Technical Data
Product Description
Typical Damping
Properties
January, 2012
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.
