The present invention relates to a method of manufacturing a fibre-reinforced laminate (101), which laminate comprises at least one area on the surface of the laminate configured with projecting fibres for being joined to one or more other elements. This is accomplished by arrangement of a hybrid mat (505) most distally in the laminate which comprises at least two layers with fibres (105) transversally across the joining face (402) of the layers. The outermost layer (301) of the hybrid mat is removed prior to joining, whereas the innermost layer (506) of the hybrid mat remains a constituent of the laminate (101). The invention relates to different methods of causing fibres to project from the surface of the laminate, said fibres thus having a reinforcing effect on the joints. The invention also relates to a laminate manufactured by the disclosed methods and a blade for a wind power plant comprising such laminate.
L'invention concerne un procédé permettant de produire un stratifié (101) fibreux, la surface de ce stratifié comprenant au moins une zone présentant des fibres protubérantes destinées à être assemblées à un ou à plusieurs autres éléments. Pour produire ce stratifié, on dispose un mat (505) hybride sur la partie externe du stratifié, ce mat comprenant au moins deux couches, et des fibres (55) disposées transversalement aux surfaces (402) des couches. La couche externe (301) du mat hybride est détachée avant l'assemblage, tandis que la couche (506) interne du mat forme une partie intégrante du stratifié (101). L'invention concerne différents procédés permettant d'obtenir des fibres qui dépassent à la surface du stratifié, et qui permettent ainsi de renforcer les joints. L'invention concerne en outre un stratifié produit au moyen des procédés décrits, ainsi qu'une pale pour éolienne, comprenant un tel stratifié.
