<p>The invention provides a lightweight vehicle flooring assembly, wherein a carrier layer (1) has a layered structure. This structure comprises a honeycomb-like core layer (7) which can be made of a suitably impregnated cardboard material and which is connected on both sides to a stiffening laye r (8, 9). The inner stiffening layer (8) is made of an SMC-material, whilst th e outer stiffening layer (9) is made of a needled, preferably open-celled or porous nonwoven, also suitably impregnated against humidity and dirt. The structure of the carrier layer (1) and, in particular, the sequence of the layers: skin, honeycomb structure, nonwoven is of particular significance fo r the mechanical stability of the carrier layer (1). The carrier layer (1) is provided with an inner and an outer lining, the inner lining comprising a PU - foam spring layer (10) and a rubber or latex mass layer (11). These inner an d outer linings, by choice of suitable materials and configurations, can provi de acoustically absorbent insulation systems for the vehicle flooring assembly.</p> |
