The invention discloses a bionic biphase mechanical metamaterial and a college student formula car crash box, and the bionic biphase mechanical metamaterial comprises a soft-phase unit cell microstructure and a hard-phase unit cell microstructure, the hard-phase unit cell microstructures and the soft-phase unit cell microstructures are assembled into representative volume unit cells according to a two-phase specific continuous arrangement form by adopting a toughening mechanism in a biological material. The bionic biphase mechanical metamaterial has the advantages of low relative density, light weight, excellent mechanical properties, high obdurability, high rigidity, extremely high energy absorption and wide application prospect.

    本发明公开了一种仿生双相力学超材料及大学生方程式赛车吸能盒,其中,仿生双相力学超材料包括软相单胞微结构和硬相单胞微结构,所述硬相单胞微结构和所述软相单胞微结构采用生物材料中的增韧机制按照两相特定连续排布形式组装成代表性体积单胞。仿生双相力学超材料具有低相对密度,质量轻且具有优异的力学性能,包括较高的强韧性、刚度以及极高能量吸收,应用前途广阔。
