Carbon nanotube composite material structural health monitoring system

Abstract

The invention discloses a carbon nanotube composite material structural health monitoring system which comprises a mechanical testing device, a carbon nanotube sensor, a data acquisition module, a data transmission module, a data receiving module, a computer, a cloud storage module and a mobile terminal module; through the application of carbon nanotubes as sensors to structural health monitoringof materials, real-time monitoring of cracks on the surface and inside a product can be realized, and engineering technicians can be guided to respond in time; most of the existing products are basically started to be detected after structural parts are found to be damaged, thereby frequently leading to major engineering accidents, and seriously damaging people's life and property security; by utilizing the carbon nanotubes as the sensors for real-time and comprehensive structural health monitoring, the work efficiency can be effectively improved, and the people's life and property security can be protected.

Description

technical field [0001] The invention relates to the technical field of composite material structure health monitoring systems, in particular to a carbon nanotube composite material structure health monitoring system. Background technique [0002] At present, it is very difficult to monitor internal cracks in steel structures. There is no technology that can sensitively detect tiny cracks in steel structures, which poses a great hidden danger to the use of steel. The technology of periodic and continuous detection of damage mainly includes metal wire strain sensors, optical fiber sensors, and piezoelectric sensors. However, because a large amount of wiring is required in the monitoring process, data analysis is complicated, and it affects the use, it has not been applied in large-scale engineering. [0003] As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many unusual mechanical, electrical, and ch...
