Fractal structure of carbon fibers
Bogdanov S. G., Valiev E. Z., Pirogov A. N.
Small-angle neutron scattering by a cloth sample made of carbon fibers reveals that the fibers have a structure typical of bulk and surface fractals. The bulk fractal dimension D and the surface fractal dimension Ds are the same, D~DS~2J, within the experimental errors. These results can be explained in a natural way if it is assumed that the fibers of the cloth consist of fractal clusters with a dimension о D ~ 2.7 and a radius Rc ~ 200-400 A which are formed from carbon particles of о radius r0~ 18 A.
