Abstract
A method of protecting acoustic and damping tiles from fire damage by placing a fire barrier silicone foam sheet on the inner surface of a mold, mounting the mold at a selected distance from the surface of a hull of a vessel with the fiberglass cloth side of the silicone foam sheet facing the hull and spaced therefrom, injecting a polyurethane foam into the space between the hull surface and the silicone foam sheet, curing the polyurethane foam, and removing the mold. The porosity of the polyurethane foam is imparted by incorporation of 5-50% by volume of Saran.RTM. microspheres.
