In this paper, we perform the behavior of aeronautics composite material subjected to a low energy impact. The proposed study considers the dynamic impact between a small piece of granular material and a large body of composite material. The principal aim is to simulate the impact of runway debris thrown up by the landing gear against an airplane structure. In the simulation, a CFRP composite panel impacted by granular particles at low speed is considered. The finite element analysis, initially on the macroscale and subsequently on the micro-scale, shows the delamination inside the composite according to the experimental results.
