Title:
部分芳香族ポリアミドからなる層を有する多層複合材料
Document Type and Number:
Japanese Patent JP6671200
Kind Code:
B2
Abstract:
A multilayer composite containing the following layers: 1. 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 a mixture of the following components: 1) 75 to 100 parts by wt. of a partly aromatic copolyamide and 2) 25 to 0 parts by wt. of an olefinic copolymer as impact modifier with the proviso that in the moulding compound of layer II the mixture of components 1) and 2) comprises at least 5 fewer parts by wt, of olefinic copolymer than in the moulding compound of layer I, has a high heat distortion temperature, a very good impact resistance, a high elongation at break and good layer adhesion.
