Abstract

The present invention relates to a composite material having improved thermal and mechanical properties which comprises at least: PA0 (I) an outer layer made of a molding composition based on polyvinylidene fluoride, and PA0 (II) an intermediate layer which neighbors the inner layer and is made of a molding composition based on a mixture of (a) from 40-90% by weight a polyamide and (b) from 60-10% by weight a polyglutarimide, wherein the two layers (I) and (II) are adhesively bonded to one another.
