摘要： PURPOSE:To obtain a natural marble grain molded body, by a method wherein resin concrete containing a specific amount of a thickened thermosetting resin and aggregate is applied to the surface of a male mold to which gel coat is applied and, after curing, a female mold having a backing layer of a fiber material applied thereto is set to inject the resin concrete in the molds. CONSTITUTION:Resin concrete 1 containing 100 pts.wt. of a thickened thermosetting resin and 30-500 pts.wt. of aggregate having a particle size of 0.1-15 mm is uniformly applied to the surface of a male mold to which gel coat is applied in a thickness of 0.2-10mm and, after curing, a female mold having a backing layer reinforced by a fiber material applied thereto is set and resin concrete 2 the same as or different from the resin concrete 1 is injected in the molds to be cured. Each of the resin concretes 1, 2 is based on the thermosetting resin and compounded with aggregate composed of a natural stone consisting of white and black stones. Further, as the resin concrete 2, relatively low viscosity one is used. By this method, even when a molded body having a vertical surface such as a bathtub is prepared, the resin concrete can be cured while the stone is naturally dispersed.

摘要： PURPOSE:To harden in the state of natural dispersion without disarrayed pattern generated by sedimentation of aggregates by forming a gel coat layer as a first layer, a transparent FRP layer as a second layer constituted by glass fiber or a non-woven cloth impregnated with thermosetting resin, resin concrete of opaque granite feeling as a third layer and an FRP backup layer as a fourth layer. CONSTITUTION:A transparent gel coat layer as a first layer and a transparent FRP layer as a second layer constituted of 30g - 600g/m glass fiber or a non- woven cloth impregnated with thermosetting resin are formed successively on the surface of a first mold controlling one surface of a molded material. On the other hand, an FRP backup layer as a fourth layer is formed on the surface of a second mold controlling the other surface of the molded material. Then, resin concrete having thixotropy as a third layer containing 100 pts. wt. of synthetic resin and 10 - 300 pts. wt. of aggregates of 0.3 - 5mm size having two colors or more is injected into a space controlled by the first and second molds. The aggregates are not separated during molding by said process, and natural pattern can be provided.
