Patent ID: 11118292

Abstract:
An impregnation section and a method for impregnating fiber rovings with a polymer resin are disclosed. The impregnation section includes an impregnation zone and a gate passage. The impregnation zone is configured to impregnate the plurality of rovings with the resin. The gate passage is in fluid communication with the impregnation zone for flowing the resin therethrough such that the resin impinges on a surface of each of the plurality of rovings facing the gate passage and substantially uniformly coats the plurality of rovings. The method includes impinging a polymer resin onto a surface of a plurality of fiber rovings, and substantially uniformly coating the plurality of rovings with the resin. The method further includes traversing the plurality of coated rovings through an impregnation zone. Each of the plurality of rovings is under a tension of from about 5 Newtons to about 300 Newtons within the impregnation zone.
