“…The stress transfer from the matrix to the fibers is achieved through the shear stress (or rather, the bond) at the fiber/matrix interface. The role of fibers in the composite is to delay the occurrence of cracks and restrain their propagation through fiber bonding, debonding and pullout processes, thus greatly improving the mechanical properties such as the bearing capacity, energy dissipation capacity (or rather, ductility), toughness and impact resistance (Aslani and Nejadi, 2012;Cunha et al, 2010;Lee et al, 2010;Moradi et al, 2020;Xu et al, 2011Xu et al, , 2012Yang et al, 2020;Zacharda et al, 2017;Zhang et al 2013). This is the so-called crack bridging effect, the main mechanism of fiber reinforcement.…”
