Claim 10:
11. The method for producing a fiber-reinforced plastic according to claim 9, wherein
incisions 1 and incisions 2 are formed in the incised prepreg c,
with the incisions 1, the absolute value of an angle θ1 formed with the fiber direction of the reinforcing fibers satisfies 0°≤θ1<10°, and the average length xc1 (mm) of the incisions satisfies 5 mm≤xc1≤50 mm,
with the incisions 2, the absolute value of an angle θ2 formed with the fiber direction of the reinforcing fibers satisfies 10°<θ2 45°, and the average length xc2 (mm) of the incisions satisfies 0.5 mm≤xc2<2 mm,
substantially all reinforcing fibers contained in the incised prepreg c are divided by the incisions 1 or incisions 2, and the length of the divided reinforced fibers is 0.1 to 15 mm.
