TILE, RUBBER VIBRATION DAMPING, TYPE V
Additional Comments: RENUMBERED AS MIL-DTL-24487
Class 1 tile is intended to damp vibrations in steel plates 0.5 inch thick or less. The grooved face of the tile is bonded with epoxy resin to the steel plate. The grooved face enables the tile to conform easily to a curved surface. This tile may be used in flooded spaces. If installed in submarine ballast tanks, the tile is restrained with a glass reinforced plastic sheet, steel studs, nuts, and washers, in accordance with MIL-STD-2148.
Class 2 tile is intended to damp vibrations in a steel plate greater than 0.5 inch (1.3 cm) thick, but less than 0.75 inch (1.9 cm) thick. The grooved face of the tile is bonded with epoxy resin to the steel plate. The grooved face enables the tile to conform easily to a curved surface. This tile is normally constrained by a 0.125 inch (0.32 cm) thick aluminum sheet bonded to the tile with the epoxy adhesive. The tile is not acquired with the aluminum sheet already bonded to it. This assembly is not used in flooded spaces unless the aluminum constraining layer is removed. The tile and aluminum constraining layers are installed in accordance with MIL-STD-2148.
