Abstract : A radially compliant acoustic line array hose with improved toughness and wear resistance, suitable for use in towed acoustical line array sonars. The hose comprises a long extruded cylindrical tubing of a soft flexible grade of geophysical, plasticized polyvinyl chloride material with longitudinal ribs of a stiffer, harder grade of geophysical plasticized polyvinyl chloride material located at or near the tubing surface, and spaced uniformly around the circumference of the tubing. The ribs are melt-bonded to the softer thermoplastic material while each is in their respective melt stages during the extrusion process.
