Abstract

Abstract: Pressure vessels are always under different hazards such as leaking, fracturing, and unknown deformation. In this work, the novel micro-nano sensors were introduced based on flexible printed circuit (FPC). The temperature cycling and hydraulic pressure cycling experiments were carried out. This kind of combined sensor can be embedded and arranged between inner tank and fiber layer without any defect. The experimental results show the new sensor can detect not only thermal strain, but also elastic deformation and plastic deformation caused by pressure. Also can reflect the yield limit of COPV, which can ensure the safety of manufacture. Graphical abstract: Flexible circuit sensor array and sensing mechanism of the micro-nano sensors. Image 1 Highlights: Micro-nano sensors can be integrated into composite pressure vessel without defects. Micro-nano sensors combined with flexible circuits can form monitoring array. Monitor micro deformation and thermal residual stress caused by temperature change. Monitor lateral and longitudinal deformation simultaneously caused by water pressure.
