Automotive interior materials and manufacturing method thereof, and automotive interior materials laminated sheet for

摘要

PROBLEM TO BE SOLVED: To provide a laminated sheet for an automobile interior material capable of being molded to a desired shape while maintaining excellent sound-absorption performance.;SOLUTION: The laminated sheet A for the automobile interior material is constituted so that a hole part 2 opened to a surface is formed on one surface of a modified polyphenylene ether based resin foaming sheet 1 having an open cell ratio of 50% or higher and a surface sheet 4 comprising a non-woven fiber comprising a form retaining fiber and a thermoplastic resin fiber is laminated/integrated on at least a hole part formation part 1a. Thereby, vibration energy of sound is smoothly induced to the open cell of the modified polyphenylene ether based resin foaming sheet 1 through the hole part and a cell wall of the open cell is vibrated. Thereby, the vibration energy is converted to heat energy and excellent sound-absorption property can be exhibited.;COPYRIGHT: (C)2005,JPO&NCIPI
