Abstract
Four pitch-based carbon fibres (laboratory made): radial with wedge (i1), radial (i2), statistically radial (i3), and concentric (i4) were prepared from heterogeneous pitch (mixture of a gel and an isotropic phase). Fibers i1 to i4 have the same nanotexture (inheritance of the gel). When as-spun or oxidized, it is the association of a major component with channels. During carbonization, the two components coalesce into a zig-zag nanotexture. Fibrils of nongraphitizing carbon are the inheritance of the isotropic pitch. i1 has a perfect radial orientation of the zig-zag. They are bent in periphery in i2. In i3 there is only a statistical tendency to be radial. A certain order is recovered in i4 inside which the zig-zags are concentric.
