Abstract In this paper, a split Hopkinson pressure bar (SHPB) was used to investigate the dynamic impact mechanical
behavior of sisal fiber-reinforced cement-based composites (SFRCCs), and the microscopic damage evolution
of the composites was analyzed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDS). The results show that the addition of sisal fibers improves the impact resistance of cement-based composite materials. Compared with ordinary cement-based composites (OCCs), the SFRCCs demonstrate higher
post-peak strength, ductility, and energy absorption capacity with higher fiber content. Moreover, the SFRCCs
are strain rate sensitive materials, and their peak stress, ultimate strain, and energy integrals all… More >
