针对重大混凝土结构损伤信息捕捉的完备性,研制碳纤维智能层并提出场域诊断方法。基于碳纤维智能层的功能特性与可覆盖性,将被测结构的力场转换为易于检测的电场,在贴有碳纤维智能层的被测结构中建立一个应变或损伤的敏感场;通过研究碳纤维智能层力、电、热等多场耦合机理,提出服役结构的静态损伤场域诊断方法。最后,展望了水泥基碳纤维智能材料的工程应用及其发展前景。 In view of the completeness of capturing damage information of concrete structures, a smart layer of carbon fiber is developed and a method of field diagnosis is proposed. Based on the functional properties and coverage of the carbon fiber intelligent layer, the force field of the structure under test is converted into an easily detectable electric field, and a sensitive field of strain or damage is established in the measured structure affixed with the carbon fiber intelligent layer. Layer force, electricity, heat and many other coupling mechanisms, proposed service structure static damage field diagnosis method. Finally, the engineering applications of cement-based carbon fiber smart materials and their development prospects are prospected.
