摘要： A method for incorporating wet use chopped strand glass (WUCS) in a screw extrusion process is provided. A polymeric resin is added to an extruder in a polymer feed zone and conveyed to a first compression zone where the resin is at least partially melted. The molten resin is conveyed to a high volume zone where WUCS fibers are added. In the high volume zone, the flights of the screw may have a greater pitch to facilitate the introduction of the WUCS into the extruder. The molten resin/fiber mixture is conveyed to a second compression zone where the resin and fibers are intimately compounded. Next, the molten resin/fiber mass is conveyed to a low pressure zone where moisture evaporated from the fibers is released through an opening. The resin/fiber mixture is then conveyed through a compression/die feed zone to further compound and mix the resin and fibers.
摘要翻译：提供了一种在螺杆挤出方法中加入湿用短切玻璃（WUCS）的方法。将聚合物树脂加入到聚合物进料区中的挤出机中并输送到第一压缩区，其中树脂至少部分熔化。将熔融树脂输送到添加有WUCS纤维的高体积区域。在大体积区域中，螺杆的螺纹可以具有更大的间距以便于将WUCS引入挤出机。将熔融树脂/纤维混合物输送到第二压缩区，其中树脂和纤维紧密地混合。接下来，将熔融树脂/纤维物质输送到通过开口释放从纤维蒸发的水分的低压区域。然后将树脂/纤维混合物通过压缩/模头进料区输送以进一步混合并混合树脂和纤维。

摘要： A reinforced chopped strand mat formed of a plurality of chopped reinforcement fibers and at least one continuous element positioned in a substantially parallel orientation in the machine direction is provided. In the reinforced chopped strand mat, the fibers are dispersed in a randomly oriented configuration at least partially surrounding the continuous elements. In preferred embodiments, the continuous element is either a wet continuous glass strand or a dry continuous yarn. The continuous elements are positioned within the chopped strand mat in a parallel or substantially parallel orientation and may be substantially equidistant from each other or irregularly spaced. Desirably, the continuous elements are equidistantly spaced about 0.25 inches to about 3 inches apart. The continuous elements simultaneously improve tensile strength and tear strength of the reinforced chopped strand mat. Methods of forming the reinforced chopped strand mat are also provided.
摘要翻译：提供了由多个切断的增强纤维和至少一个在机器方向上以基本上平行的方向定位的连续元件形成的增强短切纤维网。在增强短切纤维毡中，纤维以至少部分地围绕连续元件的随机取向构型分散。在优选的实施方案中，连续元件是湿式连续玻璃丝束或干式连续纱线。连续元件以平行或基本上平行的方向定位在切碎的股线垫内，并且可以彼此基本等距或不规则地间隔开。理想地，连续元件间隔约0.25英寸至约3英寸。连续元件同时提高加固短切毡的拉伸强度和撕裂强度。还提供了形成增强短切纤维垫的方法。
