Abstract
The invention provides an intelligent composite material pressure vessel and a manufacturing method related to micro-nano sensors, and relates to the technical field of intelligent composite material pressure vessel manufacturing. The device includes a composite material pressure vessel bottle body and a flexible sensor array; the flexible printed circuit reduces the number of wires and simplifies the arrangement of wires; Any tiny damage to the composite material structure will be transmitted to the microstructure of the micro-nano sensor in real time, manifested as a change in its residual resistance, with very good sensitivity. Compared with traditional resistance strain gauges and fiber grating sensors, it has the advantages of large deformation monitoring, high sensitivity coefficient, wide service temperature, multi-directional monitoring and surface structure health monitoring.
Description
technical field [0001] The invention relates to the technical field of manufacturing intelligent composite material pressure vessels, in particular to an intelligent composite material pressure vessel and a manufacturing method involving micro-nano sensors. Background technique [0002] Pressure vessels are special equipment widely used in production and life that may cause explosion or poisoning. Due to various problems in the design, manufacture, installation and operation of the pressure vessel in service, it leads to abnormal failure, resulting in sudden damage accidents. Composite material pressure vessels have better mechanical properties than all-metal pressure vessels, but their complex structures cause more and more complex damage mechanisms in the process of manufacture and service. In order to avoid extremely harmful accidents such as explosion and poisoning caused by structural damage of composite pressure vessels during the entire working cycle, real-time monit...
