Description of the Related Art A fiber-reinforced resin molded product produced by a filament winding method is generally a roving fiber material impregnated with a thermosetting resin liquid, wound around an outer periphery of a mandrel and laminated, and the resin is heated at room temperature or heated to form a resin. It is manufactured by curing.

う欠点がある。In such a manufacturing method, the resin liquid in the roving fiber material wound around the mandrel moves to the outside, the amount of the resin in the roving fiber material on the inner side is reduced, and so-called resin death occurs. . Therefore, there are drawbacks such that cracks and voids are generated in the inner part of the product, and delamination occurs, which lowers the mechanical strength. In addition, there is a drawback that weeping (perspiration) occurs in applications such as piping where internal pressure is applied by a fluid flowing therein.

製造する方法が提案されている。In Japanese Patent Laid-Open No. 64-45625, a half member of a pipe joint is made by a hand lay-up method, the core members of the half joint are joined to each other in a pipe joint shape, and the outer periphery thereof is formed. A method of manufacturing a fiber-reinforced resin pipe joint by winding and laminating a roving fiber material impregnated with a thermosetting resin liquid and curing the resin has been proposed.

ングが生ずることがあり、品質の信頼性に欠ける。According to this method, the generation of cracks and voids in the inner part of the product is prevented, and the occurrence of weeping is also prevented in applications where internal pressure is applied.
However, since the hand lay-up method is used, it takes a lot of time and time for molding, the productivity is poor, and the interlayer adhesion between the core member and the roving fiber material laminated thereon is not sufficient. In addition, weaping may occur from the seam of the half-divided core member, resulting in poor quality reliability.

た。芯部材の厚さは10mmであった。The thermosetting resin liquid comprises 100 parts by weight of unsaturated polyester (Ester R235: manufactured by Mitsui Toatsu Co., Ltd.) and 0.7 part by weight of a thermosetting agent (Kayamek M: manufactured by Kayaku Akzo Co., Ltd.). The content of glass fiber roving was about 40% by volume. The thickness of the core member was 10 mm.

施例１と同様に行った。 Comparative Example 2 A T-shaped mandrel which can be assembled and disassembled as in Example 1 was prepared, and a thermosetting resin liquid was applied to the surface of the mandrel with a brush to a thickness of about 1 mm. The thermosetting resin liquid comprises 100 parts by weight of unsaturated polyester (Ester R235: manufactured by Mitsui Toatsu Co., Ltd.) and 0.7 part by weight of a thermosetting agent (Kayamek M: manufactured by Kayaku Akzo Co., Ltd.). This was heated at 80 ° C. for 7 minutes and then left for 20 minutes to gel the resin solution. Other than that was performed like Example 1.

Further, at the breaking water pressure (40 kg / cm 2 ), weeping (water oozing) did not occur at all. However, it takes 27 minutes in total for heating and leaving to gel the thermosetting resin liquid on the surface of the mandrel, and the productivity is lower than that in Example 1. In addition, the degree of gelation was different for each product and was not stable.

製造することができる。As described above, according to the method for producing a fiber-reinforced resin molded product of the present invention, a curable resin liquid containing a photo-curing agent and a thermo-curing agent is applied to the surface of a mandrel, and this is irradiated with light. To gel the curable resin liquid, wrap the roving fiber material impregnated with the thermosetting resin liquid around the outer periphery, and stack it,
This is a product that cures all resins by heating at room temperature or by heating, so that cracks and voids do not occur inside the molded product, and weeping does not occur in applications where internal pressure is applied by fluid. It can be stably manufactured with high productivity.
