Abstract
A jacket for a liquid filled towed array is formed from a composite material formed from short lengths (typically 2-4 mm) of reinforcing fibre (1) which are mixed with a thermoplastic material (2) to form the jacket (3). The reinforcing fibre (1) is preferably either glass fibre, aramid fibre, or carbon fibre or a mixture thereof and provides the desired high Tensile Modulus. The thermoplastic material (2) provides a relatively high level of viscoelastic damping (that is a high, or at least medium, Loss Tangent). The fibres (1) and thermoplastic material (2) are mixed, or compounded, by the material supplier and the material for the jacket (3) provided in granular form to the extrusion contractor. The manufacture of the jacket (3) is undertaken by normal extrusion processing.
