Abstract:

Acoustic insertion loss of a glass-filament- wound pressure vessel intended for transducer calibration varies significantly as a function of frequency, position, and hydrostatic pressure. The variations are believed to be due to voids in the glass- resin and in the glass-resinrubber liner interface, which give rise to large changes in the characteristic impedance of the composite walls as a function of the same variables. Mechanical behavior of the vessel under hydrostatic pressure required a reduction of specified maximum operating pressure from 2000 PSIG to 1000 PSIG.
