Figure 6
Color-coded spheres indicate two main orientations within the layered carbon-fiber-in-PEEK sample: (a) side view and (b) front view. (c) RSM error curves correspond to different projection numbers and sampling strategies. The yellow star indicates the full-dataset reconstruction. (d)–(f) One representative reconstructed slice from the purple-pink part, where color indicates the mean value and the cylinder orientation represents the main direction; (d) from full 423 projections as reference, (e) from 60 DUS projections, in which key orientation features are preserved, and (f) from the first 60 SNUS projections, showing more obvious difference.
