Poisson's ratio (NPR) structure with high specific strength, high specific stiffness, high impact resistance and other characteristics is widely used in aerospace, medical equipment, transportation, shipping, sports, and other fields. Double arrowhead triangular with NPR effect has been proposed and designed. Poisson's ratio and low-velocity impact resistance of double arrowhead triangular structure have been calculated by numerical theory and finite element analysis. The impact failure mode, the impact velocity history curves, and the distribution of the first principal stress of double arrowhead triangular board structure have been analyzed. Also, the mechanism of low-velocity impact resistance of the double arrowhead triangular board structure and the influence of angle parameters on impact performance have been revealed. The results show that when =20°and =50°, the Poisson's ratio of double arrowhead triangular structure is -2.1, and the low-velocity impact resistance of double arrowhead triangular board structure is the strongest. Our findings here broaden the engineering applications of double arrowhead triangular structure and NPR structures.
