The invention provides a lightweight vehicle flooring assembly, wherein a carrier layer ( ) has a layered structure. This structure comprises a honeycomb-like core layer ( ) which can be made of a suitably impregnated cardboard material and which is connected on both sides to a stiffening layer ( ). The inner stiffening layer ( ) is made of an SMC-material, whilst the outer stiffening layer ( ) is made of a needled, preferably open-celled or porous nonwoven, also suitably impregnated against humidity and dirt. The structure of the carrier layer ( ) and, in particular, the sequence of the layers: skin, honeycomb structure, nonwoven is of particular significance for the mechanical stability of the carrier layer ( ). The carrier layer ( ) is provided with an inner and an outer lining, the inner lining comprising a PU-foam spring layer ( ) and a rubber or latex mass layer ( ). These inner and outer linings, by choice of suitable materials and configurations, can provide acoustically absorbent insulation systems for the vehicle flooring assembly.
