  • Multilayer dash isolation pad having superior formability and sound absorption performance
    Patent number: 9715871
    Abstract: The present invention provides a multilayer dash isolation pad having superior formability and sound absorption performance. The multilayer dash isolation pad includes a decoupler and a sound absorption and insulation layer. The decoupler is a soft felt manufactured from urethane foam or octalobal cross-section fiber, and the sound absorption and insulation layer includes a compressed felt manufactured from octalobal cross-section fibers. In particular, the shape factor (?) of the octalobal cross-section fiber is 2.0 to 2.7. Particularly, the multilayer dash isolation pad according to the present invention does not decrease thickness or be contracted upon press molding after pre-heating felt, such that superior formability in components can be obtained and a sound absorption coefficient may be enhanced without increase in the weights and thicknesses of the decoupler and the sound absorption and insulation layer.

  • MULTILAYER DASH ISOLATION PAD HAVING SUPERIOR FORMABILITY AND SOUND ABSORPTION PERFORMANCE
    Publication number: 20170011729
    Abstract: The present invention provides a multilayer dash isolation pad having superior formability and sound absorption performance. The multilayer dash isolation pad includes a decoupler and a sound absorption and insulation layer. The decoupler is a soft felt manufactured from urethane foam or octalobal cross-section fiber, and the sound absorption and insulation layer includes a compressed felt manufactured from octalobal cross-section fibers. In particular, the shape factor (a) of the octalobal cross-section fiber is 2.0 to 2.7. Particularly, the multilayer dash isolation pad according to the present invention does not decrease thickness or be contracted upon press molding after pre-heating felt, such that superior formability in components can be obtained and a sound absorption coefficient may be enhanced without increase in the weights and thicknesses of the decoupler and the sound absorption and insulation layer.
