摘要: As a result of the high specific strength/stiffness to mass ratio, filament wound composite pressure vessels are extensively used contain gas or fluid under pressure. The ability in-situ monitor for possible damage is important high-pressure medium storage industries. This paper describes an monitoring method permanently their structural integrity. sensor made multi-walled carbon nanotube (MWCNT) that can be embedded in skin vessels. sensing firstly evaluated various mechanical tests, and experiments full-scale vessel during hydraulic fatigue cycling pressurization performed. results MWCNT compared with strains measured by strain gauges. show signal developed matches behavior laminates load conditions. In test, relationship between resistance built, could quantitative vessel. bursting detected sharp increase resistance. Embedding into successfully demonstrated as promising health monitoring.
