Compressive and frictional properties of hydrogels and fiber-reinforced (FR) hydrogels. Equilibrium modulus for (a) hydrogels and (b) FR-hydrogels. Dynamic modulus at 1.0 Hz for (c) hydrogels and (d) FR-hydrogels. Coefficient of friction μeq for (e) hydrogels and (f) FR-hydrogels. Data presented as mean ± SEM. n = 5 per group. ^p < 0.05 over time, *p < 0.05 between groups.
