摘要：
An automated process is provided for debundling carbon fiber tow that includes feeding a carbon fiber tow into a chopper. The carbon fiber tow is cut to form lengths of chopped tow portions. The lengths of chopped tow portions are distributed on a moving conveyor. The lengths of chopped tow portions are exposed to a first plasma discharge from a first plasma source on the moving conveyor to create debundled carbon fibers. Alternatively, the carbon fiber tow is exposed to the first plasma discharge prior to being cut into lengths. A system for applying chopped fibers to a sheet of molding compound includes a chopper for cutting a carbon fiber tow into lengths of chopped tow portions. A conveyor belt receives the lengths of chopped tow portions. At least one plasma generating source is arrayed across of the conveyor.
