施して銀痕を覆い隠す程度のことしか行われていない。[Prior art] Conventionally, in order to supplement the mechanical strength, heat resistance, rigidity, etc. of synthetic resin molded products, glass fiber-reinforced synthetic resin (hereinafter referred to as rFRPJ), in which glass fibers are mixed into synthetic resin, is used as a raw material, for example, by injection molding. It is widely practiced to obtain FRP molded products by extrusion molding or extrusion molding. In addition, there is currently no way to reliably prevent silvery marks that closely resemble silver streaks (hereinafter referred to as "silver marks") that occur on the surface of FRP molded products. The only thing that has been done is to cover up the silver marks by painting them.

ある。[Means for Solving the Problems] The measures taken in the present invention to solve the above problems will be explained with reference to FIG. By bringing the surface sheet material 2 into close contact with each other, an FRP molded product 1 having a rough surface 3 directly transferred from the rough surface sheet material 2 is taken. In addition, regarding the manufacturing method of this FRP molded product 1, after cooling and solidifying the rough surface sheet-like material 2 while keeping it in close contact with the surface of the molten FRP during molding to form a composite molded product 4, this composite molded product 4 is The method is such that the rough-surfaced sheet material 2 is peeled off from the surface.

用いられる。The rough-surfaced sheet-like material 2 used in the present invention is a sheet-like material having a large number of fine irregularities on one or both sides, for example, a woven or non-woven fabric of synthetic fibers or natural fibers, or a material that has been roughened by sandblasting or the like. A synthetic resin film or sheet is used.

としては、合成繊維の織布が好ましい。The rough-surfaced sheet-like material 2 preferably does not have large through-holes so that the molten FRP does not enter into a wedge shape, solidify, and become firmly integrated with the molded product 1. In addition, in order to prevent strong integration with the molded product 1, it is preferable that the rough-surfaced sheet-like material 2 has little fuzz and is not compatible with the synthetic resin of FRP. These things and
Rough surface sheet material 2 is used because it is easy to obtain suitable unevenness.
A woven fabric made of synthetic fibers is preferable.

without hindering the peeling of the rough-surfaced sheet material 2 after
Any material that can directly transfer unevenness that can be seen with the naked eye to the surface of the molded product 1 is sufficient.
また、粗面シート状物２には、成形品１からの剥離を助

成形品４を得ることができる。The adhesion of the rough sheet material 2 to the surface of the molten FRP is as follows:
This can be done when molding the FRP molded product 1. For example, in injection molding, by inserting the rough sheet material 2 into a mold cavity and performing injection molding, the composite molded product 4 is obtained by bringing the rough sheet material 2 into close contact with the surface of the molten FRP. I can do it.

いても介在させることができる。In order to insert the rough sheet-like material 2 into the mold cavity during the injection molding described above, the method is generally called thermoforming technology.
In accordance with the case of the aged synthetic resin plate, instead of the synthetic resin plate, the roughened sheet strip 2 used in the present invention is clamped over the opening of the mold cavity. If the cavity is shallow, a rough sheet material 2 with poor spreadability can be used. Further, in the case of the rough-surfaced sheet material 2 made of thermoplastic synthetic resin, by preheating it to an appropriate temperature before mold clamping to make it malleable, it is possible to form a considerably deep cavity.

In addition, the unevenness of the FRP surface due to the unevenness of the rough sheet material 2 interacts in a complex manner, preventing layer separation and bubble formation on the FRP surface during cooling, which was previously unavoidable. It is presumed that the formation of a silver layer is prevented.
