According to the present invention, the content of the fiber reinforcing material can be increased, and the mechanical strength of the resulting molded product can be increased. Moreover, a molded article can be formed efficiently.

るものである。In the conventional resin injection molding method or resin transfer molding method, a flash mold is used as a mold. In this molding method, only the fiber reinforcing material is first placed on either a male or female mold, and the mold is clamped. A rubber-like elastic body is used as a backing material for the mating surfaces of the male and female molds. After clamping, resin is press-fitted into the sealed mold through injection holes provided at appropriate positions in the mold, impregnated with the fiber reinforcement material placed in advance, and cured to obtain an FRP molded product. .

。また、繊維含有率が大きいＦＲＰ成形品の場合は注入
された樹脂が成形品全体に回りにくい。In this molding method, resin is injected into a mold that has been placed with fiber reinforcement material in advance and has been clamped to the specified wall thickness of the molded product to create a sealed state, so even low-viscosity resin can be used. Requires large injection pressure. The pressure required for this injection increases as the fiber reinforced plastic (hereinafter abbreviated as FRP) molded product has a higher fiber content. Furthermore, in the case of an FRP molded product with a high fiber content, it is difficult for the injected resin to spread throughout the molded product.

るが、実用化された例はない。According to a practical example of the resin injection molding method, when an FRP mold is used as the mold, unsaturated polyester resin is used as the resin, and glass fiber chopped strand mat is used as the fiber reinforcement, the glass content is approximately 30% by weight.
, the glass content when using a combination of glass fiber roving cloth and chopped strand mat is 40
The amount is usually about 45% by weight. It is thought that it is possible to mold an FRP molded product with a high fiber content by using a mold with high strength and a resin injection device with high injection pressure, but there is no example of this being put to practical use.

０重量％程度である。The mat or preform matte die molding method uses a fiber reinforced material (preformed into a shape similar to a mat or molded product).
The preform (hereinafter abbreviated as preform) is placed in either a male or female mold, the mat or preform is sprinkled with resin, the mold is clamped, and the mold is cured under heat and pressure.
'This is a molding method to obtain RP molded products. In this molding method, after placing the mat or preform on the male mold, if the viscosity of the resin is low during the process of sprinkling resin on the mat or preform, the sprinkled resin may come out of the mold before the mold is closed. It has the disadvantage that it leaks out. In order to improve such defects, the resin used in this molding method is usually a resin mixture whose viscosity is increased by adding a filler or the like. The matte or preform matte die molding method has the disadvantage that it is difficult to mold FRP molded products with a high fiber content compared to when using a resin with a low viscosity because it has no choice but to use a resin mixture with a high viscosity. There is. According to practical examples, when unsaturated polyester resin is used as the resin and glass fiber chopped strand mat is used as the fiber reinforcement material, the glass content is at most 3.
It is about 0% by weight.

もとづき、本発明を完成するに至った。The present inventors used male and female molds with a positive cutout structure, and combined the conventional resin injection molding method and matte or preform matte die molding method. It has been found that the fiber content can be significantly increased by using FRP molded products, and the mechanical strength of the obtained FRP molded products is also high.Based on these findings, the present invention has been completed.

Moreover, even if a resin with low viscosity is injected, there is no fear that the resin will flow out of the mold. In addition, the molding environment is better than the conventional mat or preform matte die molding method in terms of resin scattering, odor, etc. Furthermore, since clamping molding is performed immediately after injection, it is possible not only to produce a molded product with a very high fiber content, but also to arbitrarily select the fiber content.
