Abstract:
1. A method for manufacturing a profiled semifinished fiber-reinforced composite product from a semifinished product of dry fiber or prepreg material, comprising: moving the semifinished product of dry fiber or prepreg material through a forming device in a longitudinal direction thereof, moving the semifinished product between facing forming contours of opposing tool parts in the longitudinal direction of the forming device on a carrier foil, where forming contours of cross sectional shapes of the tool parts continuously change from a cross-sectional contour in an entry region to a forming contour in an outlet region, vibrating a supporting part in an intake region of the forming device with a vibratory unit in such a way that the semifinished product is transformed into a ductile state due to frictional heat generated between the supporting part and the semifinished product, heating the semifinished product in a shaping region downstream from the intake region and upstream of a hardening region with a second heating unit such that the semifinished product reaches a shaping temperature sufficient to take on a contour imposed by the tool parts, heating the semifinished product in the hardening region downstream from the shaping region with a third heating unit such that the semifinished product reaches a hardening temperature sufficient to harden the semifinished product, the hardening region situated in the outlet region, transmitting actuating signals to the vibratory unit to adjust a temperature in the intake region based on a first temperature of the semifinished product measured by a first temperature sensor in the intake region, and controlling a speed of movement of the semifinished product through the forming device based on one or more of the first temperature, a second temperature of the semifinished product measured by a second temperature sensor in the shaping region and a third temperature of the semifinished product measured by a third temperature sensor in the hardening region as the semifinished product moves through the vibrating intake region, the shaping region, and the hardening region.
