METHOD FOR MANUFACTURING SANDWICH PANEL HAVING CORE OF TRUSS STRUCTURE

摘要

The present invention provides a panel manufacturing method which is a method for manufacturing a panel having a core of a truss structure between upper/lower face sheets, wherein the method comprises the steps of: arranging said upper/lower face sheets in parallel at certain intervals; a sewing step for repeatedly performing, several times, a step of vertically penetrating a plurality of flexible wires into the upper/lower face sheets to perform the reciprocating coupling after said upper/lower face sheets have been mutually and horizontally moved in parallel; and maximally isolating the upper/lower face sheets in a vertical direction while both face sheets are maintained in a parallel state after a relative displacement of said upper/lower face sheets has been resolved, and fixing the face sheets and the wires. In this case, said sewing step, which is performed by vertically penetrating and connecting the wires into the upper/lower face sheets after the upper/lower face sheets have been moved in parallel beforehand, can also be performed by penetrating and sewing the wires in a direction that is inclined toward the upper/lower face sheets while the upper/lower face sheets are fixed. According to the method, by forming the core in a three-dimensional truss type, it is possible to inexpensively manufacture, in large quantities, a new sandwich panel which: has a high separation resistance between the core and the face sheets; shows strong compression, shearing, and bending strengths against the weight; and can make use of the empty inner space with a light weight.
