<P>PROBLEM TO BE SOLVED: To create a damping material which attains weight saving than a conventional type polymer system damping material, and at the same time, improves a damping performance, and is excellent in cost reduction, design properties, and moldability. <P>SOLUTION: The three layers are compounded and integrated; an adhesive layer (damping layer) which applies an adhesion function to a substrate to be damped, being as a first layer; a compressed porous body layer of polyester fiber system nonwoven fabric, being as a second layer; and a skin layer of polyester system spunbond fabric which constrains the compressed porous body layer, being as a third layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
