Abstract: A method for the production of a fiber-reinforced resin compound. The method comprises spraying onto a suitable substrate from three respectively different nozzles:1. an unsaturated polyester resin composition having a viscosity of about 3000 to 15000 Cps at 25.degree.C;2. a fiber-reinforcing material and3. a thickening agent of magnesium oxide, magnesium hydroxide, calcium oxide, calcium hydroxide or beryllium oxide suspended in a liquid polyester resin or a mixture of a liquid polyester resin and styrene, the weight of (1):(2):(3) being 100:20-55:3-30. The individual streams of (1), (2) and (3) intersect one another after exiting from said nozzles and prior to contacting said substrate to form one stream. The method can give a fiber reinforced resin compound having a strength equivalent to or more that of (sheet molding compound) and is simple in operation and can be carried out at a cost equivalent to or less than that bulk molding compound.
