Experimental drop weight impact tests have been performed to investigate the impact behaviour of small-scale clamped laminated plates struck laterally by a mass with a spherical indenter. Four thin specimens and four thick specimens were tested in order to study the influence of the impact velocity and the plate thickness. The tests are conducted on a fully instrumented falling weight machine. The experimental results show that the plate thickness and the material properties strongly affect the impact response of plates. In the experiments, multiple damage modes are observed and the damage mechanisms vary from delamination to perforation when the incident energy increases. The results are compared with similar published tests in order to investigate the influence of plate thickness on the impact behaviour of specimens. Moreover, numerical simulations are performed to analyse the structural response of the impacted plates before fracture, obtaining good agreements when comparing with the experimental results.
