& 3 E35 carbon fiber. a) Lattice fringes TEM mode showing the carbon layers in a longitudinal section of the fiber. This fiber is much less heat-treated than the P55 as asserted by the waving of the layers, the medium lc stacking order (less than 10 layers in coherence) and the lack of second order (004) in the SAD pattern. b) 002 darkfield mode showing a complete domain of this fibre at lower magnification: long range alignement is not perfect along the axis.
