Carbon fibres obtained by carbonization of isotropic pitch fibres after these have been stabilized (i.e. made non-fusible).
During fabrication of @I03353@ @P04678@ no means (neither mechanical nor chemical) are applied to achieve preferred orientation of the polyaromatic molecules in the fibre direction. They belong to the @C00836@ (low modulus), and because of the relatively low values of strength and @M03966@ this @P04678@ type is not used for high-performance reinforcement purposes.
