  • Method for monitoring the state of a composite structure and pressurized fluid reservoir having a device performing said method
    Patent number: 6675659
    Abstract: To monitor the operating state of a composite structure formed from at least two different materials and subject to a uniform force or load over its entire surface, the deformation at the interface between the two materials is measured. A comparison with a reference quantity of the structure, normally produced by the force applied thereto, indicates the operating state. When the composite structure forms the wall (14) of a reservoir (10), monitoring takes place in an instrumentation box (30) joined to the reservoir. When a critical threshold is exceeded, an alarm indicator (32) is triggered on the box (30).
