Two geometries for scanning SAXS and WAXS. (a) Fibre geometry: the beam is perpendicular to the fibre axis. (b) On-axis geometry: the beam is parallel to the fibre axis. (c) SAXS composite image from two-dimensional scanning of a thin slice of a carbon fibre in on-axis geometry. The anisotropy of the SAXS signal is directly related to the cross-sectional orientation of the shelf-shaped nanopores. (d) Cross-sectional pore orientation (direction of black lines) overlayed on the SEM image of the fracture surface of a MPP fibre.
