    • An improved method of manufacturing articles containing carbon fibers when the fibers are temporarily plasticized to render them more flexible thereby permitting tortuous mechanical manipulation of the fibers to be carried out with little or no mechanical damage. The improvement comprises exposing the carbon fibers to agents capable of intercalating single crystals of graphite, such as bromine or iodine monochloride which have the effect of plasticizing the fibers by lowering their tensile modulus. While the fiber yarns are appreciably more flexible in the plasticized state, and have a higher elongation-at-break, on removal of the plasticizer they tend to return to their original state but retain a measurable degree of the shape imparted to them.
    • 一种改进的制造含有碳纤维的制品的方法,其中纤维被暂时塑化以使它们更具柔性,从而允许纤维的曲折机械操作以很少或没有机械损伤进行。 该改进包括将碳纤维暴露于能够嵌入石墨单晶的试剂,例如溴或碘一氯化物,其具有通过降低其拉伸模量来增塑纤维的作用。 虽然纤维纱在增塑状态下明显更具柔性,并且具有较高的断裂伸长率,但在去除增塑剂时,它们趋向于恢复到其原始状态,但是保留了赋予它们的形状的可测量的程度。

    • A multilayer polymeric film having dead bend characteristics which are substantially planar isotropic is a laminate of at least two layers of one or more polymeric films, in which:A. each polymeric film layer is highly oriented in one direction, such that each polymeric film layer has dead bend properties with respect to bending deformations substantially normal to the direction of orientation; andB. the direction of orientation of each polymeric film layer forms an angle of at least about 30 degrees with the direction of orientation of each adjacent polymeric film layer.A method for making the multilayer polymeric film having dead bend characteristics also is provided.

    • Provided is a process for melt spinning a partially oriented yarn of increased birefringence, and hence higher orientation, for a given wind-up speed. The process comprises extruding a molten fiber forming polyester through a shaped orifice to form a molten filamentary material, which is then passed in the direction of its length into a quench zone wherein the filamentary material is contacted with a first gaseous quenching medium. While the filamentary material is still in a deformable state, however, it is passed through a hot zone provided with an atmosphere having a temperature greater than the first gaseous quenching medium and greater than the glass transition temperature of the molten polyester filamentary material. The filamentary material is then withdrawn from the hot zone and contacted with a second gaseous quenching medium at a temperature below the glass transition temperature of the filamentary material until the filamentary material is no longer deformable, after which the filamentary material is withdrawn from the quench zone.
    • 提供了一种用于在给定的卷绕速度下熔融纺丝部分取向纱线的方法,所述纱线具有增加的双折射,并且因此更高的取向。 该方法包括通过成形孔挤出形成聚酯的熔融纤维以形成熔融丝状材料,然后将其熔融丝状材料沿其长度方向通入骤冷区,其中丝状材料与第一气态淬火介质接触。 然而,当丝状材料仍然处于可变形状态时,其通过具有大于第一气态淬火介质的温度大于熔融聚酯长丝材料的玻璃化转变温度的气氛的热区域。 然后将丝状材料从热区域中取出,并在低于丝状材料的玻璃化转变温度的温度下与第二气态淬火介质接触,直到丝状材料不再变形,然后将丝状材料从骤冷区域中取出 。
