Abstract
An acoustic array hose is provided for towing behind a marine vessel. The acoustic array includes acoustic sensors, a hydraulic fill-fluid circumferentially surrounding the acoustic sensors, and an array hose wall of polyurethane with single wall carbon nanotubes embedded therein. The hose wall circumferentially surrounds the hydraulic fill fluid along a length of the array hose. When an electrical current is applied to the towed array, the nanotubes align with the hose wall with the effect of strengthening the hose wall of the towed array.
