Abstract
An impregnation section of a die and a method for impregnating at least one fiber roving with a polymer resin are disclosed. 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 defining a cut-away portion downstream in a run direction of the roving of a point-of-contact for the at least one of the plurality of contact surfaces. The at least one of the plurality of contact surfaces further includes an edge defined by the cut-away portion. Excess material build up is reduced by the cut-away portion.
