碳纤维长丝纱传感网络在空间分辨监测用纤维增强复合材料中的应用

Carbon filament yarn-based sensor networks for spatially resolved monitoring of fiber-reinforced composites

纤维增强复合材料应用领域日益增多,其正越来越普遍地成为传统金属结构材料的替代品,特别是在结构成分上,轻质结构相比传统结构具有更显著的生态和经济优势。基于碳纤维长丝纱的传感网络节省了材料,进而减轻了质量,可用于论证力学计算模型、连续监测纤维增强塑料组分的结构及应变。这些方法可被综合运用到增强纺织半成品中,用于空间分辨电阻测量,以便于更深入地了解高技术材料的力学性能。

Fiber-reinforee（t composites are beconling a more and more common substitute for conventional metal construction materials in an ever-growing number of applications, particularly in stnlctural components, where tile realization of lightweight construction eoneepts can create significant ecological and economic advantages over traditional constructions. To save material and thus optimize weight, validate mechanical calculation models, and continuously monitor structures or strains in components made from fiber-reinlbrced plastics in-situ, sensor networks based on carbon tilament yams can be utilized. These can be integrated into the reinfon＇ing textile semifinished product and used for spatially resolved resistive measurements, providing a deept-r insight into the mechanical characteristics of such highteeh materials.
