Abstract
A die and method for impregnating at least one fiber roving with a polymer resin are disclosed. In one embodiment, the die includes an impregnation section including an impregnation zone configured to impregnate the roving with the resin, the impregnation zone including a plurality of contact surfaces. The die further includes a perturbation positioned on at least one of the plurality of contact surfaces, the perturbation configured to interact with the roving. In one embodiment, the method includes coating a fiber roving with a polymer resin. The method further includes traversing the coated roving through an impregnation zone to impregnate the roving with the resin. The impregnation zone includes a plurality of contact surfaces. The method further includes interacting the coated roving with a perturbation positioned on at least one of the plurality of contact surfaces.
