Fig.2 Typical repeated stretching tensile properties of spider Mas in air. The three silk samples were repeatedly stretched. The curves (a~d, e~h and i~l) are respectively from same silk samples, the curves (b, f and j) are stress-strain curves corresponding to the primitive force-displacement curves (a, e and i) on the testing software. The curves (d, h and l) are true stress-true strain curves corresponding to the force-displacement curves (c, g and k). One of double filaments was broken after a certain number of repeated stretching times
