Acoustic, Thermal and Fire Insulation System

In recent years, significant strides have vastly improved the potential for spray on insulation systems that will help to abate airborne noise on Surface Ships. The optimal insulation will provide high acoustic absorption, airborne transmission loss and structural damping along with the requisite thermal/fire/condensation protection. Our objective is to exhibit improved acoustic characteristics through a liquid ceramic thermal insulation that provides NAVSEA approved condensation control. Combine this product with a tested fire retardant product that also displays damping capabilities. These products will produce a multi-modal or composite layered liquid applied barrier. This coating combination is safe, light weight and produces very little smoke. The concept will use proven ceramic micro-sphere technology that we have developed and designed over a 14 year period. The blending of micro spheres in a safe, light weight waterborne matrix has been accepted for use by industry and manufacturing in a wide array of circumstances. TECH 21 research will investigate how these products can be combined for maximum results. The conclusion will yield a method of blending and installation that will reduce handling, weight and installation costs. We will explore the incorporation of this system into the N98-092 JERICHO program and SNAME's Design Guide 3.37.
