MULTI-PURPOSE, ALUMINUM FOAM-BASED SOUNDPROOF PANEL

摘要

There is disclosed a multipurpose, aluminum foam-based soundproof panel (400b) which comprises at least one aluminum foam panel (10) with a plurality of open pores. The open pores are formed from the closed pores within a mass of aluminum foam by rolling the aluminum foam into a panel. The aluminum foam panel (10) with a plurality of open pores is bonded with or coated with fibrils (120), a perforated thin plate, a finish material, paint, a sound-absorbing member or noise insulator (440) or a honeycomb structure on at least one surface or impressed with a pattern on one surface or has resonance hollows therein. In addition to being used as ultralight, construction finish materials with high durability and strength in the edifices or facilities which require noise insulation, the soundproof panel (400b) is superior in sound absorption performance and easy to handle. Furthermore, the panel allows a construction work to be easily executed.
