| 摘 要： | 从理论上分析了0.5 mm以下小直径单芯液晶聚合物（LCP）光缆在成型过程中，影响光缆抗张强度的主要因素，这些因素主要包括熔融液晶聚合物的温度特性、模芯和模套的结构参数、模芯与模套之间的距离以及光纤的放线张力及其牵引速度等，介绍了各影响因素与光缆抗张强度之间的相互关系，深入分析了光缆加强层厚度与其抗张强度系数之间的相互关系。实验结果证明：小直径液晶聚合物抗张强度与其加强厚度并不存在理想的线性关系，且在一定直径范围内，小直径液晶聚合物光缆具有相同数值的最大抗张强度。

| Abstract: | This paper theoretically analyzed main factors of tensile strength of liquid-crystal po-lymer (LCP) extruded single-core fiber cable with the diameter of 0.5 mm during the forming process. The factors mainly contained temperature feature of the melted LCP, structure parameters of mold core and die sleeve, space between die sleeve and mold core, and tension stringing and traction speed of optical fiber. Results show linear relationship between tensile strength and strengthened story thickness of small-diameter LCP is not ideal. The liquid-crystal polymer extruded fiber cable has maximum tensile strength within a certain diameter. |
