Title (EN) VEHICULAR SOUND ABSORBING MEMBER
(FR) ÉLÉMENT D'ABSORPTION ACOUSTIQUE DE VÉHICULE
Abstract:
(EN) A vehicular member that has an excellent sound absorption coefficient when, for example, the vehicular member is used as a sound absorbing material for a vehicle exterior cladding member (such as a fender liner). The vehicular member (21) includes a non-woven fabric web. A loss factor of the non-woven fabric web at 20C and 10 Hz is preferably not less than about 0.07, and a bending rigidity of the non-woven fabric web is preferably not less than about 0.5 N/50 mm.
(FR) L'invention concerne un élément de véhicule qui a un excellent coefficient d'absorption acoustique quand, par exemple, l'élément de véhicule est utilisé en tant que matériau d'absorption acoustique pour un élément de revêtement extérieur de véhicule (tel qu'une doublure d'aile). L'élément de véhicule (21) comprend une bande de tissu non tissé. Un facteur de perte de la bande de tissu non tissé à 20°C et 10 Hz est de préférence supérieur ou égal à environ 0,07, et une rigidité à la flexion de la bande de tissu non tissé n'est de préférence pas inférieure à environ 0,5 N/50 mm.
