The aim of this work is to study the dynamic behavior of glass fiber reinforced polyester composites when they are subjected to repeated impact loads. Tests were carried out using a repeated impact-testing device, which was modified using data acquisition systems, and calibrated using strain gauges. Results were reported in terms of dynamic deflection, impact fatigue life and delamination width. Results showed that impact force had significant effect on dynamic deflection, and that the major failure mechanisms were delamination, matrix cracks and fiber pullout
