带有上游表面的浸渍部件以及用于浸渍粗纱纤维的方法
摘要：
本发明涉及一种模具浸渍部件和一种采用聚合物树脂用于浸渍至少一根纤维粗纱的方法。浸渍部件包括构造成用以采用树脂浸渍粗纱的浸渍区域，以及与浸渍区域流体连通、用于使树脂在其中流动通过以便用树脂涂覆粗纱的闸门通道。另外，浸渍部件还包括沿着粗纱的行进方向布置在浸渍区域的上游、用于接触粗纱的表面。所述方法包括：使至少一根纤维粗纱横越表面；使聚合物树脂流动通过间隙，该间隙在接近0.1毫米到接近4毫米之间的范围内；采用树脂涂覆粗纱；以及使被涂覆的粗纱贯穿通过浸渍区域，以采用树脂浸渍粗纱。
摘要（英）：

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 and a gate passage 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 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, 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 to impregnate the roving with the resin.
