MIL-PRF-23653D, PERFORMANCE SPECIFICATION: PLASTIC TILES, VIBRATION DAMPING (05-NOV-2009) [SUPERSEDING MIL-P-23653]

MIL-PRF-23653D, PERFORMANCE SPECIFICATION: PLASTIC TILES, VIBRATION DAMPING (05-NOV-2009) [SUPERSEDING MIL-P-23653]., This specification covers four classes of flexible, water and fuel-resistant, fire-retardant plastic tiles for damping the flexural vibration of shipboard metal structures. This material is intended to be installed in accordance with the procedures of MIL-STD-2148 for use as a vibration damping material for steel plates in free-layer, restrained-layer and constrained-layer configurations. The choice of tile class and weight depends respectively on the temperature and thickness of the steel plating to be damped. For toxicity reasons this material should not be used at temperatures over 200.0 deg F (93.3 deg C).
