Impact characteristics of laminated composites

In this study, the influence of size and location of embedded delamination on impact behavior of laminated composite is investigated, experimentally. The fiber-reinforced composite materials used in this study was manufactured at Composite Laboratory in Dokuz Eylül University, and was prepared by cutting defined size for tests in Izoreel Firm, and they consist of 12 plies lamine is designed as defined orientation.The specimens were produced as for with and without delamination by vacuum assisted resin infusion molding method (VARIM). As matrix materials, the mixture of Durateks DT E 1000 epoxy and Durateks DT S 1105 hardener resin; and as reinforcement materials, unidirectional E-glass fabric were used. The experiments were performed by using Ceast-Fractovis Plus impact test machine. As a result of the experiments, the location of delamination on the impact behavior is seen to be more effective than the size of delamination.
