In a method for producing a hull wall of a fiber composite sandwich component, shaped bodies of extruded polystyrene hard foam are enveloped with an envelope of fiber composite material with fibers oriented at least bidirectionally. The enveloped shaped bodies have a shape for forming a hull wall and are placed next to each other in a vacuum injection structure on a lower cover layer of fiber composite material. An upper cover layer of fiber composite material is placed on top of the enveloped shaped bodies and the vacuum injection structure is sealed. Matrix material is introduced and distributed in the vacuum injection structure until the fiber composite material of the envelopes and of the upper and lower cover layers is impregnated completely with the matrix material. The matrix material is cured and the fiber composite sandwich component of the hull wall is removed from the vacuum injection structure.
