Componente estructural de varias capas (84, 110, 120, 170) - que comprende una primera y una segunda capa de material compuesto de fibras (102, 104, 122, 124, 172, 174) y una capa de espuma (106, 126, 176) de plástico espumado dispuesta entremedias, - presentando la primera y la segunda capa de material compuesto de fibras (102, 104, 122, 124, 172, 174) en cada caso al menos un estrato de fibras (4, 16, 18, 24) de un material de fibras, caracterizado porque el material de fibras está incrustado en una matriz (8, 20) a base de un plástico termoplástico, y el componente estructural (84, 110, 120, 170) comprende una estructura de anclaje (140) - con una base (142) para la unión a un elemento de introducción de fuerza y - con una estructura de ramificación (146), comprendiendo la estructura de ramificación (146) al menos tres ramales (148a-f) que se extienden desde la base (142) en distintas direcciones, estando incrustada la estructura de ramificación (154) de la estructura de anclaje (140) en la capa de espuma (106, 126, 176).
The invention relates to a multilayer structural component (84, 110, 120, 170) comprising a first and a second fibre-composite layer (102, 104, 122, 124, 172, 174) and a foam layer (106, 126, 176), arranged in between, made of foamed plastics material, wherein the first and the second fibre-composite layer (102, 104, 122, 124, 172, 174) each have at least one fibrous layer (4, 16, 18, 24) made of a fibre material, said fibrous layer being embedded in a thermoplastic-based matrix (8, 20). The structural component has an anchoring structure (140) for attaching to a force introduction element. The invention furthermore relates to a method for producing a structural component (84, 110, 120, 170), in which a first and a second fibre-composite sheet (2, 12, 48, 52) are provided, wherein the first and the second fibre-composite sheet (2, 12, 48, 52) each have at least one fibrous layer (4, 16, 18, 24) made of a fibre material, said fibrous layer being embedded in a thermoplastic-based matrix (8, 20), in which the first fibre-composite sheet (2, 12, 48, 52) is thermoformed to form a first fibre-composite semifinished product (64, 86, 88) and the second fibre-composite sheet (2, 12, 48, 52) is thermoformed to form a second fibre-composite semifinished product (64, 86, 88), in which the first and the second fibre-composite semifinished product (64, 86, 88) are arranged in a foaming mould (90) such that a cavity (96); is formed between the first and the second fibre-composite semifinished product (64, 86, 88), and in which the cavity (96) is foamed by injection of a foaming plastics material. Furthermore, the anchoring structure (140) is integrated into the structural component.
