Document Type and Number:
WIPO Patent Application WO/2005/003422
Kind Code:
A1
Abstract:
A high-strength, lightweight fiber sheet exhibiting excellent acoustic absorption, and its molding. Fibers are admixed with thermally expanding granules to be formed into a sheet, and when the thermally expanding granules are thermally expanded by heating the sheet while regulating the thickness thereof, peripheral fibers are compressed and a high-density fiber sheet is obtained.
