Term: rayon-based carbon fibres
https://doi.org/10.1351/goldbook.R05161

Definition:
Carbon fibres made from rayon (cellulose) precursor fibres.

Note: Rayon-based carbon fibres have a more @I03353@ structure than similarly heat-treated polyacrylonitrile (PAN)- or @M03851@. Their @M03966@ values are therefore drastically lower (100 GPa; tensile strength 100 MPa). Rayon-based carbon fibres can be transformed into anisotropic carbon fibres with high strength and @M03966@ values by hot-stretching treatment at temperatures of approximately 2800 K.
