Abstract
A die and method for impregnating at least one fiber roving with a polymer resin are disclosed. The die includes an impregnation section. The impregnation section includes an impregnation zone configured to impregnate the roving with the resin. The impregnation zone includes a plurality of contact surfaces. At least one of the plurality of contact surfaces is configured such that a normal force of the roving is less than or equal to a lift force of the resin at an impregnation location on the contact surface during impregnation of the roving with the resin by the contact surface.
