Fig. 2.

(A) Stress–strain curves of different composites EA (λ₀) made from the same filler network. The value of λ₀ is shown in the labels attached to each curve. The color corresponds to the number of polymerization steps: black, one; red, two; blue, three; and green, four. $\dot{\lambda }$ = 0.021 s⁻¹ for all tests. (B) Young’s modulus as a function of the degree of prestretching λ₀ of the filler network. (C) Evolution of J_m and λ_h obtained from the best fit to the Gent model as a function of λ₀.
