Zusammenfassung:	An automated fiber placement (AFP) system includes a tool head with a compaction roller and a first variable heat source. The compaction roller is configured to receive at least one of a fiber and a plurality of fibers formed as a laydown tape, and is controlled to apply the laydown tape to a workpiece at a predetermined speed and direction. The first variable heat source is configured to apply a first amount of heat to the laydown tape. The first amount of heat applied is related to the predetermined speed. The AFP system further includes a second variable heat source configured to apply a second amount of heat to the workpiece. The second amount of heat applied is related to at least one of: a position on the workpiece, a thickness of the workpiece at that position, and a separation distance between the second variable heat source and the workpiece.
