SANDWICH PLATE WITH SANDWICH-CORE USING PYRAMIDAL TRUSS-STRUCTURE, AND ITS MANUFACTURING METHOD

摘要

PURPOSE: A sandwich plate using a pyramidal truss structure and a manufacturing method thereof are provided to have weight lightening, high strength, and high function by applying a pyramidal truss structure to manufacture sandwich plate. CONSTITUTION: A sandwich plate using a pyramidal truss structure comprises pyramidal truss structures(400,500) and two plates(610,620). The pyramidal truss structures have quadrangular pyramid shaped legs radially reaching down. The pyramidal truss structures have isotropic stress and are arranged between the two plates to support both plates at a predetermined interval. The two plates are arranged in parallel.
