rayon-based carbon fibres

https://doi.org/10.1351/goldbook.R05161
Carbon fibres
made from rayon (cellulose) precursor fibres.
Note:
Rayon-based carbon fibres have a more
isotropic
structure than similarly heat-treated polyacrylonitrile (PAN)- or
mesophase pitch (MPP)-based carbon fibres
. Their
Young's modulus
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
Young's modulus
values by hot-stretching treatment at temperatures of approximately 2800 K.
