ABSTRACT:
Sandwich panels comprising a top skin and a bottom skin and a connecting core of a plurality of strand connectors are fabricated by applying viscous liquid core material to one of the skins, providing particles with the viscous core material, and reciprocating the particles between the top and bottom skins to form the strand connectors. The strand connectors are permitted to solidify to complete the formation of the sandwich panel. The particles are preferably of a ferrous metal and are driven between the top and bottom skins by a controlled magnetic field. Compound curved and tubular sandwich panels can be formed by the method.
