Conditionmonitoring of composite overwrap pressure vessels based on buckypaper sensor and MXene sensor

摘要: Abstract Composite overwrap pressure vessel (COPV) with their excellent specific properties and fatigue resistance are used for high-pressure storage of compressible liquid gaseous fluids in aerospace industries. To predict the life COPV or avoid disasters, MXene buckypaper (BP) sensors embedded to manufacture a smart structure that can help know its strain pressurization state. Hydrostatic tests carried out. The changes measured by BP compared. experimental results show composite have same sensitivity. But sensor is more sensitive initiation propagation microcrack than sensor. For interface between aluminum liner overwrap, plastic deformation compressive residual strains due different microstructure two kinds In word, effective real-time damage Condition monitoring composite. suitable performance structural health condition liner.
