Abstract
The invention relates to a pultrusion method and arrangements for manufacturing a fibre-reinforced composite product comprising reinforcing fibres embedded in a thermoplastic matrix material. When carrying out the method, the following is performed along a path of pultrusion: providing a preform; further downstream, inductively heating the preform to a processing temperature of the thermoplastic matrix material; and, further downstream, introducing the preform into a die and consolidating the preform by means of the die while the preform passes through the die. Furthermore, arrangements for manufacturing a fibre-reinforced composite product, as well as a fibre-reinforced composite product, are proposed.
