This study delves into the effect of repeated low-velocity impacts on the residual tensile strength of composite laminates reinforced with E-glass/epoxy woven fabrics. The specimens underwent a series of low-velocity impacts, each delivering a constant energy of 4 J. Various parameters, such as maximum impact load, displacement, contact time, and absorbed energy, were examined. The residual tensile strength was subsequently analysed for each impact and compared to control specimens that experienced no impact. The results highlighted a significant decrease in residual tensile strength after the initial impact, whereas subsequent impacts exhibited a diminished effect until the puncture of the specimens occurred.
