APPARATUS AND METHOD FOR WINDING FIBER REINFORCED¹THERMOPLASTIC RESIN TOW AND PRODUCT THEREOF

摘要

A consolidated structure with less than 5 percent void content and less than .005 inch of axial or hoop ply waviness is formed from a plurality of fiber reinforced thermoplastic resin tows traverse wound on a rotating mandrel by feeding the tows under tension simultaneously from a source of supply to a traversing carriage as adjoining flat tapes. The tapes then move successively through a preheating section, a heated circular guide and a contact point heating source, and a means to apply force to the mandrel which may be a pressurized heating shoe and a chilled roller or only a chilled roller, all on the carriage.
