ABSTRACT:
In a method for filling pores between two adjacent layers of a laminate for a component with high demands upon strength and comprising several layers of fibre composite having within each layer substantially parallel fibres embedded in a matrix, a connection path is created, through which a medium may move inside the laminate, between the exterior of the laminate and the pore by exerting the laminate at least in the region of the pore for forces making slots to propagate substantially in the matrix through each laminate layer along the fibre direction of the layer. A flowing, curable material is after that applied at an outer surface of the laminate and this is brought to fill the pore through the connection path. Finally, the material filling the pore is brought to cure.
