ADC-224 is a mid-temperature skin damping composite of 0.25" thick damping foam fixed with 0.005" thick aluminum foil and backed with pressure sensitive adhesive. Used in aircraft for weight efficient damping and to reduce radiated noise. Meets FAR 25.853 (A) for fire resistance. Furnished in 27" x 48"
Q: Will this E-A-R Composite Damping Foam be a suitable insulator for a composite experimental aircraft? I'm between this and the super sound proofing.
Yes, both are good quality products and would work well with composites.
Q: It is important to distinguish between material to dampen vibrations versus material to absorb sound waves. Your answer to the question comparing this to Super Sound proofing is misleading. This product is used to dampen vibration while the super sound proofing is for absorbing sound. Both are needed especially in aluminum airplanes where the aluminum sheet might vibrate.
