Claim 0:
1. A method for producing a fiber-reinforced plastic using a sheet substrate A,
the sheet substrate A being a substrate including one or more sheets of incised prepreg a,
the incised prepreg a being a prepreg including unidirectionally oriented reinforcing fibers and a resin and having a plurality of incisions dividing the reinforcing fibers formed in the prepreg,
the method for producing a fiber-reinforced plastic comprising a placement step (A) of placing a plurality of sheet substrates A in a mold such that each of the sheet substrates A forms an overlapping portion in which the sheet substrate A overlaps one or more other sheet substrates A and a non-overlapping portion in which the sheet substrate A does not overlap any other sheet substrates A, and a molding step of heating and pressing the plurality of sheet substrates A, and
a total area of the overlapping portion and the non-overlapping portion is 50 to 100% relative to the area of a mold surface;, wherein:, the ratio of the total of the area of the overlapping portion to the total of the area of the non-overlapping portion (“the total of the area of the overlapping portion”/“the total of the area of the non-overlapping portion”) is 0.05 to 0.8;, there is no empty space between the overlapping portion to be bonded; and, the overlapping portion and the non-overlapping portion comprise unidirectional fibers.
