In this study, β-Ti3Au lattice structure was proposed for the first time in the literature as a filling material to increase the energy absorption performance of thin-walled tubes. In this context, the energy absorption performances of conventional lattice structure (i.e., BCC and FCC) filled thin-walled tubes and proposed novel β-Ti3Au lattice structure filled thin-walled tubes with proposed were compared experimentally. BCC hybrid, FCC hybrid and β-Ti3Au hybrid structures produced by additive manufacturing technology using PA2200 powder were crushed and evaluated by considering various crashworthiness criteria such as EA and SEA. The results showed that the β-Ti3Au hybrid structures are better crashworthiness performance than that of traditional filling BCC and FCC lattice structure filled thin-walled tubes. In particular, the β-Ti3Au hybrid structure has 18.17% and 19.39% higher EA values than BCC hybrid and FCC hybrid, respectively. These values are 16.50% and 15.66% for SEA values, respectively. As a result, the current investigation showed that the suggested β-Ti3Au lattice structures as a filler material can be a significant alternative for applications where energy absorption performance is critical.
