Title:
3-DIMENSIONAL LATTICE TRUSS STRUCTURE COMPOSED OF HELICAL WIRES AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/025268
Kind Code:
A2
Abstract:
The present invention relates to a 3-dimensional lattice truss structure composed of helical wires and a method for manufacturing the same. The present invention provides the 3-dimensional lattice truss structure, which is assembled by intercrossing 3-directional or 6-directional consecutive helical wire groups having a predetermined azimuth angle (e.g., 60 degrees or 90 degrees) to each other in space such that the structure formed in a specific shape has a high strength and stiffness-to-weight ratio and creates three new truss forms with a large surface area; and a low-cost/mass production (manufacturing) method thereof. According to the present invention, instead of weaving and stacking net-shaped wires, helical wires are directly assembled three dimensionally in a continuous process and each has a structure that is very similar to an ideal hexahedron truss, octet truss or combined truss of octahedron and 14-hedron. In this manner, 3-dimentional lattice truss structures having outstanding mechanical properties or thermal and aerodynamic characteristics can be manufactured.
