A LIGHT WEIGHT SANDWICH PANEL WITH A CORE CONSTRUCTED OF WIRES AND THE MANUFACTURING METHOD OF THE SAME

摘要

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.
