开孔周期金属桁架结构可以表现出比相同相对密度的随机蜂窝金属结构明显更高的刚度和强度，同时仍然提供高的机械能量吸收和高效的热交换机会。在这里，报告了一种潜在的廉价的基于纺织品的方法来合成周期性金属微桁架层合板。这一过程包括选择钢丝编织，铺设网状物，并使用瞬时液相连接。制作了镍铬(Ni-24Fe-16Cr)丝布的结构实例并进行了测试。它们表现出硬度和强度与相对密度的线性关系，吸收了大量的机械能，并显示出良好的有效热交换潜力。
Open cell periodic metal truss structures can exhibit significantly higher stiffnesses and strengths than stochastic cellular metal structures of the same relative density while still providing high mechanical energy absorption and efficient heat exchange opportunities. Here, a potentially inexpensive textile-based approach to the synthesis of periodic metal microtruss laminates is reported. The process consists of selecting a wire weave, laying up the mesh and joining using a transient liquid phase. Example structures constructed from nichrome (Ni–24Fe–16Cr) wire cloth were made and tested. These exhibited a linear dependence of stiffness and strength upon relative density, absorbed large amounts of mechanical energy, and showed good potential for efficient heat exchange.
