    • 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.
    • 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。

    • A method of co-texturizing glass fibers and thermoplastic fibers comprises passing a glass fiber strand through a texturizing gun, simultaneously passing a thermoplastic fiber strand through the texturizing gun with the glass fiber strand and injecting pressurized air into the texturizing gun concurrently with the glass fiber strand and thermoplastic fiber strands. This method produces a co-texturized fiber material comprising between 20-85% by weight glass fiber and 15-80% by weight thermoplastic fiber having an overall density of from about 20 grams/liter to about 200 grams/liter, and preferably from about 20 grams/liter to less than about 30 grams/liter.
    • 将玻璃纤维和热塑性纤维共混化的方法包括将玻璃纤维束穿过组织化枪,同时使热塑性纤维束通过玻璃纤维束通过组织化枪,并将加压空气与玻璃纤维同时注入到组织化枪中 股和热塑性纤维股。 该方法产生共组织纤维材料,其包含20-85重量%的玻璃纤维和15-80重量%的总密度为约20克/升至约200克/升的热塑性纤维,优选约为约 20克/升至小于约30克/升。
