Laminated structural panels and the method of producing them involve selection of a desired member of sheets of sheet metal of the desired thickness and material, perforating one or more of the sheets to a desired pattern depending upon characteristics desired such as lightness, stiffness or inclusion of fluid passageways etc., stacking the perforated sheets with imperforate face sheets top and bottom and, with brazing material at the interface between the sheets, subjecting the stack to a temperature high enough to cause melting of the brazing material while maintaining a very high vacuum environment. In an alternative embodiment, one or more imperforate internal sheets may be interleaved between the perforated sheets.
