The invention relates to a method for production of fibre composite components (10), particularly suitable for the production of profiles of complicated shape with varying profile cross-section and/or with at least parts with curved lines, such as used for the production of aircraft, for example, with the following steps: (a) production of several core components (12), (b) separate application of a first fibre material (16) to each of the core components (12), (c) assembling the core components (12) provided with the first fibre material (16) to form a sequence of core components (18), (d) application of a second fibre material (20) common to the core component sequence (18) along at least one side of the core component sequence (18), provided with the first fibre material (16), (e) impregnating and hardening the first and second fibre materials (16, 20) to form a fibre-reinforced component body and (f) separation of the component body into several sections as represented by the fibre composite components (10).
L'invention concerne un procédé permettant de produire des éléments composites à base de fibres (10), se prêtant notamment à la fabrication de profilés de structure complexe, à section transversale variable et/ou à tracé en courbe, au moins par endroits, du type de ceux utilisé par ex. comme éléments structuraux dans la construction aéronautique. Ledit procédé comprend les étapes suivantes: (a) préparer plusieurs parties nodales (12), (b) appliquer séparément un premier matériau fibreux (16) sur chaque partie nodale (12), (c) assembler les parties nodales (12) recouvertes du premier matériau fibreux (16), pour former une succession de parties nodales (18), (d) appliquer un second matériau (20) commun à la succession de parties nodales (18), le long d'au moins un côté de la succession de parties nodales (18), sur lequel les parties nodales (12) sont revêtues du premier matériau fibreux (16), (e) infiltrer et durcir le premier et le second matériau fibreux (16, 20), de manière à former un corps d'élément renforcé par fibres et (f) séparer le corps d'élément en plusieurs segments, ces derniers constituant les élément composites à base de fibres (10).
