Abstract

In a pultrusion method for manufacturing a fiber-reinforced composite product comprising reinforcing fibers embedded in a thermoplastic matrix material, 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.
