This work proposes the study of the influence of scaled down ply layout techniques applied in a laminated composite structure submitted to fast dynamics. By its wide-ranging advantages, scale reduction represents a significant stake for engineers. An experimental campaign is carried out on an omega-shaped structure. The energies absorbed, as well as the efforts applied in the composite structure are then compared between the scale 1 prototype with the various models established (scales 1/2 and 1/4). The conclusions generated are numerous. Firstly, in this geometrical configuration, dynamic loading does not have the same effects on the results and, secondly, the relations of similitude used seem to be able to give some solutions, if the same ruin damage modes appear.
