Carbon fibres consisting mostly of synthetic graphite for which three-dimensional crystalline order is confirmed by X-ray diffraction.
Note:
@G02684@ fibres can be obtained by @G02692@ of carbon fibres if these consist mostly of @G02690@. If the h,k,l@D01711@ lines are difficult to recognize because they are of minor intensity, the mean interlayer spacing c/2 can be used as indication for the presence of a graphitic structure. The c/2 value of 0.34 nm is generally considered as an upper limit for @S06233@.
