Abstract Strong and tough mechanical metamaterials are highly demanded in engineering application. Nature
inspired dual-phase metamaterial composites was developed and examined, by employing architectured
lattice materials with different mechanical properties respectively as the constituent matrix and
reinforcement phases. Then, the reinforcement phase was incorporated into the matrix phase with specific
patterning. The composite metamaterials were simply fabricated using additive manufacturing. From quasistatic compression tests, the strength and toughness could be simultaneously enhanced after the addition
of reinforcement phase grains. Through simulation modeling, effects of dual-phase distribution, elementary
architecture, parent material and defects on mechanical properties of dual-phase mechanical metamaterials
were investigated.… More >
