Abstract
The invention relates to novel laminate tubular articles comprising an outer layer having a modulus of at least about 10.sup.7 Pascals, an interior layer comprising a polymeric material having a loss tangent of at least about 0.5 at a temperature of from about 0.degree. C. to about 40.degree. C. at a frequency of from 10-4,000 Hz and whose modulus is less than the modulus of the outer layer and an innermost layer having a modulus greater than the modulus of said interior layer. The invention further relates to a device for sensing in a body of water, said device comprising at least one sensor surrounded by the novel laminate tubular articles of the invention. The mechanical and acoustic properties of the article make it particularly appropriate for use as the hose in a towed-array sonar system.
