    摘要： A flat and nearly mechanically isotropic polymer film or sheet, or a tube, can be formed by laminating two or more films, preferably by coextrusion of a liquid crystal polymer film and a thermoplastic polymer film. A liquid crystal polymer layer may be combined with one or more thermoplastic polymer layer in various arrangements. The liquid crystal, and possibly the thermoplastic as well, may have a controlled molecular orientation. The film may be formed by passing a polymer through a set of two or three tubular rotors which are concentric and have facing surfaces which define inner and outer annular polymer flow channels.

    摘要： Coatings of multiaxially oriented Thermotropic Liquid Crystalline Polymer (TLCP) are provided to elongated members. Suitable members include glass rods, glass fibers, pipes, beams, and other oval or polygonal members having an essentially regular cross-section. Members of ceramic, plastic, or metal can also be coated. This extrusion is performed using a die having inner and outer mandrels capable of rotating in opposite directions. Concentricity between inner and outer mandrels of the die is maintained to assure uniform coating thickness. In order to produce a high level of multiaxial orientation at lower die rotational speeds, the die design may include spiraling feed zones on one or both facing surfaces of the inner and outer mandrels. The application of the multiaxially oriented coating provides superior impermeability to water vapor and oxygen, and increased strength to the elongated member in the axial direction.

    摘要： The present invention is based upon the discovery that ordered polymers, such as PBzT, can be readily formed into tubular structures which retain a biaxial orientation imparted thereto during processing, and that these rigid, high-stiffness tubular components can exhibit near zero coefficient of thermal expansion (CTE). Zero CTE materials are not adversely affected by vast swings in temperature, e.g., from very hot to very cold in short periods of time, nor are they adversely affected by long term exposure to either temperature extreme. The tubular components of the present invention thus represent a revolutionary advance in space based hardware, as the extreme temperatures experienced there will not affect rigidity of structures built using these components.

    摘要翻译： 本发明基于如下发现：有序聚合物例如PBzT可以容易地形成为在加工过程中保持双轴取向的管状结构，并且这些刚性的，高刚度的管状部件可呈现接近零的热系数 扩展（CTE）。 零CTE材料不会受到温度波动的不利影响，例如在短时间内从非常热到非常寒冷，也不会长期暴露于任何一种温度极端而受到不利影响。 因此，本发明的管状部件代表了基于空间的硬件的革命性进步，因为经历的极端温度将不会影响使用这些部件构造的结构的刚性。
