| 先进复合材料的使用为大型工程结构减重、提高效能及降低运营成本提供了有效途径，由于设计、制造与检测技术的限制，复合材料的优越性能在大型结构上的应用还远没得以充分发挥。本文提出了一种与复合材料结构集成一体的可扩展多功能传感网络技术，形成复合材料结构多模式传感能力，使复合材料结构可以“感觉”和“思考”自身状态。为此，发展了在微观尺度上制作高密度电阻温度传感器、电阻应变片和PVDF压电薄膜传感器网络的新方法，利用可扩展的传感器网络搭载层实现了多功能传感器网络从微观到宏观的扩展。扩展后的柔性传感器网络可覆盖面积大、外形复杂的复合材料结构，为全面快速评价复合材料结构在制造及使用过程中的完整性提供有效的技术手段。 |

| The use of advanced composite materials can provide an effective way for reducing weight, improving efficiency and decreasing operating costs of large engineering structures. Because of the limitation of design, manufacturing and detection technology, the superior performance of composite materials is still far from being fully utilized in large engineering structures. In this paper, an expandable multifunctional sensing network integrated with composite structure is proposed to form multimodal sensing capability of composite structures, so that composite structure can “feel” and “think” its own state. For this reason, on the microscopic scale, new methods were developed for fabrication of high density resistance temperature sensor and resistance strain gauge as well as PVDF piezoelectric thin film sensor network, the expansion from microscopic scale to macroscopic scale of multifunction sensor network was realized by using expandable sensor network carrying layer. After expansion, flexible sensor network can cover composite structure with large area and complex appearance, which provides an effective method to evaluate the integrity of composite structure in process of manufacture and use. |
