Measurement of Acoustic Transmission Losses through Grade GS MARBON CYCOLAC and Determination of the Effect of Grazing Angle on Signal Phase.
Abstract
The Applied Research Laboratories, The University of Texas at Austin, was requested by Naval Ship Systems Command, PMS 302-243, to perform acoustic tests on samples of Grade GS MARBON CYCOLAC, an Acrylonitrile-Butadiene-Styrene (ABS) material. The tests investigate the suitability of this material, in thicknesses of 5/16 in. and 3/8 in., for use as a sonar acoustic dome, at frequencies of 80 kHz and 350 kHz. Computer predictions using material characteristics of ABSONIC-A, also an ABS material, indicated satisfactory performance. These tests were used to verify computer predictions. With only minor deviations, expected results were achieved. It was concluded that 3/8 in. thick CYCOLAC exhibited the better performance characteristics at the two frequencies of interest. (Author)
