Dependence of mechanical properties on microfiber layout. Increased fiber fraction and alignment to the loading direction increased modulus (a, e). Increased fiber fraction and alignment also tended to increase the stress at which specimens displayed fiber network damage (b, f). Increased fiber fraction did not significantly enhance UTS, but alignment of fibers in the loading direction enhanced UTS compared to higher fiber angles (c, g). Resilience increased with increasing fiber fraction (d), and was also elevated when fibers were aligned or angled to the loading direction compared to the perpendicular layout (h). Significance indicated at the p<0.05 level, ns indicates non-significant differences, error bars represent standard deviations.
