3D architecture of the impact surface and impact region revealed by nano-CT characterization. (a) Highly interpenetrated 3D structure consisting of three main segments: mineral nanoparticle aggregation, chitin fiber scaffold and pore canal network. (b) 3D model of pore canal network. (c)–(d) Slices of CT scan acquired from perpendicular projections (white regions represent mineral particles, gray regions represent chitin fiber bundles and black regions represent pore canals.). (e) 3D rendering of interest volume. The distributions of pore canals (e-ii) and minerals are highly correlated (e-iii) shown in colored CT slices, with (e-i) showing a representation of the mineral particle distribution; (e-iv) shows the interlocking structural design of mineral particles and fiber bundles in the impact surface and impact region.
