| Summary | Results from a series of cyclic tests performed on fiberglass pipes fabricated according to RTP-1 and Section X recommendations. The specimens were 20.32 cm (8 in) in internal diameter and 1.525 meters (5 feet) long. The construction layout consisted of an internal buildup for corrosion protection followed by a layer of continuous fiber winding. A state of pure hoop stress was imposed via an internal pressure system that allowed free axial movement of the pipe. This paper will present the results of the acoustic emission monitoring of these tests, and the relative effectiveness of AE in determining damage induced by cyclic loading. |
