Abstract: A lightweight sandwich panel having a core composed of wires and a manufacturing method thereof are provided to improve the rigidity by excluding interference with wires, to enhance the mechanical performance by adjusting the bending angle, arrangement and intervals, and to cut down manufacturing costs by bending wires simply. A sandwich panel is composed of upper and lower face sheets and a truss core. A wire(1) is placed in the upper and lower face sheets, arranged in parallel with an x-z plane, and formed of triangular wave in projecting a plane arranged vertically to a z-axis. The wire is arranged in the sandwich panel and formed of triangular wave having sides arranged alternately in projecting on a plane arranged vertically to a y-axis. The wires are arranged in parallel and placed at regular intervals on the x-z plane. The wires are arranged alternately or twisted repeatedly, and inclined between the parallel wires.

Abstract: Multi-layered three dimensional porous structures and a method of manufacturing the structure are provided to make light, stiff and strong materials due to empty space formed by arranging cells with a pattern. The empty space is possible to be filled with another material or used as a passageway for liquids. In addition, properties on heat transfer, vibration isolation and electric conductivity can be changed by varying porosity of the material. In a three dimensional space, continuous patterns have hexagonal holes regularly in six directions inclined 60° and 120° and inside of the patterns are composed of a group of tetrahedral solids and a group of octahedron cells. A structure having cells similar to Kagome truss is obtained by processing hexagonal holes from 3 or 6 directions inclined 60° and 120° with utilizing HAR(High Aspect Ratio) MEMS(Micro-Electro-Mechanical System) machining process and a machining process capable of making holes with high depth-to-width ratio.
