Abstract
Impact fracture tests of laminated glass were performed using an instrumented drop weight testing apparatus. Different types of fracture mode were obtained by changing input energy and fracture absorbed energy was evaluated for each of the fracture modes. The experimental results clearly exhibited that large amount of energy absorbed through the deformation and fracture of the middle polymeric layer results in higher impact resistance of laminated glass than that of single glass. The result of strain measurement on the glass surfaces showed that the free glass layer fractured prior to the impact layer under this impact condition.
