Abstract
本发明是由纤维-聚合物复合材料支承的导体，其具有纤维-聚合物复合芯和管状金属导体。所述管状金属导体在所述芯之上。由布置所述导体导致的基本上所有机械张力由所述纤维-聚合物复合芯来承担。
Description
本发明涉及支承的高架电缆。特别地，本发明涉及由纤维-聚合物复合材料支承的高架电缆。
目前，使裸露的铝导体高架电线，如铝导体钢增强的(aluminum conductorsteel reinforced)(ACSR)和铝导体钢支承的(aluminum conductor steelsupported)(ACSS)，构造有钢芯以此支撑它们的重量。纤维增强高分子复合材料可以用来替代钢芯。
纤维增强高分子复合材料可以提供重量和强度方面的优势。另一方面，高分子复合材料也具有下述方面的缺点：耐疲劳性、抗扭强度、和表面耐磨损性。由于高架线材应该具有超过60年的使用寿命，因此解决疲劳、抗扭强度、和表面磨损的问题对于钢芯电线的可替代物的有效性是关键性的。
需要提供铝导体纤维-聚合物复合材料支承的高架电线，其克服了与耐疲劳、抗扭、耐表面磨损性相关的缺点。此外，纤维增强高分子复合芯应该表现足以满足ASTM B 341/B 341M-02的机械性能并且具有高伸长率和高模量。该复合芯也应该表现耐高温性和高断裂韧度。也需要通过在挤拉成型之前使松散的连续纤维预成型为特定的微观结构来降低挤拉成型法的复杂性。此外，期望的是，用更轻更强的合成材料(即，较高的强度重量比率)替代钢芯。
尽管铝导体纤维-聚合物复合材料支承体应该足以解决高架需要，但是本领域普通技术人员将容易认识到该支承体对其它应用(包括海底光纤电缆)的有效性。
图1展示了本发明的纤维-聚合物复合材料的微观结构，其中该微观结构由以下两者组成：沿芯的纵向方向排列的轴向纤维、以及以某螺旋角度在轴向纤维周围编结的加捻纤维(twisted fibers，合股纤维)。
图2展示了由纤维-聚合物复合材料支承的铝导体。
本发明是由纤维-聚合物复合材料支承的高架导体，其包括(a)纤维-聚合物复合芯和(b)管状金属导体。所述管状金属导体在所述芯之上，并且具有这样的组成和柔软韧度(soft temper)使得，对于所有的导体操作温度而言，当环境温度高于冰和雪会在该导体上堆积的温度时，由紧张地高架(strung-overhead)布置所述导体导致的基本上所有机械张力由纤维-聚合物复合芯承担，而如果需要管状金属导体来承担任何随之而来的应力时，所述管状金属导体就宁可无弹性地伸长而将这种应力留给纤维-聚合物复合芯来承担。
优选地，所述纤维-聚合物复合芯是碳纤维-增强高分子组合物，其包括碳纤维和环氧树脂。更优选地，所述碳纤维的存在量应该为约70wt％至约90wt％，更优选地，约75wt％至约85wt％，并且甚至更优选地，约78wt％至约85wt％。
优选地，所述碳纤维的弹性模量将大于或等于约80GPa。更优选地，所述弹性模量将大于或等于约120GPa。此外，优选地，所述碳纤维的失效极限伸长率将大于约1.5％。
所述环氧树脂可以是单一树脂或多于一种树脂的混合物。优选地，所述环氧树脂的存在量应该为约10wt％至约30wt％，更优选地，约15wt％至约25wt％，并且甚至更优选地，约15wt％至约23wt％。优选地，所述环氧树脂是热固性环氧树脂。更优选地，所述树脂的玻璃化转变温度将高于约150摄氏度。
所述碳纤维-增强高分子组合物可以进一步包括短切碳纤维、碳纳米管、或两者都包括。当存在时，优选地碳纤维或碳纳米管的存在量为约0.5wt％至约10wt％，更优选地，约1wt％至7wt％，并且甚至更优选地，约1wt％至约5wt％。
所述碳纤维-增强高分子组合物可以进一步包括硬化剂。硬化剂的存在量将取决于用来制备组合物的环氧树脂的用量和类型。
所述管状金属导体可以由传导金属组成。优选地，所述金属导体将为铝。更优选地，管状铝导体的电导率不低于61％IACS。
本发明的交替实施方式使得，在挤拉成型过程之前使连续纤维预成型为特定的微观结构。这些微观结构由以下两者组成：沿芯的纵向方向排列的轴向纤维、以及以某螺旋角度在轴向纤维周围编结的加捻纤维。据信，较高的螺旋角度将通常增加抗扭强度。
优选地并且在挤拉成型法的过程中，将短切碳纤维或碳纳米管加入到环氧树脂中。
优选地，轴向纤维与在轴向纤维周围编结的加捻纤维的比率为约50％至约95％。认为应该达到拉伸强度与扭转/弯曲刚性之间的平衡。这样的话，认为在选择该比率时应该多加注意，因为该比率的增加将增加拉伸强度但会产生复合芯的扭转/弯曲强度的降低。
优选地，编结的纤维的螺旋角度应该为约15度至约55度。至于轴向纤维与加捻纤维的比率，则认为应该达到拉伸强度与扭转/弯曲硬度之间的平衡。这样的话，认为在选择该螺旋角度时应该多加注意，因为该角度的增加将降低拉伸强度但会增加复合芯的扭转/弯曲强度。
再在另一种实施方式中，本发明是由纤维-聚合物复合材料支承的导体，其包括(a)纤维-聚合物复合芯；(b)覆盖在所述芯之上的管状导体，其具有这样的组成和柔软韧度使得，对于所有的导体操作温度而言，由紧张地布置所述导体导致的基本上所有机械张力由纤维-聚合物复合芯承担，而如果需要管状导体来承担任何随之而来的应力时，所述管状金属导体就宁可无弹性地伸长而将这种应力留给纤维-聚合物复合芯来承担。所述管状导体传输电力或信息。
再在另一种实施方式中，本发明是纤维-聚合物复合芯。该复合材料包括一根或多根编结的“宏观-线材(macro-wires)”。所述“宏观-线材”在预成型过程之后可以具有或可以不具有正方形横截面。优选地，当将所述“宏观-线材”挤拉通过圆形模头时，其将符合地形成圆形横截面。
