The invention relates to a multilayer composite comprising a polyester layer. The multilayer composite contains the following layers: I. a first layer (layer I) of a moulding compound containing at least 40 wt. % of the following components: 1) 60 to 99 parts by wt. of a copolyamide based on hexamethylenediamine, terephthalic acid and an aliphatic dicarboxylic acid having 8 to 19 carbon atoms and 2) 40 to 1 parts by wt. of an olefinic copolymer as impact modifier, wherein the parts by wt. of 1) and 2) sum to 100; and II. a second layer (layer II) of a moulding compound containing at least 60 wt. % of thermoplastic polyester, has a high heat distortion temperature, a very good impact resistance, a high elongation at break and good layer adhesion. 本发明涉及包含聚酯层的多层复合件。其包含下列层并具有高的热变形温度、极好的抗冲强度、高的断裂伸长率和良好的层粘附：I.由包含至少40重量%的下列组分的模塑料制成的第层（层I）：1)60至99重量份的基于六亚甲基二胺、对苯二甲酸和具有8至19个碳原子的脂族二羧酸的共聚酰胺2)40至1重量份的烯烃共聚物作为抗冲改性剂，其中1)和2)的重量份合计为100；和II.由模塑料制成的第二层（层II），所述模塑料的至少60重量%由热塑性聚酯构成。
