Underbody trim part for a road vehicle comprising a porous fibrous carrier layer, the trim part featuring a longitudinal direction to be aligned with the direction of travel of the road vehicle when the part is in use and further comprising an embossed foil locally bonded to the porous fibrous carrier layer, wherein the bending stiffness of the embossed foil is at least 10% of the bending stiffness of the porous fibrous carrier layer, in at least the longitudinal direction. The trim part is particularly suited to be used as an underbody liner for a vehicle. However, it may be used also as an under-engine liner or as a wheel-house outer liner.
