Abstract

Abstract: Composite overwrap pressure vessel (COPV) with their excellent specific properties and fatigue resistance are used for high-pressure storage of compressible liquid and gaseous fluids in aerospace industries. To predict the life of COPV or avoid disasters, MXene and buckypaper (BP) sensors are embedded in COPV to manufacture a smart structure that can help COPV to know its strain and pressurization state. Hydrostatic pressure tests are carried out. The changes in resistance measured by MXene and BP sensors are compared. The experimental results show MXene and BP sensors embedded in composite overwrap have the same sensitivity. But BP sensor is more sensitive to the initiation and propagation of microcrack in COPV than MXene sensor. For MXene and BP sensors embedded in the interface between the aluminum liner and composite overwrap, MXene is more sensitive to plastic deformation or compressive residual strains than BP sensor due to the different microstructure of the two kinds of the sensor. In a word, BP sensors are effective for real-time damage Condition monitoring of composite. MXene sensors are more suitable for the performance and structural health condition monitoring of aluminum liner. Graphical abstract: The different microstructure of The MXene and BP sensors determine different piezoresistive responses. And two kinds of sensors integrated into the COPV provide a more efficient method to monitor the structural integrity and understand the mechanical properties of COPV. Image 1 Highlights: In this work, we may be one of the first people who embedded MXene sensors and buckypaper sensors in composite overwrapped pressure vessel to detect strain and pressurization state, and the presence of plastic deformation or damage of structure during Hydrostatic pressure tests. BP sensor is more sensitive to the initiation and propagation of microcrack in COPV than MXene sensor. MXene is more sensitive to plastic deformation or compressive residual strains than BP sensor due to the different microstructure of two kinds of sensor.
