Composite material comprising polyurethane and at least one thermo-plastic plastics material, a process for the production thereof and the use thereof in motor vehicles

摘要

A composite material is described which comprises at least two layers of different plastics materials which are directly bonded to each other, wherein ;A) one layer of the composite comprises polyurethane, and ;B) a layer of the composite which is directly bonded to layer A) comprises a thermoplastic plastics material which is different from the material which layer A) comprises, ;wherein layer A) contains homogeneously distributed particles, which are at least coated with a thermoplastic plastics material which is different from the material comprising layer A), and which have a particle size of # 50 nm, wherein the total surface area of the particles corresponds at least to the extent of the total interface between layers A) and B). ;A process for the production of these composites is also described, as is the use of these composites in motor vehicle construction.
