It is used in the sports field. Fiber-reinforced resin composite materials used in this field use a prepreg in which a thermosetting resin with relatively good storage stability is impregnated into a reinforcing base material as an intermediate base material, which is shaped and heated in an oven, an autoclave, or the like. The desired molded product is obtained by curing. On the other hand, by utilizing its high strength and high elastic modulus, this fiber-reinforced resin composite material has begun to be used in the field of civil engineering and construction as a substitute for metal or concrete or for reinforcement. However, in this field, since the target object becomes large, and due to its nature, it is mainly used on site construction, so that it is difficult to apply the conventional thermosetting prepreg. Therefore, by adhering the thermosetting prepreg to the object via the room temperature curable adhesive,
A method of curing a prepreg at room temperature has been proposed (JP-A-3-208626). This method does not require heat treatment, but has a drawback that the curing time becomes long. There are also problems that the working environment is deteriorated by the solvent in the adhesive and the surface properties of the cured product are not good.

In advance, two types of resin liquids, a resin liquid A containing the above-mentioned curing agent and a resin liquid B containing the above-mentioned curing accelerator, are prepared. Apply resin solutions A and B on both sides of the reinforcing base material,
If necessary, they can be sequentially laminated and left at room temperature to cause a curing reaction to obtain the desired molded product. Of course, when the lamination is not required, the respective resin liquids permeate from the respective surfaces to cause a curing reaction, and the desired molded product can be obtained. As another method, another reinforcing base material coated with the resin liquid A is laminated on the reinforcing base material coated with the resin liquids A and B so that the resin liquid A and the resin liquid B are in contact with each other, and There is a method in which the resin liquid B is applied to the uncoated surface and, if necessary, these are repeated to form a multi-layer lamination, and then the mixture is left at room temperature to cause a curing reaction to obtain a target molded product. In this case, by adjusting the amount of curing agent and curing accelerator,
It is also possible to deal with the environmental temperature, the size of the molded product, and the like.
Further, the reaction can be promoted by using a heat treatment together if necessary.

A curing reaction may occur. In this case, it is preferable that the reinforcing base material has good permeability, and it is more important not to exceed the upper limit of 1000 g / m 2 , which is a guideline for the amount of the reinforcing fibers. Also in this case, the base material on both ends, for example, if 10 sheets are laminated,
For the 0th sheet, it is more preferable to use a substrate in which the resin liquids A and B are applied to each side. The curing reaction in these cases is preferably carried out in the mold under an appropriate pressure, because the shape of the final molded product becomes stable. Reinforcing work can be performed by using the thus obtained molded product that has undergone the curing reaction and adhering it to an existing building or the like using an adhesive or the like. In addition to this, it can be used as a substitute for metal, concrete, etc. in the fields of aviation, space, sports, or civil engineering / construction.
