Abstract
A fiber placement system is provided that can include a compaction roller defining a plurality of openings between a roller outer surface and a roller inner surface. The plurality of openings are in fluid communication with a vacuum source. A cover can be included in or on the compaction roller so as to block airflow through a portion of the openings. The fiber placement system can also include a head including a frame and at least one supply spool mounted on the frame. The supply spool is supported on a hub for rotation, and the compaction roller is aligned to receive one or more fiber tows from the at least one supply spool. Methods are also provided for laying a prepreg tow material using automated fiber placement.
