はきわめて困難であるという問題点があつた。 When producing interior products using FRP, the hand lay-up method, resin injection method, cold press method, etc. are used, but most of the molds used at that time are FRP molds. If the surface of the product is required to have high gloss, the surface of the FRP mold may be sufficiently polished to transfer that gloss to the product. On the other hand, if the surface of the product is required to be in a matte state, the surface of the FRP mold is made to have a matte state by making fine irregularities by blasting or other methods, and the surface of the FRP mold is not polished during molding. The unevenness is transferred to the product, but with this method, the fine unevenness on the surface of the FRP mold gradually wears away due to repeated mold polishing work, so the FRP
There was a problem in that the gloss state of the surface of the product manufactured by the mold gradually changed. Also,
When the FRP mold is large or has a complicated shape, there is a problem in that it is extremely difficult to uniformly form fine irregularities over the entire surface of the FRP mold using blasting methods.

である。 To make an FRP mold, first make a wooden mold for making the FRP mold, apply a mold release agent to its surface, dry it to form a mold release film, and apply gel coat (this gel coat) on top of it. will later become the mold side gel coat layer 3 (see Figure 2), and then
A glass mat cloth impregnated with a thermosetting resin such as polyester resin (this glass mat cloth will later become the mold side glass mat cloth 8).
See diagram. ) are laminated, reinforcing members are glued to the outside,
Remove the mold. FIG. 2 is an enlarged sectional view of section A in FIG. 1. A mold-side gel coat layer 3 is formed on the surface of the mold-side glass mat cloth 8 of the FRP mold 1. The reason for providing the gel coat layer 3 on the mold side is to give durability to the surface of the FRP mold 1 since glass mat/cloth is weak against friction, and because the surface of the glass mat/cloth 8 on the mold side has large irregularities, This is to give smoothness to the surface of mold 1.

成されているプロフイールｐを第３ｂ図に示す。 A mold release agent is applied to the surface of the gel coat layer 3 on the mold side of the FRP mold 1 and dried to form a mold release film 4. FIG. 3a is an explanatory diagram schematically showing a state in which the matting agent particles 7 are protruding from the surface 4a of the release coating 4. When an aqueous solution of polyvinyl alcohol is applied thinly to the surface of the gel coat layer 3, the water evaporates, so the thickness of the coating film becomes thinner by that amount, and after drying, it becomes a thin film of polyvinyl alcohol containing a large number of matting agent particles 7. A release film 4 is thus formed. By changing the size, amount, type, and solution concentration of the matting agent particles, the manner in which the matting agent particles 7 emerge (fine irregularities) can be selected as desired. The profile p formed by the matting agent particles 7 protruding from the surface 4a of the release coating 4 in FIG. 3a is shown in FIG. 3b.

製品２の表面に所定の艶消状態が付与される。 Next, a gel coat (polyester resin, etc.) is applied to the surface of the release film 4 to form a product-side gel coat layer 5.
After curing, a glass mat cloth is laminated on top of it to form a product-side glass mat cloth 6. A liquid thermosetting resin such as polyester resin is applied, impregnated and defoamed with a roll, and then cured. , demolding to obtain FRP product 2. FRP product 2 to FRP type 1
When the mold is removed from the mold, the finely uneven profile p (FIG. 3b) formed by the matting agent particles 7 protruding from the surface 4a of the release coating 4 is removed from the surface of the gel coat layer 5 on the product side. Transferred to FRP
A predetermined matte state is imparted to the surface of the product 2.
