    Many studies have been conducted for Periodic Cellular Metals(PCMs) to obtain high strength and stiffness for a given weight. To date, a number of structures have been proposed, and they mostly have truss structures such as Pyramid, Octet, Kagome, etc. Recently, Microlattice, a ultra-low density metal(ULDM) composed of hollow trusses was introduced. Microlattice is fabricated based on 3D-lithography technology, which costs very high. In our laboratory, several types of wire-woven structures have been developed as the alternatives of truss PCMs with multiple layers and fine cells. Based on the wire-weaving technology, we introduced a new ultra-low density metal. First, a truss-like structure is assembled using flexible polymer wires. Then, the surface is coated using electroless plating. Finally, the polymer wires are etched out to obtain a hollow tubular structure, micro tube WBK-Q. In this work, we investigate the mechanical properties of the micro tube WBK-Q using FEA
