Fibre composite laying device and fibre composite laying method for producing a fibre composite scrim for forming a fibre composite component

摘要

A fibre composite laying device 1, and method thereof, for producing a fibre composite scrim for forming a fibre composite component comprises a laying head 3 to continuously supply a reinforcement fibre band 2; a compaction roller 4 to receive, lay and press the fibre band onto the laying surface at an average compaction pressure; and a plurality of pressure sensors 6 on the compaction roller to detect a local compaction pressure. Preferably, the roller adjusts the average compaction pressure on the basis of the detected local compaction pressure using a plurality of actuators 7 arranged on the roller; whereby at least some of the pressure sensors may be actuators. Preferably, the pressure sensors may comprise a sensor array 8 and may substantially cover the entire compaction surface. The pressure sensors may comprise a pressure sensitive flexible diaphragm or piezoelectric elements and may be embedded in a protective layer. A radiation source 10 and radiation sensor 11 designed to detect reflected radiation may be provide with an evaluation unit 12 in order to establish laying errors; wherein the compaction roller, and at least some of the pressure sensors, may be transparent to radiation at least in regions.
