Manufacturing method of sandwich panels with truss type cores

The present invention up / down as the method of manufacturing a panel comprising a core of the truss structure between the face plates, comprising the steps of parallel arranged at the up / down a certain distance the flange; Sewing performing the up / down after which a mutual parallel movement in the horizontal direction of the face plate by several times the step of reciprocally connected by vertically through the top / bottom face plates of a plurality of flexible wire; And described for the panel manufacturing method comprising the step of securing the maximum spacing that then the flange and the wire both the face plate and then eliminate the relative displacement of the top / bottom surface material in a perpendicular direction while maintaining the parallel state do. In this case, the sewing process is up / down myeonjaeeul the sewing process, but performed in such a way that to pass through the wire in a direction perpendicular to the top / bottom surface material was parallel to the movement previously connection, in a state in which secure the top / bottom flange onto / to pass through the wire in a direction inclined to the face plate and how the stitch also may be performed. When following the method described above, by forming a core material a three-dimensional truss type a new sandwich panels with a core material and a surface ingenuity separate high foregoing paragraph, the weight compared to the compression, shear, bending strength and, also light-weight, yet utilize the empty space inside the it is possible to manufacture at low cost in large quantities.
