摘要:
A process for the production of a fibre-composite material, the process including the following steps: a) a fibre bundle is conducted over at least one deflection bar having radially circumferential rounded elevations, thus being expanded; b) the expanded fibre bundle is subsequently drawn into an impregnation chamber; c) a melt is applied to the expanded fibre bundle; and d) the fibre bundle impregnated with melt is drawn through a take-off die at the end of the apparatus, and a corresponding device, which achieves very good impregnation quality.
