Abstract

PURPOSE: To reduce substantially a developed noise toward inside and the outside of the vehicle by a method wherein a moldings thermally formed by a laminate comprising a bulky nonwoven cloth and a synthetic fiber frise is mounted within an engine room.
CONSTITUTION: A molding described hereinafter is mounted on the metal work parts such as a wheel housing and a dashpanel within an engine room and/or a base material having a sound absorption. In other words, the molding is thermally formed by a laminate comprising a bulky nowoven cloth and a synthetic fiber frise with a number of optional shape of protrusions, where the height of the protrusions above the flat surface is 5W400m/m, and the air stream resistance at the top of the protrusions gives 30W300c.g.s.rayls. Said synthetic fiber frise gives a bulk density of 4×10-4W8×10-2g/cm2, which is consisting of 5W200wt. of thermoplastic resin and/or thermosetting resin against synthetic resin weight of 100wt.
