註釋Aluminum alloy-lined fibre glass reinforced (FRP) plastic hoop-wrapped cylinders are designed so that at the burst pressure of 51.7 MPa the load is equally shared by the metallic liner and the FRP. Autofrettage or tape wrapping under tension allows the metallic liner to remain under compressive stress and the FRP in tension while the vessel remains unpressurized, thus enhancing the fatigue life of the metallic liner. This report gives the results of an investigation of cylinder degradation in the laboratory. Residual life and pressure retaining capacity of cylinders were established as a function of degrees of damage to the FRP using acoustic emissions.
