| 摘要 |
A vehicle trim component has a surface portion forming a tactile interface, the component comprising a thermally conductive polymer composition (1, figure 2) that forms, or is in thermal contact with a material forming, the surface portion. The surface portion may be at least partially coated with a metallic finish or with metal, which may be deposited by vapour deposition, such as sputter coating, or by electroplating. The surface portion is preferably at least partially coated by two or more layers of metal, which may be successive layers of copper (2), semi-bright nickel, bright nickel (3) and chromium (4). The polymer composition may comprise acrylonitrile butadiene styrene (ABS), polycarbonate (PC), epoxy resin, polyetherimide (PEI), polyphenylene sulphide (PPS) or nylon, and is preferably a blend of two or more polymers. The polymer may contain carbon graphite particles, carbon fibres, or carbon nano-fibres, nano-rods, nano-particles or nano-tubes, metal particles or metal nano particles. The component may be a handle, switch (5, figure 3), button (6), dial (7) or air vent (8). Also disclosed is a method of producing a vehicle trim component having the steps of injection moulding a thermally conductive polymer composition and depositing a metal coating.
