Mechanically Reinforced Silkworm Silk Fiber by Hot Stretching

Figure 2

Mechanical properties of the as-obtained silk fibers and performance comparison of HSSFs with other materials: (a, b) Young’s modulus, tensile strength, toughness, and elongation at break of different silk fibers; (c) comparison of Young’s modulus and tensile strength of HSSFs with natural silk and regenerated silk. “This work” corresponds to 7.5%-S. “Silkworm silk” corresponds to Control-S. Spider silk 1 and 2 correspond to Araneus diadematus MA and viscid silk, respectively. Regenerated silk 1, 2, and 3 correspond to regenerated silkworm silk by wet spinning, regenerated silkworm silk by dry spinning, and regenerated natural or recombinant spider silk, respectively. Detailed data and their sources are shown in Table S4. (d) Comparison of Young’s modulus and tensile strength of HSSFs with natural and engineering materials. The Ashby plot was drawn according to two references (34, 35).
