FOAMED PLASTIC BOARD

摘要

The invention relates to a flat structural element (10), as a section from a foam block (5), wherein the foam block (5) is composed of a foamed plastic, comprising a plurality of stacked foam bodies (7) and/or foam bodies (7) composed of body segments (11) that are arranged in a plane next to each other and are connected to each other to form foam bodies (7), said segments having flat weld seams (13) at the abutting surfaces thereof. The foam bodies (7) are welded together into a foam block (5) on the abutting surfaces thereof to form flat weld seams (12). The weld seams (12) between the foam bodies (7) are interrupted by recesses (45) that are disposed at a distance from each other. The flat structural element is preferably used as a core or core layer in sandwich structures, for example in rotor vanes of wind power plants.
