An insulator dash (20) installed on the interior side surface side of a dash panel (10), comprising a single sound absorbing layer (21) formed of a fiber assembly or a laminated assembly having light and soft skin layers (22,23,26,27,28) laminated on the surface of sound absorbing layer (21), wherein, since the reflected noise reflected from the inner surface of an instrument panel (40) is taken again from the front surface side into the sound absorbing layer (21) for sound absorption in addition to the sound absorbing and shielding performance of the insulator dash (20), the sound absorbing performance in the instrument panel (40) can be increased, whereby the weight can be reduced and a rise of sound pressure in the instrument panel (40) can be abolishing a conventional sound shielding layer so as to increase a silentness in a cabin.
A sound insulator for vehicle (20) which is installed at the interior side surface of a body panel (10), comprising a single sound absorbing layer (21) composed of a fibrous molding assembly;
A sound insulator for vehicle (20) which is installed at the interior side surface of a body panel (10), comprising a sound absorbing layer (21) made of a porous molding assembly formed in conformation with the surface features of the body panel (10) and a surface skin layer (27) integrally laminated to the sound absorbing layer (21) on the surface side of the sound absorbing layer (21);
A sound insulator for vehicle (20) which is installed at the interior side surface of a body panel (10), comprising:
A method for manufacturing a sound insulator for vehicle (20) comprising a sound absorbing layer (21), said sound absorbing layer being installed at the interior side surface of a body panel (10) and being formed in conformation with the features of the cabin-side surface of the body panel (10), and a surface skin layer (27) integrally laminated to the surface of the sound absorbing layer (21), the method comprising the steps of:
A method for manufacturing a sound insulator for vehicle, wherein the amount of the resin powder (P) to be sprayed on the heat-softened raw mat (M) is adjusted for each position thereof.
