates of oriented concentric turbostratic carbon domains, some of which are reminiscent of carbon nanotubes. These relatively high strength fibres (1.5GPa) could be possible alternatives to E-glass fibres in low weight (~30% lighter than E-glass), high volume automotive and marine applications. It is also shown that these fibres can be converted in a woven precursor form to a carbon fibre fabric without the need to weave brittle filaments.
