    • The present invention relates to a method of producing a high strength and high modulus elongated product comprising the steps of (a) making a composition comprising a semi-crystalline polymer and carbon nanotubes, (b) extruding said composition into an elongated product, and (c) stretching the product below the melting point of the polymer, wherein in step (a) the composition is a colloidal dispersion of nanotubes in a solution of the polymer. The advantages of the invention include production of elongated products, like fibres with higher tensile properties, especially strength, with a lower concentration of nanotubes than with a known method.
      The invention also concerns a high strength elongated product containing nanotubes obtainable by the method according to the invention, especially a polyolefin fibre containing nanotubes having a tensile strength of higher than 3.0 GPa. The invention also relates to a process for making composite articles wherein high strength elongated products, preferably fibres, according to the invention are used and to anti-ballistic composites comprising said products.
    • 本发明涉及一种制备高强度和高模量的细长产品,包括以下步骤的方法:(a)制备一种组合物,其包括半结晶聚合物和碳纳米管,(b)挤压所述组合物成细长的产品,和( C)拉伸所述聚合物的熔点以下的产品,则在步骤worin(a)该组合物是纳米管在聚合物的溶液中的胶态分散体。 本发明的优点包括生产细长产品,如具有更高的拉伸性质的纤维,特别是爱的强度,用纳米管比用公知的方法具有较低浓度。 因此本发明涉及一种高强度的细长产品含碳纳米管可获得的由该方法雅丁所述的发明,特别是爱的聚烯烃纤维含有具有高于3.0 GPa的拉伸强度的纳米管。 因此,本发明涉及一种用于制备worin高强度细长产品,优选纤维,gemäß到使用本发明和防弹复合材料包含所述产品的复合材料制品。
