“…For instance, the Octet Truss lattice with 0.02 wt.% of graphene content had an energy absorption per unit mass of 38.9 kJ/kg, which is nearly twice that of the 22 kJ/kg exhibited by the next best porous material, Balsa wood [55]. [56], Alporas [57], SiC-reinforced Al foam [58], Alulight [56], Al (5xxx) [59,60], Al (6xxx) [61,62], Al (7xxx) [60][61][62], non-3D-printed graphene-polymer composites [20,35,36,63], non-3D-printed carbon nanotube (CNT)polymer composites [64][65][66] and common porous core materials [55,67]. High strain rate tensile test results for Al alloys are plotted in (a) as well [68][69][70].…”
