Perforation impact behavior of Carbon Fiber Reinforced Plastics (CFRP) laminates was studied by comparing it with those of glass fiber reinforced plastics, aramid fiber reinforced plastics and 7075-T6 aluminum alloy. Using "TORAYCA" carbon tibers, M40, T300, T700S, T800H and T1000 and two types of epoxy resins having different cure temperatures, the effects of specimen thickness, tensile strength of unidirectional (UD) laminates, tensile strain of matrix and degree of surface treatment of carbon fibers on the perforation impact behavior were examined. The results showed that the impact resistance, the value of maximum load or the total absorbed energy, of CFRP was proportional to the strength of UD laminates, and was independent of the tensile strain of matrix and fracture toughness (G_<IC> and G_<IIC>) of UD laminates. It was also found that due to the lower inter facial bonding the impact resistance of CFRP increased when the degree of surface treatment decreased.
