The micro-CT dataset was reconstructed using the ZEISS Scout-and-Scan Reconstructor software (Figure 1). 2D X-ray diffraction of Bombyx mori silk was carried out on a Bruker D8 Venture single-crystal

Figure 1 and Figure 2a show 3D reconstructions of the Bombyx mori silk fibers bundled together and their X-ray diffraction (XRD) pattern, respectively. The period d corresponds to the most pronounced peaks at the diffraction angle 2θ, given by Bragg’s
