Motor vehicle`s two-layered composite part e.g. instrument panel, manufacturing method, involves producing carrier from fibre reinforced thermoplastic synthetic material and overspraying carrier with synthetic material without fibre parts

摘要

The method involves producing a carrier (3) from a fibre reinforced thermoplastic synthetic material by an injection moulding process. The carrier is oversprayed with a thermoplastic synthetic material without fibre parts by the injection moulding process for forming a top layer (7) in a cavity (5). The cavity exhibits a grain (6) at its surface such that another grain is produced in a surface of the top layer. Polypropylene-long glass fibre, styrol-maleic anhydride glass fibre, polycarbonate acrylonitrile-butadiene-styrol-copolymer glass fibre, acrylonitrile butadiene styrene-long glass fibre and/or polybutylene-terephthalate glass fibre is used as fibre reinforced thermoplastic synthetic material for manufacturing the carrier. Polypropylene talcum, polypropylene-ethylene-propylene-diene-rubber-talcum reinforced and/or thermoplastic elastomer is used as thermoplastic synthetic material for manufacturing the top layer. An independent claim is also included for an interior lining part e.g. instrument panel, for a motor vehicle.
