The growing demand for safer, lighter, and more sustainable structures has accelerated the development and validation of composite materials, which offer exceptional combinations of strength and lightweight. This thesis, a collaboration between Politecnico Di Torino, ITW Test and Measurement Italia s.r.l. - Instron CEAST division and The Leibniz-Institut für Verbundwerkstoffe GmbH, investigates a novel testing methodology for assessing Specific Energy Absorption (SEA) and introduces predictive models to evaluate the influence of geometry on crashworthiness performance. Motivated by the lack of a universal standard for the assessment of the SEA, this study investigates the performance of six different composite materials (CF-PA6, CF-PA66, CF-PC, GF-PP, GF-TEPEX, and CF-Epoxy) were tested under dynamic loading using an Instron 9450 drop tower and high-speed imaging.
