Figure 4

Intensity profile analysis of the soft X-ray images at the CF-matrix/adhesive interface. (a) The C, N, O, and F Kα SXM images at the CF-matrix/adhesive interface region. The intensity profile analysis around the interface was performed along the four straight lines with the circle, square, diamond, and triangle symbols. These symbols refer to those used in the intensity plot. (b) The segmented image of the CF-matrix/adhesive interface. The intensity profile analysis across the interface was performed along straight lines indicated with the circle, square, diamond, and triangle symbols. (c) The intensity profile for the C, N, O, and F Kα emissions at the CF-matrix/adhesive interface. The abscissa is the distance measured from the interface. The circle, square, diamond, and triangle data points correspond to the symbols in the segmented image.
