Fig. 3: Toughening mechanism of FRCI.
From: Tough fiber-reinforced composite ionogels with crack resistance surpassing metals
a Relationship between the tearing toughness of the composites and the tearing toughness of the polymer matrices. b XPS O 1s spectra of the FRCI, ionogel, and CF fabric. c Binding energies between components in FRCI and PDMS/CF. d Dissipated energy and damping capacity of the ionogel at different strains. e, f Stress nephograms of the FRCI (e) and PDMS/CF (f) during the fracture process. Data in (a) are reported as their means ± SDs from n = 3 independent samples.
