made from rayon (cellulose) precursor fibres.
Rayon-based carbon fibres have a more isotropic
structure than similarly heat-treated polyacrylonitrile (PAN
mesophase pitch (MPP)-based carbon fibres
Their Young's modulus
values are therefore drastically lower
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
