Abstract
PURPOSE: To produce a synthetic resin-formed product which reduces appearance of fiber marks in FRP and has superior properties of keeping warmth and durability and good appearance by inserting foamed synthetic resin layer into the gap between the gel coat layer of front surface of a male mold and FRP reinforcement layer of back surface of a female mold.
CONSTITUTION: For instance, in the case of forming bath, a forming mold 10 composed of a female mold 11 and a male mold 12 is used, and gel coat compound 13 is coated with desirable thickness of 0.2W0.5mm on the mold surface of the male mold. Then, FRP reinforcement material 14 is piled up on the mold surface of the female mold 11. After two molds are firmly fixed, foamed synthetic resin solution 16 (e.g. foamed polyurethane resin solution 16 with 0.4W0.8 specific gravity is desirable) is poured into the cavity 15 and hardened with foaming and thus, the objective foamed product may be obtained.
EFFECT: The product has no swelling up of blow holes by its contraction with hot water, and further it has good heat-insulation property and obtains light structure as compared with its thickness.
