Provided is a multilayered container including a polyester layer containing a thermoplastic polyester resin (X) and a polyamide layer containing a polyamide resin (Y), wherein the polyester layer is an innermost layer, and the polyamide layer is an intermediate layer. The polyamide resin (Y) has a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid. At least 70 mol % of the constituent units derived from a diamine are a constituent unit derived from a xylylenediamine, and at least 70 mol % of the constituent units derived from a dicarboxylic acid are a constituent unit derived from an α,ω-linear aliphatic dicarboxylic acid having from 4 to 20 carbons. When an overall thickness is 100%, the polyamide layer is present from a position of 5 to 35% from an inner surface, and a thickness of the polyamide layer is from 1 to 15%.

The disclosed composite structure provides a reinforced thermoplastic polymer composite part with a high-quality surface finish. This may be used as a vehicle part or body panel, such as an interior vehicle part or exterior body panel. Additionally, the surface finish may be coloured, such that the surface does not need to be painted or wrapped to achieve a desired surface colour, and the surface may protect inner layers from UV radiation, either by virtue of the material of the surface itself, or the incorporation of a UV-absorbing additive. Specifically, the disclosed composite structure comprises a structural layer comprising reinforcing fibres, such as glass or carbon fibres, and a thermoplastic body polymer. The structure further comprises a surface layer providing a surface finish to the composite structure, the surface layer comprising a thermoplastic surface polymer substantially free from reinforcing fibres.

The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.
