    • A micro-truss based blast protection apparatus. In one embodiment, the blast protection apparatus includes a three-dimensional (3D) ordered truss core between a first face plate and a second face plate. The 3D ordered truss core includes first truss elements defined by first self-propagating polymer waveguides and extending along a first direction, second truss elements defined by second self-propagating polymer waveguides and extending along a second direction, and third truss elements defined by third self-propagating polymer waveguides and extending along a third direction. The first, second, and third truss elements interpenetrate each other at a plurality of nodes to form a continuous material. The first, second, and third truss elements define an open space for providing a densification in response to a force applied to the first face plate and/or the second face plate, and the 3D ordered truss core is self-supporting.
    • 一种微型桁架式防爆装置。 在一个实施例中,防爆装置包括在第一面板和第二面板之间的三维(3D)有序桁架芯。 3D有序桁架芯包括由第一自传播聚合物波导限定并沿着第一方向延伸的第一桁架元件,由第二自传播聚合物波导限定并沿着第二方向延伸的第二桁架元件,以及由第三自身限定的第三桁架元件 - 传播聚合物波导并沿着第三方向延伸。 第一,第二和第三桁架元件在多个节点处相互渗透以形成连续材料。 第一,第二和第三桁架元件限定用于响应于施加到第一面板和/或第二面板的力提供致密化的开放空间,并且3D有序桁架芯是自支撑的。

    • A method for creating or forming a functionally graded 3D ordered open-cellular microstructure, and a functionally graded 3D ordered open-cellular microstructure. In one embodiment, the functionally-graded three-dimensional ordered open-cellular microstructure includes a first three-dimensional interconnected pattern of polymer waveguides having a first three-dimensional pattern; a second three-dimensional interconnected pattern of polymer waveguides having a second three-dimensional pattern differing from the first three-dimensional pattern; and an interface connected with the first three-dimensional interconnected pattern of polymer waveguides and the second three-dimensional interconnected pattern of polymer waveguides. Here, the term “functionally graded” refers to a spatial variation in the physical microstructure—and thus the properties—through the thickness of the material.
    • 一种用于创建或形成功能梯度的3D有序开放细胞微结构的方法,以及功能梯度的3D有序开放细胞微结构。 在一个实施例中,功能梯度的三维有序开孔细胞结构包括具有第一三维图案的聚合物波导的第一三维互连图案; 具有不同于第一三维图案的第二三维图案的聚合物波导的第二三维互连图案; 以及与聚合物波导的第一三维互连图案和聚合物波导的第二三维互连图案连接的界面。 这里,术语“功能梯度”是指物理微观结构的空间变化,因此是材料的厚度的特性。
