Fig. 3: Effects of strain rates on fracture surfaces of spider dragline silk fibers.

SEM images showing the fracture surfaces of the dragline silk fibers at RH43% under different strain rates: a 3.3 × 10−5 s−1, b 3.3 × 10−4 s−1, c 3.3 × 10−3 s−1, d 3.3 × 10−2 s−1, e 3.3 × 10−1 s−1, and f 3.3 s−1. Each scale bar denotes 5 µm. Arrows in (d) to (f) represent the broken fibrils in the fracture surface.
