Figure 5.

A, SEM image of RBSFs. B and C, the surface and cross-sectional structure of RBSFs. D, Polarized light microscopy image of RBSFs. E, Stress-strain curve of RBSFs with (red curve) and without (blue curve) weak fibrillar interface. The inserts are cross-sectional SEM images of the RBSFs after tensile fracture.
