Abstract: In this study, continuous E-glass fiber reinforced composites have been manufactured with two types of resin, polypropylene (thermoplastic) and epoxy (thermoset), and they have been subjected to the low velocity impact and compression test after impact and effect of resin type on the impact damage response of composite laminates were investigated. Impact energies were chosen as 30 J, 40 J, 50 J and 60 J, and the residual compressive strength was obtained by compression after impact test. The results show that the damage area, dent depth, post-impact compression failure mechanism and residual compressive strength values of glass fiber reinforced polypropylene and epoxy composite laminates are different due to the different interlaminar fracture toughness and toughness of the resin matrix. The type of matrix material has a crucial effect on the low velocity impact damage of composites.
