摘要纺织增强复合材料是轻量化结构设计的主要趋势。基于多材料设计的轻量化结构在线健康监测对附加功能集成的需求正在迅速增长。碳丝（CF）似乎是用于纺织增强复合材料应变传感器的最简单、最经济、最耐用的功能元件。本文报道了以CF纱为芯材，聚丙烯纤维为鞘材，用DREF-2000摩擦纺丝生产功能性杂交纱的工艺。对摩擦纺混纺纱和普通纺CF纱（即从制造商收到的形式）的适用性进行了比较研究。对玻璃/聚丙烯热塑性复合材料应用中机电特性的差异进行了分析。此外，还研究了各种类型的碳纤维连接器。
Abstract Textile reinforced composites are a leading trend in lightweight structure design. The demand for additional function integration for the online health monitoring of lightweight structures using multimaterial design is growing rapidly. Carbon filament (CF) seems to be the simplest, most cost effective and most durable functional element for use in textile reinforced composites as a strain sensor. This paper reports on the production of functional hybrid yarn made with DREF-2000 friction spinning using CF yarn as the core component and polypropylene fibres as the sheath component. A comparative study was performed on the suitability of friction spun hybrid yarn and as spun CF yarn (i.e. in the form received from the manufacturer). The differences in electromechanical characteristics were analysed specifically for glass/polypropylene thermoplastic composite applications. Moreover, various types of connectors of CFs were also investigated.
