Abstract

Extrusion impregnating device for continuous production of unidirectionally fibre-reinforced polymer mouldings with fibre contents between 50 and 70 vol-%, which makes it possible to produce linear profiles with circular, oval or rectangular cross-sections while at the same time enabling high-quality impregnation and the attainment of excellent mechanical characteristics.
