ABSTRACT:
In a moulding process for producing automobile parts, the female part (1) of a two part mould is sprayed with a metal such as stainless steel, tin, nickel-tin, copper or zinc. A thermal expansion compensation layer (3) is laid on the sprayed mould surface (1) and a layer of a resin impregnated fibrous material is applied thereto. The resultant assembly is cured and then removed from the female part of the mould or removed from the mould and then cured. The metal surface (2) of the composite part may be subject to further treatment such as polishing, coating and painting, or a combination of these. “Windows” may be produced by leaving areas of the mould part unsprayed with metal. In this way panels for lights, aerials or proximity sensors may be integrally formed.
