January, 2016 3M™ Damping Aluminum Foam Sheet 4014 Product Description 3M™ Damping Aluminum Foam Sheet 4014 is an open-cell polyurethane foam with an aluminum constraining layer on one side and a pressure sensitive adhesive on the opposite side to facilitate attachment to the surface of the vibrating panel. The adhesive is protected by an easy-release liner. How it works: Strain energy from the vibrating panel is introduced into the viscoelastic foam. The strain in the foam is in shear as a result of the aluminum constraining layer. The viscous portion of the response of viscoelastic foam results in mechanical energy being dissipated to negligible heat. This energy dissipation results in (1) attenuated amplitudes of vibration when systems are being continuously excited at frequencies which match their natural frequencies, or (2) more rapid decay in systems that are freely oscillating at their natural frequencies as a result of a momentary excitation such as an impact. Product Features

  • Excellent damping per pound of material used and installed cost ratio.
  • Easy to apply – only hand pressure required.
  • Good thermal insulator and heat reector.
  • Excellent moisture resistance, aging properties and fatigue resistance.
  • Meets Federal Air Regulation Flammability Specications for acoustical insulation materials (FAR Section 25.853, Paragraph B).

3M™ Damping Aluminum Foam Sheet 4014 Technical Information Note The following technical information and data should be considered representative or typical only and should not be used for specication purposes. Typical Physical Properties Property Values Thickness 6.35 mm 250 mil Weight 1.32 kg/m² 0.27 lb/ft² Moisture Resistance Less than 0.25% weight gain (When conditioned at 150°F/67°C and 100% RH for one week). Typical Damping Properties The gure below illustrates the damping measured on 2 of the bending modes of a stainless steel cantilever beam when 3M damping aluminum foam sheet 4014 is attached to the surface of the beam. The damping is measured as a function of temperature and is compared to an untreated beam. This damping was determined by the half power band width technique on frequency response functions measured with a Fast Fourier Transform Analyzer.

3M™ Damping Aluminum Foam Sheet 4014 Electrical and Thermal Properties Property Values Thermal Conductivity 0.069 W/m/°C 0.48 (btu-in)/(h-ft²-°F) Certications/Standards Federal Aviation Regulations, FAR 25.853 3M™ Damping Aluminum Foam Sheet 4014 FAR (Federal Air Regulation) Section 25.853 Compartment Interiors We have classied our 3M damping aluminum foam sheet 4014 construction within paragraph (B) of the subject FAR Section as it is included in the class of acoustical insulation materials. As such, it must be self extinguishing when tested vertically in accordance with the applicable portions of Appendix F (Acceptable Test Procedure for showing compliance 25.853). Specimen samples of 3M damping aluminum foam sheet 4014 were prepared in accordance with paragraph (B) of Appendix F. “Materials must be tested either as a section cut from a fabricated part as installed in the airplane or as a specimen simulating a cut section.” Samples of 3M damping aluminum foam sheet 4014 (3 in x 12 in) were applied to 20-mil aluminum panels of the same size to meet this requirement. The apparatus used to conduct this testing was as specied in Paragraph (C) of Appendix F. Handling/Application Information Application Ideas

  • Reduce resonant noise, vibration and fatigue in metal, plastic panels and support structures.
  • Almost anywhere plastic or metal contact with materials that can result in potentially damaging vibration.

3M™ Damping Aluminum Foam Sheet 4014 Handling/Application Information (continued) Application Techniques 3M™ Damping Aluminum Foam Sheet 4014 contains an aggressive pressure sensitive adhesive to facilitate bonding to the surface of the structure. Best results are obtained when applied at temperatures above 50°F (10°C) on a clean, dry surface (free of oil, wax, dust, rust, etc.) and the bond is continuous (void-free) throughout the interface between 3M damping aluminum foam sheet 4014 and the structure. For best results apply as follows: 1. Clean metal surface of structure with appropriate solvent for removing any surface contaminants such as processing oils or waxes. Note: When using solvents, be sure to extinguish ignitions sources and follow the manufacturer’s precautions and directions for use when handling such materials. 2. Wipe the clean surface of the structure to complete dryness with a clean, dry lint free cloth. Note: Steps 1 and 2 should be repeated until the used drying cloth is clean (no more residue appears on the cloth after wiping). 3. Remove the protection liner. 4. Place one edge on the surface of the structure and press into place with nger pressure. Lower the rest of the foam piece into place while applying nger pressure on the bond line as it progresses across the surface of the structure. This method of application will minimize voids in the pressure sensitive bond. Storage and Shelf Life To obtain best performance, use this product within 24 months from date of manufacture.
