Abstract
Se proporciona un material fonoabsorbente para un vehículo, capaz de producir de manera estable el desempeño de absorción del sonido deseado mientras se reduce el peso del material que absorbe el sonido para un vehículo. El material fonoabsorbente para un vehículo, de la presente invención, tiene una estructura multicapa, que incluye: una capa central 10 en donde las celdas tubulares 20 se disponen en una pluralidad de filas; y una capa 40 de película de resina que bloquea el flujo de aire adherida a una superficie de la capa central. Las celdas tienen superficies cerradas 21 y extremos abiertos 22 en filas alternas en los extremos de las celdas en una superficie de la capa central. En los extremos de las celdas en la otra superficie de la capa central, las celdas tienen extremos abiertos 22 en las filas en donde las celdas tienen las superficies cerradas en los extremos de las celdas en la superficie, y tienen superficies cerradas 21 en las filas en donde las celdas tienen los extremos abiertos en los extremos de las celdas en la superficie. Los extremos abiertos 22 permiten que los espacios internos de las celdas 20 se encuentren en comunicación con el exterior. La relación entre el módulo de Young E (MPa) de la capa de película de resina que bloquea el flujo de aire 40 y la densidad superficial M (g/m2) de la estructura de capas en el primer lado de la capa de película de resina que bloquea el flujo de aire 40 con respecto a la capa central 10 es 0.5 < E/M < 21.
