SOUND ABSORPTION MATERIAL, SOUND ABSORPTION MOLDING, AND MANUFACTURING METHOD OF SOUND ABSORPTION MOLDING

摘要

To provide a sound absorption material, a sound absorption molding, and a manufacturing method of the sound absorption molding capable of suppressing deterioration of releasability without lowering sound absorbing performance and working efficiency.SOLUTION: A sound absorbing material 10 is composed of a base material 11 made of a porous material impregnated with a thermosetting resin, and a skin material 12 made of a nonwoven fabric having an adhesive surface 12A made of an adhesive powder provided on one side of the base material 11 side. The nonwoven fabric in the skin material contains polyester fibers in an amount of 80 mass% or more and a mass per unit area of 20 to 150 g/m, and the sound absorption molding is obtained by hot press molding the sound absorbing material 10 into a predetermined shape.SELECTED DRAWING: Figure 1
