An impregnation section of a die (150) and a method for impregnating at least one fiber roving with a polymer resin are disclosed. The impregnation section includes an impregnation zone (250) configured to impregnate the roving (142) with the resin and a gate passage (270) in fluid communication with the impregnation zone for flowing the resin therethrough such that the resin coats the roving. Additionally, the impregnation section includes a surface (253) disposed upstream of the impregnation zone in a run direction of the roving for contacting the roving. The method includes traversing at least one fiber roving over a surface, flowing a polymer resin through a gap (274), the gap being in the range between approximately 0.1 millimeters and approximately 4 millimeters, coating the roving with the resin, and traversing the coated roving through an impregnation zone (250) to impregnate the roving with the resin. |
