In a sandwich structure which comprises two outer layers (1) fastened to core material (2) which is cut into shaped pieces, preferably to form a checkered pattern, which define gaps (4) therebetween, the gaps (4) are filled with an elastomeric, rubber-like material of a thermosetting resin type. This material is preferably introduced into the gaps in a flowable state, either by injecting the filler under pressure or by suction. |
