ABSTRACT:
The invention relates to a method of manufacturing a metallized plastic reflector in which a layer of fibrous material is provided on the convex surface of a mold. The layer is then just saturated with a thermohardening synthetic resin, and after partial hardening, a metal layer is applied onto the partially hardened resin layer by means of a spraying process. A supporting layer of a fiber reinforced thermohardening synthetic resin is then provided on the metal layer and after hardening the reflector is finally removed from the mold.
