Claim Text:
1. A die for impregnating at least one fiber roving with a polymer resin, the die comprising: an impregnation section comprising an impregnation zone configured to impregnate the at least one fiber roving with the resin, the impregnation zone comprising a plurality of stationary contact surfaces; a plurality of perturbations positioned on at least one of the plurality of contact surfaces, each of the plurality of perturbations configured to disturb a run direction of the at least one fiber roving; a manifold assembly comprising a channel for flowing the resin therethrough; and a gate passage positioned between the manifold assembly and the impregnation section, the gate passage configured to flow the resin from the manifold assembly to the impregnation section, wherein the impregnation section is configured such that the at least one fiber roving is traversed therethrough in the run direction generally transverse to a flow direction of the resin as the resin exits the gate passage; and wherein each of the plurality of perturbations is spaced apart from others of the plurality of perturbations along a direction perpendicular to both the run direction of the at least one fiber roving and the flow direction of the resin as the resin exits the gate passage.
