3M? Damping Foil 2552 consists of a room temperature pressure sensitive

viscoelastic polymer on a dead soft aluminum foil and is designed for application

to vibrating panels and support members. The combination of viscoelastic

polymer and an aluminum foil backing (a constrained layer damper, or CLD) has

proved to be a unique construction with exceptional ability to control resonant

vibrations in the temperature range of 32° to 140°F (0° to 60°C), with survivability

from -25° to 175°F (-32° to 80°C).

The high-energy dissipative polymer used in 3M damping foil 2552 can afford

excellent control of resonance-induced vibrations. When applied to a vibrating

structure, the polymer used in 3M damping foil 2552 converts vibration to negligible

heat. Vibration amplitudes and structure-borne noise can be consequentially reduced.

The performance of most damping devices is highly dependent on the interaction

between the device and the system to which it is applied. A constrained layer control

system is no different than a typical damping device and its ability to provide the

desired performance is affected by parameters other than temperature and frequency.

Namely the geometry, stiffness and the structure to which the control system is applied

will affect the performance.

The loss factor of a material is a dynamic property that can define damping

performance:

The following data are the results of 3M damping foil 2552 being tested per ASTM

E756-83. A sample was applied to a 8.0 inch by 0.5 inch by 0.06 inch steel beam.

The beam was tested over a temperature range of -40° to 140°F, in increments of

10°F. Beam modes 2 through 7 were monitored for system damping measurements.
