| Soundproof effect of nanoreinforced polymer composites
Yeon-Jun Kang
The Journal of Mechanical Science and Technology, vol. 22, no. 8, pp.1468-1474, 2008
Abstract : In this paper, the effects of soundproofing by polymer and carbon-nanotube (CNT) composites were investigated.
The specimens for sound insulation measurement were fabricated with Acrylonitrile Butadiene Styrene (ABS)/CNT
composites. Tests showed that sound transmission loss of ABS/CNT 15 vol.% composite was higher by 21.7% (4.1
dB) than that of pure ABS specimen at a frequency of 3400 Hz. It was found that the principal factor influencing the
improvement of sound insulations of ABS/CNT composites was increased stiffness by CNT additives. To demonstrate
the practical applicability of polymer/CNT composites, tests were conducted for the reduction of operational noise
from mechanical relay.
