Smooth Compliant Antifoulant Coatings.

Abstract

Fiber reinforced composites provide a wide array of structural and acoustic properties. The composites may be isotropic or extremely anisotropic, and offer considerable flexibility for designing underwater acoustic sensor flow noise outer decouplers. Compliant layers appear to be effective in suppressing flow noise; however, effectiveness diminishes with depth, in part because of material compressibility and distortions caused by own ship's speed. Composite materials can be fabricated with high strength and modulus to maintain shape under severe loads to eliminate erratic acoustic performance caused by outer decoupler distortion. (Author)
