Abstract
A die and a method for impregnating at least one fiber roving with a polymer resin are disclosed. The die includes an impregnation section comprising an impregnation zone configured to impregnate the roving with the resin. The die further includes a passage at least partially defined in the impregnation section and in fluid communication with the impregnation zone, and a pump in fluid communication with the passage. The method includes coating at least one fiber roving with a polymer resin, traversing the coated roving through an impregnation zone of an impregnation section to impregnate the roving with the resin, and applying an external pressure to the impregnation zone.
