Abstract:
The invention relates to a process for the production of a composite component, comprising a) a support of a thermoplastic composition, and b) at least one polyurethane layer in direct contact with the support. The process involves (i) in a first process step the melt of the thermoplastic composition is injected into a first mould cavity and is subsequently cooled, the thermoplastic composition comprising: A) 65.0 to 90.0 parts by wt., based on the sum of components A and B, of at least one polymer chosen from the group of aromatic polycarbonates, aromatic polyester carbonates and aromatic polyesters, B) 10.0 to 35.0 parts by wt., based on the sum of components A and B, of an optionally rubber-modified vinyl (co)polymer and C) 0 to 30.0 parts by wt., based on the sum of components A to C, of at least one commercially available polymer additive, And (ii) in a second process step the cavity of the injection mould is enlarged and a gap is thereby generated, and (iii) in the third process step a reactive polyurethane raw material mixture comprising at least one polyisocyanate component, at least one polyfunctional H-active compound, and optionally at least one polyurethane additive and/or process auxiliary substance is injected into the gap resulting in this way between the thermoplastic component and the mould surface of the enlarged cavity, the polyurethane raw material mixture polymerizing completely in contact with the surface of the thermoplastic support to give a compact polyurethane layer or to give a polyurethane foam layer. And (iv) in a fourth process step the composite component is removed from the mould cavity. Preferably the process steps following one another directly.
