Abstract In this study, the real 3D model of the feather shaft that is composed of medulla and cortex is characterized by X-ray
computer tomography, and the structural features are quantitatively analyzed. Compression and tensile tests are
conducted to evaluate the mechanical performance of the feather shaft and cortex at different regions. The analysis
of the 3D model shows that the medulla accounts for ∼70% of the shaft volume and exhibits a closed-cell foam-like
structure, with a porosity of 59%. The cells in the medulla show dodecahedron and decahedron morphology and
have an equivalent diameter of… More >
