Composite materials are quite popular in the shipbuilding field, being used in military vessels mainly due to their non-magnetic properties and low specific weight. Other applications of composite materials in shipbuilding include engine-driven and sailing yachts, leisure boats, etc. The present paper deals with the numerical and experimental results obtained in the dynamic loading regime of composite material models. The most common and therefore taken as the subject of this paper is fiberglass-reinforced polyester (GRP). The paper focuses on numerical modellations of the impact phenomenon by means of FEM. The loadings of experimental models were performed with experimentally determined forces. The results of numerical modellations were experimentally verified on models of plane and curved plates with and without reinforcements, made of GRP. The devices used optical deformation measurement system ARAMIS HS and a stand where the trial specimen was mounted. The comparison of the numerical results and the experimental results evinced differences ranging between the standard deviations in such cases.
