Abstract

PURPOSE: An electrical insulating composite cast material having improved impact strength, wherein a fiber reinforced layer treated by an ultraviolet-curing resin is embedded in a cast or impregnated resin part and firmly bonded to it.
CONSTITUTION: A fiber reinforced sheet, e.g., a sheet of cloth or paper is treated by an ultraviolet-curing resin varnish obtained from a blend of (A) thermosetting resin varnish prepared by blending an epoxy resin having two or more oxirane rings in a molecule with a curing agent and (B) 5W90 phr of photo-setting resin varnish obtained by adding 0.01W5 wt% of a photosensitizer to a prepolymer having two or more polymerizable unsaturated groups. The resulting fiber reinforced sheet treated by ultraviolet-curing resin varnish is wound around the wooden mold 3 which is to be rotated in the arrow direction round the central axis 3a and th resin is cured by irradiation of ultraviolet light to form the fiber reinforced layer 2. The layer 2 is removed from the wooden mold 3 and set in a mold for casting. A casting resin is injected into the mold and cured under heating to give a cast article wherein the fiber reinforced layer 2 is embedded in the resin part 1.
