Title:
SOUND ABSORPTION PANEL
Document Type and Number:
WIPO Patent Application WO/2012/111720
Kind Code:
A1
Abstract:
Sound absorbency is imparted on a panel, which has increased strength and rigidity, by laminating a foam resin that is not naturally permeable and does not absorb sound, and surface sheets that are not naturally permeable and do not absorb sound. A sound absorption panel (1), obtained by laminating a foam resin (20) comprising closed cells and aluminum alloy sheets (10) (metal sheets), has a plurality of holes (30) formed therein, which penetrate the foam resin (20) and the aluminum alloy sheets (10) in the thickness direction. The holes (30) are formed by forcing a needle (40) (hole-forming means) through the foam resin (20) and the aluminum alloy sheets (10).
