Abstract
By fitting cores in unidirectionally reinforced composite fibre material articles, it is possible to utilize their high tensile strength in the fibre direction far more because they can be anchored better without special outlay. The cross-section of the cores have to change in the fibre direction and it is important that the fibres run in a clinging fashion on the core and that it is completely embedded therein. The composite fibre material articles provided with cores can be produced continuously. The central region of a glass fibre bundle widens in an impregnation bath, the core inlay is introduced into this region and the fibres are then pressed against the core.
