国产12K T700级碳纤维在复合芯导线中的替代应用研究

THE REPLACE APPLICATION STUDY OF DOMESTIC 12K T700 GRADE CARBON FIBER IN COMPOSITE CORE CONDUCTOR

在碳纤维复合芯原材料成本构成中,碳纤维占60%以上,采取将复合芯用关键原材料12K T700级碳纤维国产化替代是降低成本行之有效的途径。优选三家国内具有代表性的碳纤维生产企业的12K T700级PAN基碳纤维,制得的三种碳纤维复合芯棒主要性能指标均能满足标准要求,能够替代进口东丽T700S碳纤维,价格约为其70%~80%,有利于碳纤维复合芯导线的推广应用。

The carbon fiber accounted for more than 60% in the raw materials cost of carbon fiber composite core. It is an effective way to cost down by replacing the 12 K T700 grade carbon fiber with domestic fibers. This pater selected three domestic 12 K T700 grade PAN-based carbon fiber to make carbon fiber composite core,for which the main performance can meet the standard requirements. These domestic carbon fibers can replace the imported Toray T700 S carbon fiber with only 70% - 80% of the price,which is beneficial to the popularization and application of carbon fiber composite core conductor.
