1. MULTILAYER COMPOSITE part, it comprises following layers:

  • I. the ground floor (layer I) being made up of the moulding compound of the following component comprising at least 40 weight %;

    1) partially aromatic copolyamides of 60 to 95 weight portions, it is by derived from alpha) and monomeric unit β

    ) constitute;

    α

    ) the combination of the hexamethylene diamine of 30 to 90 moles of % and terephthalic acid (TPA)β

    ) the hexamethylene diamine of 70 to 10 moles of % and the combination of linear aliphatic dicarboxylic acids with 8 to 19 carbon atoms;

    Wherein said mole of % value is based on α

    ) and summation meter β

    ), and wherein most 20% hexamethylene diamine can be by equivalentOther diamines substitute and/or wherein most 20% terephthalic acid (TPA) can be by other aromatic dicarboxylic acids of equivalent and/or 1,4-ringHexane dicarboxylic acid substitute and/or wherein most 20% the repetitive being made up of hexamethylene diamine and linear aliphatic dicarboxylic acidsCan be substituted by the unit derived from the lactams with 6 to 12 carbon atoms and/or omega-amino carboxylic acid of equivalent,2) olefin copolymer of 40 to 5 weight portions is as impact modifier,Wherein

         1) and

         2) weight portion add up to 100;

    WithII. the second layer (layer II) being made up of the moulding compound of the mixture of the following component comprising at least 60 weight %;

    1) 75 to 100 weight portions partially aromatic copolyamides and2) olefin copolymer of 25 to 0 weight portions is as impact modifierCondition is in the moulding compound of layer II, component

         1) and

         2) mixture comprise as little as few 5 weight portions in the moulding compound than layer IOlefin copolymer.
