Comparative Sound Absorption and Thermal Insulation Properties of Compound Fabrics

Abstract:

The compound fabrics comprised of double layers of nonwovens and carbon fabrics were prepared by needle-punching and thermal bonding techniques. The thermal bonding and number of layers effect on thermal insulating and sound absorbing property have been discussed. The resulting compound fabrics have thermal conductivity decreases to 0.02 W/(m*K) for single layer of thermo-bonded compound fabrics and sound-absorbing coefficient reaches to 0.848 at 4000 Hz for 3-layer un-thermo-bonded fabrics .
