An underbody trim component for a road vehicle, comprising a porous fibrous carrier layer, the trim component being characterized in that the longitudinal direction of the component is aligned with the direction of travel of the road vehicle when the component is in use, and further comprising an embossed foil locally bonded to the porous fibrous carrier layer, wherein the flexural rigidity of the embossed foil at least in the longitudinal direction is at least 10% of the flexural rigidity of the porous fibrous carrier layer. The trim part is particularly suitable for use as an underbody liner for a vehicle. However, it can also be used as an engine underliner or a wheel casing outer liner. 一种用于道路车辆的车底装饰部件，其包括多孔纤维载体层，该装饰部件的特征在于当该部件在使用时其纵向方向与道路车辆的行驶方向对齐，并且还包括局部地粘结到多孔纤维载体层的压花箔，其中压花箔至少在纵向方向上的弯曲刚度是多孔纤维载体层的弯曲刚度的至少10％。装饰部件特别适合用作车辆的车底衬垫。然而，它也可以用作发动机下衬垫或轮罩外部衬垫。
