The invention relates to an injection-structure containing a fibre reinforced semi-finished product (3) in order to produce a fibre reinforced component, which comprises an injection device (1) used to introduce matrix material, a distributing fabric (8) and an impermeable blocking layer (9) for the matrix material. The distributing fabric (8) is disposed between the injection device (1) and the fibre-reinforced semi-finished product (3), and the blocking layer (9) is disposed between the distributing fabric (8) and the fibre-reinforced semi-finished product (3). The invention also relates to a device for producing a fibre-reinforced component by means of said injection structure.

Structure d'injection contenant un produit semi-fini (3) renforcé par des fibres pour la fabrication d'une pièce renforcée par des fibres, qui comporte un dispositif d'injection (1) destinée à l'introduction de matière matrice, une toile de répartition (8) et une couche barrière (9) imperméable à la matière matrice. La toile de répartition (8) est placée entre le dispositif d'injection (1) et le produit semi-fini (3) renforcé par des fibres et la couche barrière (9) est placée entre la toile de répartition (8) et le produit semi-fini (3) renforcé par des fibres. La présente invention concerne également un dispositif de fabrication d'une pièce renforcée par des fibres à l'aide de cette structure d'injection.
